Abstract:
The aim of the work is to determine and analyse concentrations of individual biogas components according to the used raw materials based on plant biomass. The measurement is focused on biogas production depending on input raw materials like maize silage, grass haylage and rye grain. The total amount of plant biomass entering the fermenter during the measurement varies at around 40% w/w, the rest is liquid beef manure. The measured values are statistically evaluated and optimised for the subsequent effective operation of the biogas plant. A biogas plant operating on the principle of wet anaerobic fermentation process is used for the measurement. The biogas production takes place during the wet fermentation process in the mesophile operation at an average temperature of 40°C. The technology of the biogas plant is based on the principle of using two fermenters. It follows from the measured results that maize silage with liquid beef manure in the ratio of 40:60 can produce biogas with a high content of methane; this performance is not stable. At this concentration of input raw material, the formation of undesirable high concentrations of hydrogen sulphide occurs as well. It is shown from the results that the process of biogas production is stabilised by the addition of other components of plant biomass like grass haylage and rye grain and a limitation of the formation of hydrogen sulphide occurs. It follows from the results that the maize silage should form about 80% w/w from the total amount of the plant biomass used.

Abstract:
The topic of this paper is the analysis of anaerobic fermentation in an experimental biogas plant. Technological processes and operation parameters were monitored; these processes and parameters include, for example, the optimal structure of the input material and the consideration of the prolonging of the duration of the fermentation process. The goal of prolonging the fermentation process is to obtain higher biogas (and methane) production and to decrease the fermentation residue effluvial emissions. Emphasis is also laid on the mutual co-fermentation of substrates with regard to further use of the results in solving technological problems in other biogas plants. This technological process was first monitored in 2009; that is, before the planned intensification and modernization of the experimental biogas plant. Thus, the evaluation of the process could become part of the planned intensification and modernization of the chosen biogas plant (extended by the addition of the second stage of methanogenesis). The results obtained from the experimental biogas plant, which is one of the pioneering biogas plants in the Czech Republic, may serve, to other biogas operators, as a base for the preparation of suitable input, and for improving the efficiency of anaerobic fermentation within their biogas plants. The goal of the improvement of the fermentation process is to fulfill the ecological aspects; that is, to cut down CO2 emissions and to reduce the negative impact of the fermentation process on the environment (reduction of effluvium and noise originating in biogas plants).

Abstract:
The study aimed to assess the most efficient solution of raw material management in selected biogas plants into the concept of circular economy and evaluate the most efficient solution of raw material management in selected biogas plants due to the quality and quantity of the feed and the final product obtained, which is biogas, as well at the closed circulation (circular economy). The study evaluated two agricultural biogas plants on a real scale and one at the sewage treatment plant (in real scale) in northeastern Poland. A year-long study showed that in technical terms, the best work efficiency is achieved by agricultural biogas plants processing: silage, manure, apple pomace, potato pulp (biogas plant No. 1), followed by biogas plant No. 3 processing chicken manure, decoction, cattle manure, poultry slaughterhouse waste (sewage sludge, flotate, feathers), and finally, the lowest efficiency biogas plant was No. 2, the sewage treatment plant, which stabilized sewage sludge in the methane fermentation process. Moreover, based on the results, it was found that agricultural biogas gives the best efficiency in energy production from 1 ton of feed.

Abstract:
Biogas plants may support the transformation towards renewable-based and integrated energy systems by providing dispatchable co-generation as well as opportunities for biogas upgrading or power-to-X conversion. In this paper, a simulation model that comprises the main dynamics of the internal processes of a biogas plant is developed. Based on first-order kinetics of the anaerobic digestion process, the biogas production of an input feeding schedule of raw material can be estimated. The output of the plant in terms of electrical and thermal energy is validated against empirical data from a 3-MW biogas plant on the Danish island of Bornholm. The results show that the model provides an accurate representation of the processes within a biogas plant. The paper further provides insights on the functioning of the biogas plant on Bornholm as well as discusses upgrading potentials of biogas to biomethane at the plant from an energy perspective.

Abstract:
Biogas plants gain worldwide increasing importance due to several advantages. However, concerning the equipment most of the existing biogas plants are low-tech plants. E.g., from the point of view of instrumentation, control and automation (ICA) most plants are black-box systems. Consequently, practice shows that many biogas plants are operated sub-optimally and/or in critical (load) ranges. To solve these problems, some new biogas plants have been equipped with modern machines and ICA equipment. In this paper, the authors will show details and discuss operational results of a modern agricultural biogas plant and the resultant opportunities for the implementation of a plant-wide automation.

Abstract:
In the biogas plants, organic material is converted to biogas under anaerobic conditions through physical and biochemical processes. From supply of the raw material to the arrival of the products to customers, there are serial processes which should be sufficiently monitored for optimizing the efficiency of the whole process. In particular, the anaerobic digestion process, which consists of sequential complex biological reactions, requires improved monitoring to prevent inhibition. Conventional implemented methods at the biogas plants are not adequate for monitoring the operational parameters and finding the correlation between them. As Artificial Intelligence has been integrated in different areas of life, the integration of it into the biogas production process will be inevitable for the future of the biogas plant operation. This review paper first examines the need for monitoring at the biogas plants with giving details about the process and process monitoring as well. In the following sections, the current situation of implementations of Artificial Intelligence in the biogas plant operation and in the similar industries will be represented. Moreover, considering that all the information gathered from literature and operational needs, an implementation model will be presented.

Abstract:
Ammonia accumulation in biogas plants reactors is becoming more frequently encountered, resulting in reduced methane (CH4) production. Ammonia toxicity occurs when N-rich substrates represent a significant part of the biogas plant’s feedstock. The aim of this study was to develop an estimation method for the effect of ammonia toxicity on the CH4 production of biogas plants. Two periods where a biogas plant operated at 3200 mg·L−1 (1st period) and 4400 mg·L−1 (2nd period) of ammonium nitrogen (NH4+–N) were examined. Biomethane potentials (BMPs) of the individual substrates collected during these periods and of the mixture of substrates with the weight ratio used by the biogas plant under different ammonia levels (2000–5200 mg·L−1 NH4+–N) were determined. CH4 production calculated from the substrates’ BMPs and the quantities used of each substrate by the biogas plant was compared with actual CH4 production on-site. Biogas plant’s CH4 production was 9.9% lower in the 1st and 20.3% in the 2nd period in comparison with the BMP calculated CH4 production, of which 3% and 14% was due to ammonia toxicity, respectively. BMPs of the mixtures showed that the actual CH4 reduction rate of the biogas plant could be approximately estimated by the ammonia concentrations levels.

Abstract:
The optimization of full-scale biogas plant operation is of great importance to make biomass a competitive source of renewable energy. The implementation of innovative control and optimization algorithms, such as Nonlinear Model Predictive Control, requires an online estimation of operating states of biogas plants. This state estimation allows for optimal control and operating decisions according to the actual state of a plant. In this paper such a state estimator is developed using a calibrated simulation model of a full-scale biogas plant, which is based on the Anaerobic Digestion Model No.1. The use of advanced pattern recognition methods shows that model states can be predicted from basic online measurements such as biogas production, CH4 and CO2 content in the biogas, pH value and substrate feed volume of known substrates. The machine learning methods used are trained and evaluated using synthetic data created with the biogas plant model simulating over a wide range of possible plant operating regions. Results show that the operating state vector of the modelled anaerobic digestion process can be predicted with an overall accuracy of about 90%. This facilitates the application of state-based optimization and control algorithms on full-scale biogas plants and therefore fosters the production of eco-friendly energy from biomass.

Abstract:

In order to make the biogas plant at Sobacken located 8 km west of Borås more

profitable you must become aware of flows at the plant. This not only concerning the

incoming waste to the plant but also the use of energy. Since the rebuilding in 2005 of

the plant there has been no follow up concerning the energy use. This thesis is meant

to clarify the use of electricity and heat at the plant. The work determining the use of

energy at Sobacken biogas plant has been done by collecting data from documentation

from the builder Läckeby Water but also by obtaining information from the computer

systems and frequency converters. The results of the study and its calculations shows

that the plant uses approximately 3,2 GWh of electricity per year and 3,1 GWh of

biogas, produced at the plant for heating per year. The production of biogas is

corresponding to 17,7 Gwh per year of which 14,1 GWh reaches the distribution

network. The biogas is used by the city buses but could also be used by private car

owners in Borås refuelling at the newly built tank station at Åhaga. The study does

not only show that the process consumes 6,3 Gwh per year to produce 14,1 Gwh

per year, there is also a large amount of energy being released in secondary energy

flows. These energy flows consists mostly by heat form the cooling system which

could potentially be recovered by heat exchangers and used to heat the process.

Abstract:
The purpose of this project is to build a prototype biogas plant with a cheap control system. The plant is a prototype of a real plant, onto which the control system is to be attached in the future. The prototype does not produce gas, since it has water and air as input substances. The substances are however controlled in the same way as in a gas producing plant. The plant is built mostly of garden hose equipment and plastic buckets. The control system consists of several Arduino Nano which reads sensor values and process the data. All necessary sensor values are displayed by a computer on a graphic interface written in Labview.   The result was a functional control system with some issues as unbalance between outflowing and inflowing amount of water in the digester, difficulties with calibration of the temperature sensor. Therefore it needs further work and testing before attaching on the real plant.

Abstract:
For several years, blooming of algae around the Caribbean islands, including Grenada, has been an issue. This influenced AlgaeFuel Technology into looking at the possibility of biogas production with macroalgal biomass in Grenada. Grenada is dependent on fossil fuels to meet its energy needs. Using the algae for producing biogas could possibly decrease greenhouse gas emissions. There are different factors affecting the production of biogas and therefore, the purpose of this project is to optimize a biogas plant with the use of macroalgal biomass, with focus in Grenada. A literature review was made to gain more knowledge about biogas production through anaerobic digestion, particularly by using macroalgae as biomass. An experiment was made through building four biogas plants in mini format with guidelines from the Swedish University of Agriculture Science. Each plant was fed with different combination of biomass to be compared in biogas production. The result from the experiment gave no clear differences in biogas production which most likely was due to errors during the experiment. Optimizing of a biogas plant includes several aspects. Pretreatment has shown to be an effective way of increasing the methane yield and the biogas production rate. Temperature regulation is significant in order to achieve a more efficient biogas production. The effect of pretreatment and temperature regulation needs to be compared with their energy consumption for a sustainable biogas production. Continues supply of biomass need to be secured which can be done by storing of algae in seasons with abundance and utilization of alternative types of biomass. A combination of biomass through co-digestion is an effective way of increasing the methane yield and also make the biogas plant more efficient in the longer run. In Grenada it is important to prioritize sustainable solutions that can fulfill Grenada’s vision towards 2030, with 100 percent renewable energy. Utilization of macroalgal biomass for biogas production in Grenada can be a solution to both decrease the negative impact of algae bloom and increase the share of renewable energy.
Under flera år har algblomning runt de Karibiska öarna, däribland Grenada, varit ett problem. Detta influerade AlgaeFuel Technology till att se närmare på möjligheterna för biogasproduktion med makroalger som biomassa i Grenada. Grenada är beroende av fossila bränslen för att möta sitt energibehov. Att använda algerna för produktion av biogas kan möjligtvis minska utsläpp av växthusgaser. Det finns olika faktorer som påverkar biogasproduktion och syftet med detta projekt är därför att optimera en biogasanläggning med användning av makroalger som biomassa, med fokus i Grenada. En litteraturstudie gjordes för att få mer kunskaper om biogasproduktion genom syrefri rötning, särskilt med användning av makroalger som biomassa. Ett experiment gjordes genom att bygga fyra biogasanläggningar i miniformat med riktlinjer från Svenska lantbruksuniversitetet. Varje anläggning var matad med fyra olika kombinationer av biomassa för att bli jämförd i produktion av biogas. Resultatet från experimentet gav inga tydliga skillnader i biogasproduktion vilket troligen berodde på felkällor under experimentet. Vid optimering av en biogasanläggning inkluderas flera aspekter. Förbehandling har visat sig att vara ett effektivt sätt att öka utbytet av metan och hastigheten av biogasproduktionen. Temperaturreglering är viktigt för att uppnå en mer effektiv biogasproduktion. Effekten av förbehandling och temperaturreglering behöver jämföras med deras energikonsumtion för att få en hållbar biogasproduktion. En kontinuerlig tillgänglighet av biomassa behövs, vilket kan uppnås genom lagring av alger under säsonger med överflöd samt användning av alternativ biomassa. En kombination av biomassa genom samrötning är ett effektivt sätt att öka metanutbytet och även göra biogasanläggningen mer effektiv i det långa loppet. I Grenada är det viktigt att prioritera hållbara lösningar som kan uppnå deras vision fram mot 2030 med 100 procent förnyelsebar energi. Att använda makroalger som biomassa för biogasproduktion i Grenada kan vara en lösning för att båda minska dom negativa effekterna från algblomning och öka andelen förnyelsebar energi.

Abstract:
Biogas is the most emerging industrial sector for energy production from renewable sources at National and European level. Biogas industry is rapidly developing and in the recent years, several major accidents related to its supply chain happened. These accidents pointed out the need to perform a detailed process safety analysis. Hazards and operability analysis (HazOp) is one of the most used and highly efficient technique, for the identification of potential problems, but the main limitation with this technique is a qualitative nature of the results. Dynamice simulation as a powerful and versatile engineering tool has been adopted in process engineering and also for safety examination in chemical and biochemical process for decades, and it has created possibilities to eliminate or reduce the disadvantages and limitation of conventional process hazard analysis techniques, such as HazOp analysis. The innovation brought by this study, regards mainly to override this limitation by supporting the HazOp analysis using dynamic simulator, by simulating the disturbances and operational failure in a typical biogas production plant, which would help the quantification of HazOp, and improvement of process safety and reliability.

Abstract:
Wången is a trotting school located in Alsen region in Mid Sweden. Currently they keep almost 105 horses in their premises, which produce 2 400 m3 of stall waste per year.  Stall waste has always been a concern for those who keep animals, and though composting has been a viable solution to this problem for quite some time, it is no longer the only solution. Stall waste can be converted to energy and there are different techniques and approaches to do so.  In this study the writer compares the viability of two possible techniques (Biogas and heating plant) by collecting data from two existing biogas and heating plant providers for Wången trotting school. The results show that with almost same amount of investment on the reactors, a heating plant can meet 85% of Wången heating demand while Biogas plant could only meet 10 % of Wången’s heating consumption. On the other hand, as a result of nitrogen bound compound existence in horse manure, burning stall waste in the heating plant showed a more acidifying potential compared to the biogas plant.

Possibilities for energy recovery from sludge at Chişinȃu wastewater treatment plant have been investigated and evaluated. One way of recovering energy from sludge is to produce biogas through anaerobic digestion. Which method of biogas usage that is to prefer in Chişinȃu has been evaluated from a cost-efficiency point of view. There is a possibility that a new waste incineration plant will be built next to the wastewater treatment plant, and therefore solutions that benefit from a co-operation have been discussed. The results show that biogas production would be suitable and profitable in a long time perspective if the gas is used for combined heat and power production. Though, the rather high, economical interest rates in Moldova are an obstacle for profitability.

Full text
Abstract:
Production of biogas is one of several alternatives to meet sustainable energy solutions and waste management. However, managing the by-product (digestate) can be problematic with its high handling costs. Digestate from wet co-digestion biogas plants contains large volumes of water, causing high transportation costs and low concentration of the valuable nutrients. An alternative to try and reduce the associated costs is by processing the digestate. Processing the digestate for volume reduction allow for more economic and resource efficient ways of handling the product. This master thesis was performed on an initiative from Tekniska verken AB and address digestate handling from Linköping biogas plant, a large co-digestion biogas plant in Sweden. The project aimed to find a feasible, more resource efficient management of their digestate by looking at digestate processing alternatives.The approach systematically evaluated a large number of processing techniques by both literature and communication with TvAB or experts. A selection of techniques were further evaluated were studies in laboratory and a market analysis on digestate provided complementary information, aiding the economical evaluation. Results suggest that processing by centrifuge is a viable, economic option when digestate management is costly and a liquid fraction can be recirculated in the process. It has the potential to significantly reducing digestate management costs. Other processing alternatives may be beneficial if transportation distance can be greatly reduced and/or synergies can be found, but the findings in this project suggest that only treatment with centrifuge is of interest. The results are subject to a number of conditions (such as size of the plant) and assumptions (such as recirculation of a liquid fraction) and therefore need individual adaption to be applicable at any specific plant. Conclusive remarks are that although site specific conditions affect the choice of processing, a project such as this may help reducing the necessary time spent on evaluation. Both research process and results may provide valuable findings for similar evaluations in any industry.

Full text
Abstract:

As a part of a large project at Norrmejerier, a biogas production plant has been constructed at Umeå Dairy. In this plant wastewater, residual milk and whey are decomposed and biogas is produced. The biogas is burned in a steam boiler. The biogas plant is designed as an anaerobic contact process, with sludge separation and recirculation by a clarifier. The fat in the substrate is treated in a separate reactor.

The purpose of this study is to evaluate the design and start-up of this biogas production plant. Further, the interaction with the contractor responsible for construction and start-up is evaluated.

The plant is generally well designed, the process conditions are suitable and the objectives are realistic. However, the seed sludge is unsuitable and the time plan is too optimistic.

At the end of the period of this study, the plant was running and all central components are performing as intended. Still, the objectives have not been reached. This is mainly attributed to the poor quality of the seed sludge.

The management of the plant and the interaction with the contractor has generally been good. Most problems that arose were of typical start-up nature. Others were due to insufficient planning or lack of communication. Further, several design flaws were identified during start-up.

Washout of sludge has been one of the most significant drawbacks during start-up. This inconvenience seems to be the result of improper seed sludge and a too hasty increase of the organic loading rate.


Norrmejerier har som en del av ett större projekt låtit uppföra en anläggning för biogasproduktion vid Umeå mejeri. I anläggningen, som är utformad som en anaerob kontaktprocess, behandlas avloppsvattnen och andra organiska restprodukter från mejeriet tillsammans med vassle från både Umeå och Burträsk mejeri. Fettet i substratet avskiljs och behandlas separat. Den biogas som produceras vid nedbrytningen av det organiska materialet bränns i en brännare och ånga produceras.

Syftet med den här studien är att utvärdera anläggningens design, valda processförhållanden och förfarandet under uppstarten av biogasanläggningen. Dessutom utvärderas interaktionen med den tyska entreprenör som är ansvarig för konstruktion och uppstart.

Anläggningens utformning och valda processbetingelser är passande och de uppsatta målen är rimliga. Däremot är valet av ymp olämpligt och tidsplanen för uppstarten är för optimistisk.

När denna studie avslutades var anläggningen i bruk och biogas producerades. Alla de mål för som formulerats hade dock inte uppnåtts. Ympens dåliga kvalitet är den mest bidragande orsaken till att uppstartsperioden har blivit förlängd.

Arbetet under uppstarten och samarbetet med entreprenören har generellt sett varit lyckat. Man har dock stött på många komplikationer, varav de flesta har varit av typisk uppstartsnatur. Andra har varit resultatet av bristande planering och kommunikation. En rad konstruktions- och designfel har också identifierats under uppstarten.

Slamflykt från reaktorerna har varit det mest betydande problemet hos den biologiska processen. Denna förlust av slam förmodas bero på olämpligt val av ymp och en alltför hastig ökning av den organiska belastningen i reaktorerna under uppstarten.

Abstract:
Fossil fuel demand growth in and price fluctuation, depletion resources and supply monopolize, climate change is forcing the restructuring of energy and other industrial and transport area, seeking for renewable energy sources. Using phytoremedial methods in biomass engineering, there is a possibility to create a sustainable method of biomass growth in mid-low contaminated sites soil system. Main aim of the research was to assess the oil-contaminated soil treatment herbaceous plants and their subsequent use for biogas production in order to create a closed cleaning and plant biomass utilization cycle. After the evaluation of the biogas yield and energy conversion efficiency performance it was found that all of the selected herbaceous plant biomass is suitable as raw material for the production of biogas. The biogas potential of selected plants ranged from 377.2 to 822.9 l/kg dry organic matter with an energy value ranging from 7.1 MJ/kg to 17.1 MJ/kg.

Abstract:
This study aims at providing a solution to the difficulty in the production of biogas in cold weather conditions especially during winters and in hilly regions where the temperature remains low throughout the year. As is well known biogas can be produced by anaerobic fermentation of organic materials with the help of bacteria [1]. Meynell [2] pointed out that the production of biogas becomes insignificant when the slurry temperature is less than 15°C. Such situations are usually faced in northern India, where the ambient temperature and, hence, the slurry temperature, in the winters drops below 15°C and hence improper digestion of slurry leads to poor biogas yield. This problem can be overcome by making the biogas plant solar assisted. The heat requirements of the digesters generally consist of three parts; (i) heat required for raising the temperature of incoming slurry for digestion; (ii) for compensating heat losses through the boundaries of the digester and (iii) for compensating losses that might occur in the piping between the heat source and the digester [3]. The required heat is provided from the collector which absorbs solar radiation and converts it into heat which is absorbed by a heat transfer fluid passing through the collector [4]. In this work, a biogas plant for a specified capacity has been designed. Based on the biogas plant dimensions and the average ambient conditions for a specified location, the rate of loss of energy was determined. A solar collector system has been designed to supply sufficient energy to maintain the slurry temperature of 35° C.

Abstract:
Efficient utilization of biomass by a cogeneration system (CGS) is a promising technology for promoting sustainable energy development. Sewage treatment plants are facilities that have been continuously producing biogas by anaerobic digestion. Thus, the potential of a biogas-fuelled CGS in a sewage treatment plant is estimated to be very high. However, there have been few reports on the performance of a biogas-fuelled CGS, particularly regarding the effect of ambient temperature on its performance, and the most efficient arrangement of a biogas-fuelled CGS remains unknown. In this study, performance of a biogas-fuelled CGS was simulated under three typical ambient temperature (low, medium and high) conditions using actual data for a CGS with a micro gas turbine. In the beginning of this study, the relation of energy balance of the plant and ambient temperature was clarified. It was found that the amount of heat demand is ambient temperature-dependent but that the amount of biogas fuel produced is almost constant throughout the year. When a boiler is replaced with a biogas-fuelled CGS to utilize the biogas, under a high temperature condition, the CGS is not able to fully utilize all of the biogas produced, and therefore another pathway of biogas utilization is needed. Under a medium temperature condition, a gas storage system is needed for using biogas efficiently. However, some of the biogas still cannot be utilized efficiently. Under a low temperature condition, since ambient temperature varies greatly between summer and winter, the amount of heat demand of the plant also varies greatly throughout the year. This leads to an imbalance in biogas production and heat demand, and therefore attention must be given to energy management in this condition. The combination of other auxiliary equipment such as a boiler, heat pump and gas storage with the CGS is required in order to cover the total heat demand throughout the year. Four possible arrangements of the CGS with different auxiliary components were proposed and their performances were compared. It was found that all of the proposed CGS arrangements can sufficiently cover the total heat demand by only using biogas produced in the facility. Compared to the conventional system, all proposed CGS arrangements can reduce electrical power demand by 23∼28%, recover 74∼77% of the energy of biogas produced, and utilize almost 100% of the biogas produced. The arrangement with a heat pump is more efficient than the arrangement with a boiler. It was also found that excess biogas in summer can be used in winter by storing the biogas. Thus, a CGS arrangement that includes a gas storage system will enable efficient utilization of biogas and recovered exhaust heat.
