Abstract:
Existing correlations for predicting solution gas oil ratio, Rs, and oil formation volume factor, Bo, gave standard deviations as high as 50 and 12 percent, respectively, for Nigerian crudes. New correlations developed using 503 Pressure-Volume-Temperature (PVT) data points from 100 Nigerian crude oil reservoirs of the Niger Delta Basin are presented. The correlations for Rs and Bo predict values from different reservoirs within 6 and 2 percent standard deviations, respectively, and will apply to crudes of specific gravity range 0.811 to 0.966. These correlations are applicable to other crudes with characteristics similar to those of Nigerian crudes.

ABSTRACT This study investigated the physical and chemical properties of the residue from in-situ burns of thick oil slicks. It involved burning small-diameter slicks of oil on water and analyzing the properties of the residues. The objective of the work was to identify the burn conditions that might produce residues that sink. Eight oils were selected for the project: (1) Alaska North Slope crude; (2) Alberta Sweet Mixed Blend crude; (3) Arabian Heavy crude; (4) Arabian Light crude; (5) Bonny Light crude; (6) Iranian Heavy crude; (7) Mayan crude; and (8) automotive diesel. Burn tests were conducted on all eight oils when fresh and on two of the oils when weathered. Experiments involved burning slicks of three thicknesses (5, 10, and 15 cm) on saltwater at room temperature (15°C). Residue density, water content, pour point, and viscosity were measured. Samples of parent oils and burn residues were fractionated into three boiling point ranges, and each was analyzed to quantify total saturates, aromatics, resins, and asphaltenes. The results showed that the residues from burns of thicker slicks of heavier crudes and weathered crudes may sink in fresh water or saltwater once they cool to ambient temperatures, whereas burn residues of lighter oils may not sink. Burn residues of all crudes were more dense than their parent oils and were solid or semisolid. Residue density was related to the density of the parent oil, the state of weathering, and slick thickness. Chemical analysis showed that the burn residues were composed almost exclusively of the higher boiling point (HBP) fraction; virtually all of the lower boiling point fraction and almost all of the middle boiling point fraction had been removed. Most, but not all, of the HBP fraction, which included all of the asphaltenes and resins, was preserved in the burn residue. The in-situ burning process appears to be neither a pure equilibrium flash vaporization nor a pure batch distillation, but rather a process lying somewhere between the two ideals. The results of the burns of automotive diesel contrasted strongly with those of crude oils. Diesel burns were far more efficient than those of crude oils, leaving only a few millimeters of residue regardless of the thickness of the original slick. The chemical composition of the residue and its properties were changed only slightly from those of the parent oil. Research on the use of in-situ burning as a marine oil spill countermeasure has resulted in a rapidly growing acceptance of the technique as an option for spill cleanup.

Abstract:
Doutoramento em Engenharia Química
The precipitation of wax in crude oils at temperatures below their pour point leads to the formation of a network structure of waxy crystals and the gelation of the oil. It is thus very important to have a good understanding of the behavior of waxy crude oils during transportation at low temperature, and the rheological behavior of the gelled crude, as this would be useful information for the design and operation of pipeline systems that would help decrease the costs of production and transportation. This thesis was motivated by the lack of information on the characteristics of the wax phase of Libyan waxy crude oils and of their rheological behavior at temperatures below the pour point. The characterization of the oil and wax provides useful information required for operational engineering, and process development, including modifications to the processing of the crude oils. This study used DSC to measure the wax appearance temperature for five Libyan crude oils; the carbon number distribution of these waxes was determined by GC-FID; extensive information about the structural composition of these waxes was obtained using C-NMR; and information about the crystalline structure of these waxes was obtained using X-ray diffraction. A better understanding and more detailed knowledge of the rheological behavior of some Libyan waxy crude oils was developed in this work. The characterization of the rheological characteristic of Libyan waxy oils is an important contribution to the Libyan oil industry. This can be illustrated by the fact that the rheological characterization of gelled waxy oils near their pour point is useful to extract information about the gel structure, the gel strength and to further explore the network stability due to wax deposition, i.e. the flowability of crude oils in pipelines by prediction of the successful start-up pressure and pump capacity required after shutdown. This will allow to avoid operational problems and reduce the cost of production by the use of hazardous chemicals, which are not only costly but also have negative environmental impacts, while minimizing losses by reduced production due to line blockage. Based on the considerations exposed above this thesis focus on the study of the flow behavior of the oils below their pour point temperatures. Furthermore the effect of stress applied on the gelling properties and the gel breakdown of crude oil samples after a specified aging time was investigated. Lastly, in order to explore the elasticity, stability and strength of the crude oils gels we have experimentally studied the viscoelastic properties of the oils above and below the pour point.
A precipitação de cera em petróleos brutos a temperaturas inferiores ao seu ponto de escoamento, conduz à formação de uma estrutura de cristais de cera e à gelificação do óleo. Assim, é muito importante ter uma boa compreensão do comportamento dos óleos brutos e da precipitação de cera durante o transporte a baixa temperatura, bem como do comportamento reológico do crude gelificado, já que esta seria uma informação útil para o projeto e operação de sistemas de oleodutos, e que permitiria diminuir os custos de produção e transporte. Esta tese foi motivada pela falta de informação sobre as características de óleos brutos parafínicos da Líbia e do seu comportamento reológico a temperaturas inferiores ao ponto de fluxão. A caracterização do óleo e da sua cera pode fornecer informação útil necessária para a engenharia operacional e o desenvolvimento de processos, incluindo a modificação do processamento dos petróleos brutos. Este estudo utilizou DSC para medir a temperatura de formação da cera em cinco óleos brutos de petróleo Líbio; a distribuição dos alcanos presentes nestas ceras foi determinada por GC-FID; extensa informação sobre a composição estrutural destas ceras foi obtida usando CRMN; e informações sobre a estrutura cristalina dessas ceras foi obtida usando difracção de raios-X. Neste trabalho tentamos desenvolver um conhecimento mais aprofundado acerca do comportamento reológico de alguns petróleos brutos parafínicos da Líbia. A caracterização reológica de petróleos parafínicos é uma contribuição importante para a indústria petrolifera Líbia. Isto pode ser explicado pelo facto de o comportamento reológico de óleos parafínicos próximo do ponto de fluxão ser útil para caracterizar a estrutura do gel, a sua resistência e a estabilidade da rede resultante da deposição de cera, permitindo assim prever os perfis de escoamento do petróleo em dutos, a pressão de arranque e a capacidade da bomba, minimizando problemas de operação, reduzindo o uso de produtos químicos perigosos e impactos ambientais negativos, e em geral, os custos associados ao processo. Baseado nestes argumentos expostos acima, esta tese foca-se no estudo do comportamento reológico dos óleos selecionados abaixo das suas temperaturas de ponto de fluxão. O efeito da tensão aplicada sobre as propriedades de escoamento e de gelificação e a quebra de gel de amostras de petróleo em bruto, após um tempo de envelhecimento especificado foi investigada. Por último, a fim de explorar a elasticidade, a estabilidade e a resistência dos géis formados por petróleos parafínicos, estudamos experimentalmente as propriedades viscoelásticas dos óleos acima e abaixo do ponto de fluxão.

Abstract:
Understanding the behaviour of heterogeneous systems has been of particular significance to crude oil production. Adsorption of crude oil surface-active species to reservoir rocks and aqueous interfaces has consequences for oil recovery and its separation from water. Therefore, an evaluation of heterogeneous systems involved in crude oil recovery has been the main focus of this thesis. After a general introduction, the thesis is divided into five sections: crude oil chemistry, solid wettability, asphaltene adsorption, emulsion stability and characterisation of interfacial films. The first section considers the chemistry of crude oil through its separation into fractions, based on polarity and solubility differences. The second is the characterisation of oil-brine-rock interactions and wettability alteration of bitumen-coated sand surfaces by nuclear magnetic resonance (NMR) relaxometry, and its relevance in low salinity waterflooding. In the third section, a quantification of asphaltene adsorption on sand is performed in the presence of pre-adsorbed water. The fourth section contains an evaluation of the potential of magnetic resonance imaging (MRI) in the visualisation of crude oil emulsions, with particular emphasis on oil-water separation. The final section is aimed at identifying surface-active species responsible for influencing solid-liquid and liquid-liquid interactions.

Abstract:
Crude oil is of economic importance to any nation. However its poor management and disposal method has resulted in oil spillage and ground contamination. Most emphasis on crude oil contamination on the environment has been on surface and ground water pollution, as well as plants and animals with little or no attention paid to the engineering properties of the contaminated soil. This research is thus aimed at investigating the effect of light crude oil contamination on the geotechnical properties of kaolinite clay soil. This research is a laboratory based experiment in which the contaminated soil was prepared by adding different percentages of light crude oil (2%, 5%, 8%, 10%, 15% and 20%) measured by weight of the dry soil sample and mixed until a uniform mixture was obtained. The British Standard Test Methods for Civil Engineering purposes BS 1377: 1990 (EUROCODE 7: EN 1997: 2-5) was adopted with few modifications. The calculations were based on the fact that the pore space in the contaminated soil is occupied by water and crude oil so water content was calculated from the fluid content and the rate of evaporation of crude oil during oven drying was also considered. The classification results showed that crude oil contamination caused an increase in linear shrinkage, liquid limit, plastic limit and plasticity index between 0% to 20% contaminations. The compaction result showed that there was an increase in maximum dry density while the optimum moisture content decreased between 0% and 15% of crude oil contamination. The result showed that the soil could not compact at 20% contamination and above. Also, the coefficient of permeability increased with increase in the percentage of crude oil contamination while the coefficient of consolidation value (Cv) increases with increase in the percentage of contamination. There was a decrease in the cohesion value and the frictional angle due to the introduction of the crude oil into the soil. Although crude oil altered the geotechnical properties of the kaolinite clay soil and reduced its strength, the soil can still be used for geotechnical purposed after remediation.

Thesis, University of Bradford, 2019. http://hdl.handle.net/10454/18393.

Abstract:
Waxy crude oils (1/3 of oil produced worldwide), pumping through pipelines considered risky operation due to the crude wax content (15-40 wt.%) and to the temperature at which wax supersaturates and precipitates, leading to the danger of pipe blockage, eventually resulting, in multimillion dollars loss in production and maintenance. This research undertaken to develop operational strategy of waxy crude pipelines, considering the crude and crude gel properties and flow conditions. The research problem was approached by characterizing the crude gel with and without additives using chromatography (GC), differential scanning calorimetry (DSC), cross polarised microscopy (CPM), controlled stress and oscillatory shear rheology (CSR and OSR), the principal parameters being the crude temperature and the rate at which the crude was cooled. GC and DSC were useful in establishing wax composition, content and wax appearance temperature (WAT). Control stress rheometer proved to be the most appropriate as it measured the reduction in apparent viscosity at full production (10-50 s-1 shear rate), near shutdown (1 s-1 ) and yielding when the oil was statically cooled. On this basis, it was established that the wax inhibitor was the most effective. CPM revealed that only the wax inhibitor changed the structure of the gel, disrupting its otherwise knitted crystal network. Dilution with the light crude oil merely reduced the wax content and the pour point depressant reduced the gelling temperature. OSR provided a check on CSR and confirmed the gelation temperature measured. CSR provided the yield stress measured, it also provided comprehensive data that can be used for theoretical modelling of this complex flow.

Abstract:
Knowledge of thermodynamic fluid properties, such as density and phase behavior, is important for the design, operation, and safety of several processes including drilling, extraction, transportation, and separation that are required in the petroleum. The knowledge is even more critical at extreme temperature and pressure conditions as the search for more crude oil reserves lead to harsher conditions. Currently, there is dearth of experimental data at these conditions and as such, the predictive capability of the existing modeling tools are unproven. The objective of this research is to develop a fundamental understanding of the impact of molecular architecture on fluid phase behavior at temperatures to 523 K (250 °C) and pressures to 275 MPa (40,000 psi). These high-temperature and high-pressure (HTHP) conditions are typical of operating conditions often encountered in petroleum exploration and recovery from ultra-deep wells that are encountered in the Gulf of Mexico. This PhD study focuses on the fluid phase behavior of a low molecular weight compound, two moderately high molecular weight compounds, three asymmetric binary mixtures of a light gas and a heavy hydrocarbon compound with varying molecular size. The compounds are selected to represent the family of saturated compounds found in typical crude oils. Furthermore, this study reports experimental data for two "dead" crude oil samples obtained from the Gulf of Mexico and their mixtures with methane from ambient to HTHP conditions. A variable-volume view cell coupled with a linear variable differential transformer is used to experimentally measure the high-pressure properties of these compounds and mixtures. The reported density data compare well to the limited available data in the literature with deviations that are less than 0.9%, which is the experimental uncertainty of the density data reported in this study. The phase behavior and density data obtained in this study are modeled using the Peng-Robinson (PR), the volume-translated (VT) PR, and the Perturbed-Chain Statistical Associating Fluid Theory (PC-SAFT) equations of state (EoS). The EoS pure component parameters, typically obtained from the open literature, are derived from fitting the particular EoS to, critical point, or to vapor pressure and saturated liquid density data, or to HTHP density data. For the density data reported here, the PREoS provided the worst predictions, while the VT-PREoS gives an improved performance as compared to the PREoS. However, the PC-SAFT EoS provided the best HTHP density predictions especially when using HTHP pure component parameters. The situation is however reversed in the modeling performance for the phase behavior data whereby the PC-SAFT EoS with HTHP parameters provided the worst vapor-liquid equilibria predictions. Better predictions are obtained with the PC-SAFT EoS when using parameters obtained from fit of the vapor pressure data and is comparable to the PREoS predictions. This reversal in performance is not surprising since the phase behavior data occur at moderately low pressures. The performance of the PC-SAFT EoS is extended to the experimental density data reported for the dead crude oil samples and their mixtures with methane. The PC-SAFT EoS with either set of pure component parameters yield similar predictions that are within 3% of the reported crude oil density data. However, when using the HTHP parameters, the PC-SAFT gives a good representation of the slope of experimental data, which is crucial in the calculation of second-derivative properties such has isothermal compressibility. The PC-SAFT EoS is also employed to model the crude oil HTHP density data for both the dead crude oils and their mixtures with methane using correlations for both the Low-P parameters and the HTHP parameters. The Low-P parameters are derived from fitting the PC-SAFT EoS to pure compound vapor pressure and saturated liquid density data, while the HTHP parameters are obtained from fitting the PC-SAFT EoS to pure compound HTHP liquid density data. Interestingly, the PC-SAFT EoS with the Low-P parameters provided better HTHP density predictions that are within 1.5% of the experimental data for the dead oils than the HTHP parameters that are within 2 to 4% of the data. Density predictions for the dead oil mixtures with methane are however comparable for both sets of parameters and are within 1% on average. However, the PC-SAFT EoS with HTHP parameters clearly provided better representation of the isothermal property, a derivative property obtained from density data, within 10% while predictions with the Low-P parameters can be as high as 37%. The successful completion of the thesis work expands the current knowledge base of fluid phase behavior at the extreme operating conditions encountered by engineers in the petroleum industries. Furthermore, the reported HTHP experimental data also provide a means to scientists and researchers for the development, improvement, and validation of equations with improved modeling performance.

Full text
Abstract:
A study was made of the effect of blending practice upon selected physical properties of crude oils, and of various base oils and petroleum products, using a range of binary mixtures. The crudes comprised light, medium and heavy Kuwait crude oils. The properties included kinematic viscosity, pour point, boiling point and Reid vapour pressure. The literature related to the prediction of these properties, and the changes reported to occur on blending, was critically reviewed as a preliminary to the study. The kinematic viscosity of petroleum oils in general exhibited non-ideal behaviour upon blending. A mechanism was proposed for this behaviour which took into account the effect of asphaltenes content. A correlation was developed, as a modification of Grunberg's equation, to predict the viscosities of binary mixtures of petroleum oils. A correlation was also developed to predict the viscosities of ternary mixtures. This correlation showed better agreement with experimental data (< 6% deviation for crude oils and 2.0% for base oils) than currently-used methods, i.e. ASTM and Refutas methods. An investigation was made of the effect of temperature on the viscosities of crude oils and petroleum products at atmospheric pressure. The effect of pressure on the viscosity of crude oil was also studied. A correlation was developed to predict the viscosity at high pressures (up to 8000 psi), which gave significantly better agreement with the experimental data than the current method due to Kouzel (5.2% and 6.0% deviation for the binary and ternary mixtures respectively). Eyring's theory of viscous flow was critically investigated, and a modification was proposed which extends its application to petroleum oils. The effect of blending on the pour points of selected petroleum oils was studied together with the effect of wax formation and asphaltenes content. Depression of the pour point was always obtained with crude oil binary mixtures. A mechanism was proposed to explain the pour point behaviour of the different binary mixtures. The effects of blending on the boiling point ranges and Reid vapour pressures of binary mixtures of petroleum oils were investigated. The boiling point range exhibited ideal behaviour but the R.V.P. showed negative deviations from it in all cases. Molecular weights of these mixtures were ideal, but the densities and molar volumes were not. The stability of the various crude oil binary mixtures, in terms of viscosity, was studied over a temperature range of 1oC - 30oC for up to 12 weeks. Good stability was found in most cases.

The main objective of this work was to monitor a set of physical-chemical properties of heavy oil procedural streams through nuclear magnetic resonance spectroscopy, in order to propose an analysis procedure and online data processing for process control. Different statistical methods which allow to relate the results obtained by nuclear magnetic resonance spectroscopy with the results obtained by the conventional standard methods during the characterization of the different streams, have been implemented in order to develop models for predicting these same properties. The real-time knowledge of these physical-chemical properties of petroleum fractions is very important for enhancing refinery operations, ensuring technically, economically and environmentally proper refinery operations. The first part of this work involved the determination of many physical-chemical properties, at Matosinhos refinery, by following some standard methods important to evaluate and characterize light vacuum gas oil, heavy vacuum gas oil and fuel oil fractions. Kinematic viscosity, density, sulfur content, flash point, carbon residue, P-value and atmospheric and vacuum distillations were the properties analysed. Besides the analysis by using the standard methods, the same samples were analysed by nuclear magnetic resonance spectroscopy. The second part of this work was related to the application of multivariate statistical methods, which correlate the physical-chemical properties with the quantitative information acquired by nuclear magnetic resonance spectroscopy. Several methods were applied, including principal component analysis, principal component regression, partial least squares and artificial neural networks. Principal component analysis was used to reduce the number of predictive variables and to transform them into new variables, the principal components. These principal components were used as inputs of the principal component regression and artificial neural networks models. For the partial least squares model, the original data was used as input. Taking into account the performance of the develop models, by analysing selected statistical performance indexes, it was possible to conclude that principal component regression lead to worse performances. When applying the partial least squares and artificial neural networks models better results were achieved. However, it was with the artificial neural networks model that better predictions were obtained for almost of the properties analysed. With reference to the results obtained, it was possible to conclude that nuclear magnetic resonance spectroscopy combined with multivariate statistical methods can be used to predict physical-chemical properties of petroleum fractions. It has been shown that this technique can be considered a potential alternative to the conventional standard methods having obtained very promising results.
O principal objetivo deste trabalho foi monitorizar um conjunto de propriedades físico-químicas de correntes processuais pesadas através da espectroscopia de ressonância magnética nuclear, com o intuito de propor um procedimento de análise e processamento de dados em linha para o controlo processual. Vários métodos estatísticos que permitiram relacionar os resultados obtidos por espectroscopia de ressonância magnética nuclear com os resultados obtidos pelos métodos convencionais, aquando da caracterização das diferentes correntes, foram implementados a fim de desenvolver modelos de previsão dessas mesmas propriedades. O conhecimento em tempo real das propriedades físico-químicas dos derivados de petróleo é essencial para otimizar as operações de refinação, garantindo assim operações técnica, económica e ambientalmente adequadas. A primeira parte deste trabalho envolveu a realização de um elevado número de experiências, efetuadas na refinaria de Matosinhos, seguindo métodos convencionais normalizados, importantes para avaliar e caracterizar as correntes de gasóleo de vácuo leve, gasóleo de vácuo pesado e fuel óleo. As propriedades analisadas foram a massa volúmica, viscosidade cinemática, teor em enxofre, ponto de inflamação, resíduo carbonoso, valor P e a destilação atmosférica e de vácuo. Para além da determinação de todas estas propriedades físico-químicas, usando os métodos convencionais, as mesmas amostras foram analisadas por espectroscopia de ressonância magnética nuclear. A segunda parte deste trabalho esteve relacionada com a aplicação de métodos estatísticos multivariáveis que relacionam as propriedades físico-químicas com a informação quantitativa adquirida por espectroscopia de ressonância magnética nuclear. Vários métodos foram aplicados, incluindo a análise por componentes principais, a regressão múltipla por componentes principais, as regressões múltiplas parciais e as redes neuronais artificiais. A análise de componentes principais foi utilizada para reduzir o número de variáveis preditivas e transformá-las em novas variáveis, os componentes principais. Estes componentes principais foram utilizados como variáveis de entrada da regressão múltipla por componentes principais e das redes neuronais artificiais. Na regressão por mínimos quadrados parciais os dados originais foram usados como variáveis de entrada. Tomando em consideração o desempenho dos modelos desenvolvidos, com recurso a parâmetros estatísticos, foi possível concluir que a regressão múltipla por componentes principais contribuiu para piores desempenhos. Melhores desempenhos foram obtidos com a aplicação da regressão por mínimos quadrados parciais e das redes neuronais artificiais. No entanto, foi com os modelos de redes neuronais artificiais que melhores desempenhos foram obtidos em quase todas as propriedades analisadas. Tendo em conta os resultados obtidos, foi possível concluir que a espectroscopia de ressonância magnética nuclear combinada com métodos estatísticos multivariáveis pode ser usada para prever as propriedades físico-químicas de derivados de petróleo. Demonstrou-se que esta técnica pode ser considerada como uma potencial alternativa aos métodos convencionais tendo-se obtido resultados bastantes promissores.

Abstract:
In this study, oleogels were prepared with crude plant oils using varying oleogelators. The role of oleogel was compared with refined oil oleogels as well as commercial shortening in the cookie making process. The plant oils used in this research include solvent-extracted crude soybean oil, refined soybean oil, expeller-pressed corn germ oil, and refined corn oil. β-sitosterol and/or monoacylglycerides, and rice bran wax were used either individually or in combination as the gelator to form oleogels using different oils. The physical properties of oleogels and corresponding cookies were investigated and compared. Overall, the incorporation of gelators into crude and refined oils could produce oleogels with solid-like properties. Refined oils showed higher gelling properties than crude oils. However, the cookie performance of crude and refined oil oleogels were comparable, which indicated that both crude and refined oleogels have the possibility to be used as shortening alternative in cookies.

Abstract Crude fishing oil and fishing dregs are produced from manufacturing process for fishing products. These by-products are generally used as fish freed after being dried. In this study, crude fishing oil is applied to be raw material for biodiesel production. The biodiesel which is alternative fuel for engines or boilers can reduce impact of environmental pollution from fossil fuel. The biodiesel produced from the current process was tested its fuel properties and engine performance. The experimental results show that the biodiesel of crude fishing oil appeared to have larger heating values, cetane index, carbon residue and black smoke opacity while lower flash point in comparison with those of biodiesel from soybean oil. In the aspect of engine performance, biodiesel of crude fishing oil shows to have lower fuel consumption rate and higher brake fuel conversion efficiency. However, the brake fuel conversion efficiency of the super low sulfur diesel appeared to increase and larger than that of the biodiesel when the engine speed increased. The effects of antioxidant on oxidative stability of the biodiesel where studied as well. The biodiesel added with antioxidant has larger methyl ester content while lower acid number, kinematic viscosity and carbon residue. Keyword : Biodiesel, Crude fish oil
