Full textAbstract:
The impact of the depth of selection of narrow gas oil fractions of Azeri-Chirag-Guneshli oils on the yield and quality of catalytic cracking products was studied. The impact of fractional and group hydrocarbon composition on the main directions of cracking is analyzed. 5 types of gas oil fractions selected in the range of 200-360, 200-410, 200-440, 200-460, and 200-500°C were used as feedstock for catalytic cracking. The results of catalytic cracking of narrow gas oil fractions of Azeri-Chirag-Guneshli oils indicate a nonlinear nature of the dependences on the boiling point limits. The highest total yield of light oil products was obtained by cracking gas oil fractions boiling in the range of 200-410 and 200-440°C, reaching 60.5 and 60.8%, respectively. At the same time, the main contribution to this indicator was made by the gasoline fraction (31.5-33.2%). It was based on paraffin-naphthenic hydrocarbons. The yield of the diesel fraction changed symbiotically with the increasing weight of the fractional composition of the raw material, reaching maximum values of 9.9% during the cracking of the gas oil fraction, boiling in the range of 200-500°C. Based on a comparison of the ratio of iso-butane to iso-butylene, it was concluded that the cracking of gas oil at 200-440°C was accompanied by a significant contribution of bimolecular hydrogen transfer reactions.

Full textAbstract:
In oil-filled high-voltage equipment (power transformers, reactors, current and voltage transformers, switches and bushings), transformer oil performs a number of important functions (heat-removing, insulating, arcing, protective, information and diagnostic). With prolonged use in equipment, the oil undergoes oxidation, which leads to a deterioration in its dielectric properties. In order to slow down the process of oil oxidation and extend the life of liquid insulation, an antioxidant additive ionol (2,6-di-tert-butyl-4-methylphenol) is added to it. Using the method of chromato-mass spectrometry, it was found that ionol decomposes during its consumption with the formation of other phenolic-type compounds, which also exhibit antioxidant activity. In addition, the identified degradation products of ionol can serve as indicators of the state of the liquid insulation as a whole. However, the method of chromatomass spectrometry, for certain reasons, is not used in power grid laboratories. Therefore, in this paper, we propose a method for determining the decomposition products of ionol in their joint presence in operating oil, based on the method of gasliquid chromatography with a flame ionization detector. The implementation of this technique does not require significant investments. In addition, new boundary values of ionol have been established, which should be taken into account when planning the addition of ionol to operating oil in order to prevent a sharp deterioration in its insulating properties.

Full textAbstract:
The study aims to analyse the qualitative characteristics of safflower oil, including its fatty acid profile, and determine the acid and peroxide numbers. The study also investigated the levels of heavy metals in the oil and assessed its potential as an inhibitor of α-amylase and α-glucosidase enzymatic activity. In this study, standardised methods were used to analyse the fatty acid composition of safflower oil using a standard mixture of 37 fatty acid methyl esters (Supelco™ 37 Component FAME Mix), which ensured high accuracy in determining the fatty acid composition. The physical properties of safflower oil, such as density (0.94) and specific gravity (0.917), depend on the fatty acid composition and temperature. The refractive index, determined at 1.469, was used to estimate changes in the oil’s unsaturation and viscosity (45.6 cP). Colour parameters (lightness 45.24, red-green scale -2.87, yellowblue scale 21.04) confirm the authenticity of the oil. The results of gas chromatographic analysis confirmed that the composition of the samples did not meet the requirements of the standard. The study also included the evaluation of the inhibitory activity of safflower oil against the enzymes α-amylase and α-glucosidase, where one of the samples showed significant inhibition of α-amylase activity and the other α-glucosidase activity, indicating their potential use as natural inhibitors. The safety control of heavy metal content showed that the levels of lead, cadmium and other toxic elements in the oil are well below the permissible limits, confirming its safety for consumption. These data indicate that, although some safflower oil samples do not meet the standards for fatty acid composition, its potential as a natural enzyme inhibitor and safety in terms of heavy metal content opens up prospects for further research and possible optimisation of production processes

Full textAbstract:
Each hydrocarbon fraction obtained from crude oil and produced at an oil and gas refinery is further transformed into other hydrocarbon components to produce marketable products. However, as the market demand is satisfied and the consumption/use of hydrocarbon fuels is growing, the environmental damage caused by flaring of substandard hydrocarbons with the formation of various combustion products (including greenhouse gases) is also increasing. Due to the anthropogenic impact on the environment, greenhouse gas emissions into the atmosphere are increasing every year, despite the tightening of environmental requirements, regulations and legislation, since by-products are produced at any production facilities, even if they are fully debugged in operation. Any technological processes used at oil and gas refineries in the world are not initially adapted to work with substandard flare gases, as they are designed to use a specific composition and volume of the required hydrocarbon feedstock, and the main tasks of all existing plants today are to produce products with the highest possible quality and low production of by-products. A new plant has been modeled that is capable of using substandard hydrocarbon gases from an oil and gas refinery as feedstock and returning the resulting products to the production cycle. The plant is powered by renewable energy sources, namely wind turbines, which allows the plant to achieve full carbon neutrality. Rational allocation of resources at oil and gas refineries provides environmental and economic benefits, the new unit allows to completely eliminate the use of flares for burning substandard hydrocarbon gases. Oil and gas refineries can sell products with high added value due to the complete processing of oil and gas raw materials, making a significant contribution to environmental conservation, reducing greenhouse gas emissions into the atmosphere.

Full textAbstract:
This study aims to understand the mechanism of bio-oil gasification and the influence of operating parameters on the properties of the gas products. Firstly, the pyrolysis/gasification of bio-oil was performed using a thermogravimetric analyzer (TGA). The evaporation of gas products from bio-oil were measured on-line with coupled Fourier Transform Infrared Spectroscopy (FTIR). The main gas products were CO, CO2, CH4, H2O, and light hydrocarbons, etc. Organics mainly evolved out at lower temperature (100-200°C), while the cracking of heavy hydrocarbon components took place at higher temperature (>200°C). Simultaneously, the gasification behavior of bio-oil was investigated in a fixed bed gasification reactor under different temperature and residence time. The gas product evolving was checked using micro-gas chromatography. It was observed that the yield of CO and H2 increased with increasing gasification temperature above 600°C, and the maximum value was obtained at 800°C. Prolonging the residence time was not favorable for the upgrading of syngas quality.

<strong>Abstract </strong>The purpose of this study is to obtain fuel products such as gases, aromatics-rich gasoline, gas oil and residuals by visbreaking of used motors-oil sample with desired adequate standard quality. The properties of raw used motors-oil sample were determined. In this research, we noticed that temperature, pressure and residence time have played an important role in determining the yields and the properties of the products. The optimum conditions were determined, at a temperature (t) 445 °C, an absolute pressure (P) 3.4 bar, and residence time (τ) 209 sec. The highest yields of produced cuts especially gasoline and gas oil, have also been obtained and respectively reached the average of optimum conditions to 19.8 wt. % and 27.6 wt.%. Produced gases are of high value and are mainly composed of methane, ethylene, and acetylene in addition to some proportions of normal and iso propane and butane. The yield was about 20 wt.%. The obtained gasoline cut contains 0.19 wt.% of Sulfur and a large proportion of aromatic compounds. The yield of gasoline sample was about 27 wt.%, and mainly contains single ring of aromatic compounds such as benzene, toluene, xylenes, as well as a large proportion of olefinic products. However, the produced gasoline and gas oil are unstable and of low-quality. Three liquid cuts are obtained: gasoline, gas oil and residuals by applying the visbreaking process method for the recovered used motor-oil sample.

Full textAbstract:
Introduction: the oil and gas region economy is highly dependent on tax revenues from oil and gas companies and their service companies, whose profits, in turn, are significantly affected by the volatility of oil and gas prices in the world commodity markets. This determines the relevance of developing new economic approaches to managing the production development of the oil and gas region, taking into account the principle of selectivity in terms of the ratio between the share of oil and gas in regional mining activities and the share of the main types of products of the oil and gas processing industry in the manufacturing industries of a particular region. Objectives: to clarify the scientific category “oil and gas region”, to substantiate and introduce into scientific circulation of the category “inclusive production development of the region” and to pose the problem of the concept “Groningen effect” acceptability at the regional level on the example of the Volga Federal District. Methods: synthesis of institutional, systemic, structural-functional and innovative-technological methodological approaches to managing the production development of the oil and gas region. The criteria for the analysis are the percentage components of the oil and condensate production volumes, as well as natural and associated petroleum gases, in the volume of final production in “Mining” sector. These indicators are mathematically interconnected with indicators of the structure of shipped products in the production of coke and oil products, rubber, and plastic products in the “Manufacturing production” sector; as a result, the region’s oil and gas activity factor was formulated. Results: the author revealed a characteristic of oil and gas region production development, which was called “inclusiveness”. It is based on the investment strategy of diversified high-yield oil and gas revenues of the regional budget into horizontal industrial policy, considering the economic and geological features of oil and gas resource extraction and their quality composition in the Volga-Ural oil and gas-bearing province. The paper proposes the scientific problem “Groningen effect” in the Russian regional conditions and estimates the magnitude of manifestation of said effect by the main types of foreign trade products of the oil and gas region. Conclusions: the developed approach to economic identification of the oil and gas region can become an effective instrument of selective management of its production development under conditions of high volatility of hydrocarbon raw materials quotations, the sanctions on Russian exports and the transition to technological sovereignty.

Full textAbstract:
In the recent years, due to the introduction of new Technical Regulations in the Oil and Gas Industry in 2008, high technical and environmental performance values were set to be met by production volume and by the quality of hydrocarbons and a variety of oil products coming from the fields to factory processing and trade parks. The presence of a powerful raw material base, the shortage of petroleum products and the development of market relations create objective conditions for increased use of a variety of natural hydrocarbons, for improved technological schemes of oil preparation and oil processing on the oil fields and for modernizing the equipment used. On small and remote oil fields, which for economic reasons cannot be linked by transport pipelines, a complex system of preparation of liquid hydrocarbons is used with the ultimate goal of obtaining some refined products such as gasoline, diesel fuel and furnace oil.

A company in the oil and gas manufacturing industry produces gas pipe products using the Polyethylene model. During the period of January to June 2020, the company experienced a defect rate of 2% in the total production. This research utilized a descriptive method to analyze the production process in order to identify and eliminate the rejected products. The objective of this study was to achieve a decrease in defects below 2%. By applying the Six Sigma (DMAIC) method and conducting calculations and analysis, an improvement proposal was developed to address the defects found during the Radiography Test. The proposed solution involves providing specialized training for workers, implementing clear procedures and methods for work, and conducting training sessions to enhance operator skills and understanding of Standard Operating Procedures (SOPs). As a result of the proposed improvements, a comparison of cycle times was conducted. Prior to the implementation of the improvements, the cycle time was 390 minutes. However, after the implementation, the cycle time reduced significantly to approximately 245 minutes. Overall, the proposed improvements aim to reduce the defect rate below 2% and optimize the production process for gas pipe products with the Polyethylene model in the oil and gas manufacturing company.

Full textAbstract:
The results of the study of the process of catalytic cracking of fuel oil on a microspherical zeolite-containing catalyst showed that the cracking of a mixture consisting of hydrotreated vacuum gas oil (85% by weight) and sulfurous fuel oil (15% by weight) leads to an increase in the yield of catalytic distillate by 5.4 – 7.7% by weight, for a mass feed rate of 2 and 4 hours 1, respectively. At the same time, there is a change in the output of all distillate components compared to their output from pure vacuum gas oil. A decrease in coke deposition on the catalyst by 1.9 – 2.6% by weight and an improvement in the quality of the products obtained were found. The content of sulfur and unsaturated hydrocarbons in gasoline obtained from hydrotreated raw materials is less, aromatic compounds are more. Light and heavy gas oils also contain significantly less sulfur. These studies will deepen the oil refining process, increase the yield of catalytic distillate and reduce the environmental burden.

Full textAbstract:
Poor-quality separation of the aqueous gas and oil emulsion leads to large losses of hydrocarbons in the form of increased content of petroleum products in the supply water and droplet liquid in the separated associated petroleum gas. In addition, the residual amount of non-separated gas in oil is released during the storage and transportation of commercial oil, resulting in failure of pumping equipment, forming gas plugs during pipe pumping, and polluting the environment during storage in a tank farm not equipped with a system for capturing light fractions with «breathing» of tanks into the environment during filling and drainage operations. In this work, it is proposed to increase the quality of separation of the aqueous gas and oil emulsion by using a vortex separator, which is a design of a static blade axial vortical apparatus (AVA) inside the pipe. The proposed design will allow pre-separating the gas and liquid phases by imparting angular velocity to the flow of extracted products and increasing centrifugal acceleration, which in turn will increase the rate of gas bubbles from oil and its concentration in the axial flow region, and the rejection of water globules to the wall area with subsequent coalescence into the free phase. Based on the simulation, the design of the AVA ensuring the quality of gas and liquid phases separation was selected. Increasing the number of AVA blades from 6 to 12 contributes to more complete separation. It is proposed to install a static blade axial vortical apparatus in the pipeline before introducing the aqueous gas and oil emulsion into a three-phase separator.

Processing of oil, gas and gas condensate is one of the most widespread areas of modern chemical-technological processes. Due to the safety of chemical and technological process management, strict requirements have been set for the quality of processes in the oil and gas refining and petrochemical industries. During chemical-technological processes in the oil and gas industry, the fractional composition of the product, the typical boiling point, the octane number of gasoline, the cetane number of diesel fuel, the evaporation temperature, the ignition temperature and other parameters must be determined with special accuracy. This set of characteristics is used in the laboratory assessment of the quality of oil, oil products and gas condensate. Temperature measurements performed during such processes must have maximum accuracy. For this reason, the determination of temperature by thermocouples in the above-mentioned chemical processes has been mathematically studied and evaluated during the research.

Full textAbstract:
Pyrolysis of anaerobically digested sludge can serve as an efficient biomass for biofuel production. Pyrolysis produces products like char, bio-oil, and combustible gases by thermochemical conversion process. It can be used for sludge treatment that decreases sludge disposal problems. Sludge produced from anaerobic co-digestion (microalgae, cow dung, and paper) waste has high carbon and hydrogen content. We investigated the candidacy of the anaerobic sludge having high heating value (HHV) of 20.53 MJ/kg as a reliable biomass for biofuels production. The process of pyrolysis was optimized with different temperatures (400, 500, and 600 °C) to produce high quantity and improved quality of the products, mainly bio-oil, char, and gas. The results revealed that with the increase in pyrolysis temperature the quantity of char decreased (81% to 55%), bio-oil increased (3% to 7%), and gas increased (2% to 5%). The HHV of char (19.2 MJ/kg), bio-oil (28.1 MJ/kg), and gas (18.1 MJ/kg) were predominantly affected by the amount of fixed carbon, hydrocarbons, and volatile substance, respectively. The study confirmed that the anaerobic sludge is a promising biomass for biofuel production and pyrolysis is an efficient method for its safe disposal.

Full textAbstract:
A pyrolysis tube furnace system was designed to assess the impact of different components on pyrolysis characteristics under nitrogen atmosphere, and pyrolysis temperature (400 to 900oC) as important factors acting on the samples during pyrolysis. The obtained pyrolysate was classified into three groups, i.e. the condensed liquid product (bio-oil), solid product (bio-char), and light gas. Gas chromatography (GC) was used to analyze ingredients of the light gas released during pyrolysis, and a gas chromatography/mass spectrometer (GC/MS) was used to analyze bio-oil. The results revealed that the volatiles from rice straw pyrolysis exceeded that from lignin at temperatures below 700oC as a result of the higher char generation from lignin pyrolysis. With an increase of pyrolysis temperature, the yield of char decreased and light gas persistently increased, and the yield of bio-tar was maximized at 500oC. In the gas product, H2, CO, CO2 and some light hydrocarbons (CH4, C2H4 and C2H6) could be found, and H2 and CO were abundant. Compounds of bio-oil derived from lignin were simple and consisted of aromatic hydrocarbons, chain hydrocarbon, monoaromatics, and a minor amount of ketones. Phenolic compounds, which comprised 50 to 60%, can be converted easily to obtain high-value chemicals and high quality biofuels.

Full textAbstract:
Catalytic hydrocracking represents an optimal process for both heavy petroleum fractions and Fischer–Tropsch (FT) wax upgrading because it offers high flexibility regarding the feedstock, reaction conditions and products’ quality. The hydrocracking of a heavy vacuum gas oil with FT wax was carried out in a continuous-flow catalytic unit with a fixed-bed reactor and a co-current flow of the feedstock and hydrogen at the reaction temperatures of 390, 400 and 410 °C and a pressure of 8 MPa. The increasing reaction temperature and content of the FT wax in the feedstock caused an increasing yield in the gaseous products and a decreasing yield in the liquid products. The utilisation of the higher reaction temperatures and feedstocks containing the FT wax showed a positive influence on the conversion of the fraction boiling above 400 °C to lighter fractions. Although the naphtha and middle distillate fractions obtained via atmospheric and vacuum distillations of the liquid products of hydrocracking did not comply with the particular quality standards of automotive gasolines and diesel fuels, the obtained products still present valuable materials which could be utilised within an oil refinery and in the petrochemical industry.

The oil and gas industry in Australia consists of a range of complicated joint venture (JV) and processing arrangements. With a future price on carbon in the Clean Energy Future Legislation Package, parties are keen to understand their carbon liabilities where they have interests (both operated and non-operated), and the extent to which a price on carbon can be passed on to customers. Many oil and gas companies have been reporting greenhouse gas emissions from their facilities to the Department of Climate Change and Energy Efficiency since 2009 using the National Greenhouse and Energy Reporting System framework. Subsequently, numerous companies from the sector have developed greenhouse gas reporting systems linking into existing oil and gas production allocation systems. These companies are now turning their attention to using this information to allocate greenhouse gas emissions from their facilities to specific oil and gas sales products, as well as to JV partners. This extended abstract, which includes a case study, explores these developments and discusses the key considerations when allocating greenhouse gas emissions to specific products and JV partners. Also explored are the following questions: What assumptions need to be made at the facility level for emissions associated with extracting, processing and refining specific products ready for sale? How robust and defensible are these assumptions? How do you build these assumptions into a system or model that allocates emissions to different products? What processes do you then put in place to allocate emissions to specific JV partners, and what information will be reported to them and what quality and assurance processes need to be in place to provide comfort to your JV partners of the robustness of the numbers? How will the costs associated with carbon be allocated?

Abstract Pyrolysis together with gasification and combustion create a group of so called thermic processes. Unlike the combustion it is based on thermic decomposition of organic materials without any access of oxidative media. Within the pyrolytic process, three main fractions are created: solid residue, pyrolytic gas and organic liquid product - pyrolytic oil. The presented article examines the effects of pyrolysis operational conditions (above all, temperature) on gas products, solid residues and liquid fractions.

Oil and gas exploration, also known as hydrocarbon exploration, is a process that encompasses many different fields and requires learning about the geological conditions from geophysicists or other geoscientists as well as petroleum professionals in order to locate hydrocarbon reserves such as oil and gas. Mud, gas (H2S, CO2, and CO), and generated water are among the by products of oil and gas exploration. Produced water is one of the potential water resources that could be used by the community for daily needs due to the oil and gas industry's extensive production of it. However, at the moment, produced water is still viewed as industrial waste because it contains dangerous chemicals and other components that are found in oil and gas, which makes it potentially harmful to humans and can pollute the environment. Laboratory tests' findings demonstrate that the produced water samples' results have complied with the established standards for quality

Hydrothermal liquefaction processes (HTL) comprise complex chemical and physical transformations of biomass under the conditions of high temperature and pressure, commonly near- or supercritical water. During this processes, the components of biomass undergo various complicated chemical reactions strongly influenced by process variables. In this study, lignocellulosic biomass (pine wood) has been converted via liquefaction in subcritical water to bio-oil, water-soluble organics, gas and solid products. The process parameters (i.e. temperature and time processing) affecting the bio-oil yields and composition were comparatively studied. The chemical composition of resulting bio-oils was analyzed by means of mid-infrared spectroscopy, gel permeation chromatography, gas chromatography coupled to mass spectrometry and elemental analysis. The maximum bio-oil yield (38.35 wt.%) was obtained at 350 ºC for 10 min. The HHV of the obtained resultant bio-oils varied in the range of 24-28 MJ kg-1. Bio-oils from HTL of pine wood are complex mixtures of aromatic and cyclic compounds with numerous hydroxyl and carboxyl functional groups. The experiments exhibited that the increase in the temperature results in adeeper decomposition of biomass manifested by the higher yield of bio-oil and its gradual deoxygenation. In fact, the obtained oil products are promising, valuable intermediates, which may act as a source of many valueadded chemicals.

Full textAbstract:
Olive oil is one of the basic products in the Mediterranean diet, and, due to its nutritional value, it is becoming more and more widespread in the world. Even though it has traditionally been a rainfed crop, farmers are currently transforming their plantations into super-high-density orchards to increase production. However, the increasingly acute drought in Mediterranean countries forces the establishment of water control mechanisms that allow restriction the contribution of water without undermining the properties of the products obtained. Under this concept, hydroSOS crops and products arose. This study aims to analyze the influence of the application of deficit irrigation on the olive oil obtained from the Arbequina and Arbosana varieties. The sensory parameters descriptive profile and consumers satisfaction degree were measured using trained and consumers’ panels, and the chemical parameters peroxide index, fatty acids, and volatile profile were analyzed using the methods from the International Olive Oil Council and gas chromatography. The experimental results showed that applying this type of irrigation leads to an oil that is more valued by consumers, with a higher concentration of aromatic compounds related with a greener aroma (hexanol, trans-2-hexen-1-ol, hexanal), a higher content of polyunsaturated fatty acids, and greater antioxidant capacity. Deficit irrigation strategies led to environmentally friendly olive oil with high acceptance by Spanish consumers.

The oil of some fields is characterized by a high content of hydrogen sulfide and mercaptans significantly reducing the commercial product quality, besides, due to their high corrosion activity, contribute to emergencies. The oil refining method used at these fields, due to necessity of acid-base effluents neutralizing and the ingress of reaction products into commercial oil, requires adjustment. The article discusses the known physical and chemical methods of hydrogen sulfide and mercaptans removal from oil indicating their advantages and disadvantages. Among the first ones are technologies based on the extraction of undesirable components due to oil separation, rectification or blowing-off. Chemical methods of hydrogen sulfide extraction from well products are based on its extraction with solutions of chemical reagents – hydrogen sulfide absorbers. The most promising among the considered technologies, in our opinion, is the method based on oil blowing-off with hydrocarbon gas. In this technology, the oil extraction from hydrogen sulfide and mercaptans is carried out by passing associated petroleum gas previously purified from hydrogen sulfide through the volume of oil in a column-type apparatus. One of the main advantages of the chosen method is the possibility of associated petroleum gas purification, which also guarantees a reduction in the probability of emergencies, since gas purified from hydrogen sulfide moves through gas pipelines.

PT X is an Indonesian oil and gas processing industry. Recognizing the potential harm posed by gas emissions from oil and natural gas processing, PT X is actively working to control air pollution. One of their initiatives involves the construction of a Sulfur Recovery Unit (SRU) refinery to reduce sulfur gas emissions, particularly from H<sub>2</sub>S, by converting them into liquid sulfur products. The SRU refinery effectively processes approximately 73% of the H<sub>2</sub>S gas emitted during production. In January 2023, air quality measurements were conducted on stack 94-F-403 SRU, revealing the following results: the average concentration of SO<sub>2</sub> emissions was 14.69 mg/m<sup>3</sup>, and the average concentration of NO<sub>2</sub> emissions was 3.04 mg/m<sup>3</sup>. These measurements indicate that both parameters fall below the quality standards set by the Indonesian Minister of Environment Regulation No. 13 of 2009, which defines acceptable emission limits for the oil and gas industry. Based on these findings, it can be concluded that the emissions from stack 94-F-403 SRU are classified as non-polluting, adhering to the Indonesian government's quality standards. PT X's commitment to environmental responsibility is evident through their implementation of the SRU refinery, which significantly reduces gas emissions and ensures compliance with regulatory requirements.

This study explores the enhancement of oil and gas products through laboratory-scale manual formulations to address quality, efficiency, and environmental sustainability challenges. It focuses on biodiesel blends (B10, B30, and B50) and used lubricants treated with citric acid to reduce heavy metal content. The research identifies key functional components in biodiesel that improve combustion efficiency and lower greenhouse gas emissions. Simultaneously, the addition of citric acid in used lubricants aims to reduce metal concentrations, enhancing the potential for recycling and reuse. The results indicate that increasing biodiesel content significantly improves environmental performance and reduces reliance on fossil fuels, though water and sulfur content require strict monitoring to maintain product stability. In used lubricants, the application of citric acid demonstrates varied effectiveness, reducing specific metals like magnesium but increasing others such as calcium and zinc, posing challenges for consistent metal reduction. This study concludes that combining manual formulations and chemical treatments provides valuable insights into optimizing oil and gas products. It emphasizes the need for careful control of component levels to meet quality standards and environmental regulations. The findings suggest that refining the application of citric acid could further enhance its effectiveness in minimizing harmful metal concentrations, supporting sustainable and eco-friendly practices in the oil and gas sector.

This study examines the relationship between oil and gas exports, macroeconomic variables (such as inflation and population), and Indonesia's Gross Regional Domestic Product (GRDP). Specifically, it focuses on seven Indonesian provinces that are the largest oil and gas producers: Aceh, North Sumatra, South Sumatra, Riau, East Java, East Kalimantan, and Papua. Utilizing panel regression analysis, the study analyzes annual data from 2010 to 2022, sourced from the Indonesian Central Bureau of Statistics (BPS) and the respective BPS offices of each province. The findings reveal that oil and gas exports, and total population positively influence GRDP. At the same time, inflation negatively impacts GRDP, particularly in the leading oil and gas-producing regions. Based on these results, the study suggests that the government should consider offering fiscal incentives, such as tax reductions or import duty exemptions. It aims to attract domestic and foreign investment in exploration and production. Furthermore, it advocates for advancements in oil and gas processing technologies to enhance the quality and quantity of oil and gas exports, focusing on finished goods rather than relying solely on raw products.

The article is focused on chemical and radioactive contamination of the environment during hydrocarbon production. The objective of the research is to present relatively unknown facts of indirect long-term environmental effects of hydrocarbon production. Traces of radioactive contamination of soils, ground- and surface water were studied, and also in drinking water in the Republic of Bashkortostan. The authors’ own field and laboratory studies were used. They were performed as part of the preparation of geochemical base map (GHO-1000) of 1:1000000 scale in the Republic of Bashkortostan and in the Ukhto-Izhemsky oil and gas bearing region. The methods applied for laboratory research were inductively coupled plasma mass spectrometry (ICP-MS) for soil and bottom sediment samples and atomic emission spectrometry (ICP-AMS) for ground- and surface waters. It has been determined that in the areas affected by oil production the chemical pollution aspects include deterioration of the groundwater quality caused by associated water and oil products ingress into aquifers due to violation of the oil and gas well drilling techniques, and soil salination caused by frequent equipment breaks during oil production. Aspects of radiation contamination of the environment during oil production include the intake of radionuclides with associated water, and sometimes with heavy hydrocarbon fractions, as well as the consequences of underground nuclear explosions. It is concluded that the territories of hydrocarbon exploration, production and storage should be classified as areas of potential risk for radioactive contamination and chemical pollution (by inorganic compounds, including heavy metal salts). Uranium concentration in drinking water was determined by the INAA method (instrumental neutron activation analysis).

Full textAbstract:
Gas and oil separation plants are the first main step in the production of hydrocarbon products. Depending on the properties of the recovered components from the well heads, and the physical properties in the underground rock reservoir, the plant design can vary in different ways. In mature oil and gas fields, secondary recovery methods are often used, which include the injection of large amounts of water into the underground reservoir, to induce the production flow of the wells. The handling of this water is of significant interest, in terms of production efficiency and pollution reduction, because the water comes into contact with the environment during and after recovery operations. In this work, a model of an exemplary gas and oil separation plant was created in Aspen HYSYS V10. A particular focus was placed on the modeling of oil residues in the water-bearing plant components. This model was then extended by the implementation of different process control schemes, to create a predictive model that could represent dynamic operating states in the plant components. Two different dynamic changes were then simulated using this model, to showcase the capabilities and capacities of the model.

It is worth noting that to date there is little research on this issue, and isolated studies do not fully reflect the impact of the logistics component of the oil and gas industry on economic prospects in Ukraine.
 The article analyzes the logistics component of the oil and gas industry on the example of the "Oil and gas of Ukraine" company. Using the methodology of the task "make or buy" the cost of buying oil and gas has been analyzed and calculated. The study proves that in the case of using oil and gas of own production costs are much lower and the country's dependence on external factors is reduced. The calculation of the cost of transportation of a conditional amount of oil (gas) depending on the chosen mode of transport is given. An attempt is made to demonstrate the impact of various factors in choosing the type of transportation on the final cost of goods. 
 The most profitable type of transportation of oil and gas products is the pipeline. However, there are terms of operation of this type of vehicle, which are often forgotten in the case of its use, which may be accompanied by breakthroughs and large losses of goods. Modern devices with international certification should be mentioned as for the quality and quantity of oil and gas products in warehouses and storage facilities. For equipment that fails, it is necessary to modernize, use the foresight of industry technologies. The results of the study and conclusions reflect the development and impact of the logistics component of the oil and gas industry on economic prospects in Ukraine. The article proves that the analysis of the logistics component of the oil and gas industry on the example of the "Oil and gas of Ukraine" company can become the engine of the modern economy, as it creates a foundation for further development of this industry. Experts and scientists with different views evaluate the research prospects of the oil and gas industry.

The addition of something foreign to lemongrass essential oil has been done since ancient times. One way is to add turpentine oil which aims to increase the volume and grade of the smell. The purpose of this study was to determine the authentication of citronella oil using the gas chromatography-mass spectrometry (GC-MS) method combined with multivariate PCA analysis. Fragrant lemongrass oil was isolated by distillation of water and using simplicia in the form of powdered dried Cymbpogon citratus leaves. The oil obtained was treated with anhydrous Na2SO4. The results of the characteristics and quality requirements of citronella oil are compared with the SNI. The results of GC-MS analysis were the relative levels of essential oils. The results of the characteristic test meet the quality requirements of SNI 06-3953-1995, except for the yield requirements. The results of analysis by GC-MS, the essential content of citronella oil was citronella (37.47%), geraniol (25.03%), trans-caryophilene (3.69%), citronellol (11.68%), and delta cadinene. (2.44%). Chemometric principle component analysis (PCA) can group samples of fragrant lemongrass oil, turpentine oil and lemongrass oil products on the market.

Studies were conducted on some quality characteristics of date seed oil from two date palm cultivars ( Phoenix dactylifera L.): Deglet Nour and Allig. The following values were obtained for Deglet Nour and Allig cultivars respectively: unsaponifiable matter 8.92-7.76%, iodine value 45.49-44.08, total phenols 520.81-220.32µg/g oil, chlorophylls 0.86-0.58µg/g oil, viscosity 18.50-20.50mPa.s, refractive index 1.457-1.462, acidity 1.06-2.10mg KOH/g oil and peroxide index 16.00-25.00meq O2/100g oil. Lipid fractionation of date seed oil yielded 98.30-97.30% neutral lipids, 97.26-96.90% triglycerides, 0.25-0.18% phospholipids and 0.36-0.31% sterols. Gas-liquid chromatography revealed that the major unsaturated fatty acid was oleic acid (39.17-42.13%) while the main saturated fatty acid was lauric acid (24.34-22.56%). Date seed oil showed high medium molecular weight triglycerides (C32-C42, about 27%). Extinction coefficients at 232nm and 270nm increased slightly during 40days in oven (60°C) showing that date seed oil could be easily stored. The production of oil from date seeds provides the use of a renewable resource, and at the same time adding value to agricultural products.

The article is devoted to the problem of complex processing of oil feedstock and increasing the output of light petroleum products, in particular, catalytic cracking gasoline. Currently, the oil refining industry of Kazakhstan is faced with the task of complex processing of hydrocarbon raw materials, increasing the depth of processing and output of light petroleum products. In this connection it is urgent to solve the problem of lack of raw materials for oil refineries of the Republic of Kazakhstan. The complexity of solving the problem of processing residues of oils, fuel oil and intermediates of secondary processes lies in the fact that they contain a large amount of various sulfur compounds. This problem concerns not only domestic refineries, for example, oil from Uzbekistan fields contains a relatively large amount of SO2 compounds, which in turn contains about 1.28% sulphur. The high content of sulfur compounds in oil not only negatively affects the quality and environmental friendliness of manufactured products, but also reduces the service life of equipment and oil refineries. In this regard, the preparation and hydrodesulfurization of raw materials is one of the main issues of intensifying the process of catalytic cracking of petroleum raw materials of "PKOP" LLP. The issues of possibility of modernisation of catalytic cracking process units by including the process of hydrodesulphurisation of feedstock in order to improve the quality and yield of light products when using fuel oil and secondary intermediates having a large volume of various sulphur compounds in their composition have been considered by the authors. To evaluate the influence of the depth of hydrodesulfurisation of feedstock on the yields and composition of catalytic cracking products, the cracking of crude and hydrotreated hydrogenated vacuum gas oil mixed with fuel oil was carried out on a laboratory unit. The experiments were carried out on a fluidised catalyst bed at mass feed rates of 2h-1 and 4h-1, catalyst to feed ratio of 3:1 and temperature equal to 5100 C. The analysis of the experimental data obtained showed that preliminary hydrotreating of a mixture of vacuum gas oil and sulfur fuel oil followed by catalytic cracking increases the depth of oil refining and helps to increase the yield of catalytic distillate, improves its quality, which ultimately leads to a decrease in environmental pollution with sulfur compounds.
