and Rahman, S., Prospect of anaerobic co-digestion of dairy manure: A review. The positive effects of the co-digestion concept have been widely reported ( Atandi and Rahman, 2012 Atandi, E. The methane yield from manure is relatively low thus, co-digestion of manure with organic substrates with a high content of lipids, proteins or carbohydrates, is necessary for the biogas plant's economy. and Ellegaard, L., Codigestion of manure and organic wastes in centralized biogas plants. Co-digestion of manure with several organic wastes is a common practice applied in the Danish centralized biogas plants for more than two decades ( Angelidaki and Ellegaard, 2003 Angelidaki, I.
The biogas process is a sustainable process for energy production, waste treatment and recycling of organic waste nutrients. Methane Anaerobic digestion Modelling Co-digestion Manure Subsequently, some experiments were reproduced, in order to evaluate the synergy obtained in the previous simulation and validate the model. The present work investigated the interactions between different simple co-substrates (carbohydrate, lipid and protein) and real co-substrates (corn silage, fodder beet, grass and wheat straw) under co-digestion with manure, in order to verify synergetic effects. This mathematical modelling provides an understanding of the processes and interactions occurring inside the biogas system. Biogas process modelling describes the kinetics and stoichiometry of different steps in the anaerobic digestion process. Co-digestion has become more and more powerful since it is possible, with the use of abundant and cheap substrates, to dilute the inhibitory effects of various other substrates, making the process of anaerobic digestion more efficient and stable. Skid mounted: High Quality standards at workshop, with FAT of interconnection.Biogas production is becoming increasingly important in the environmental area because, besides treating wastewaters, it also generates energy. Tested solution: 2x Operating plants + 1x Plant in construction. Additionally, redundancy on critical items will offer a higher reliability.Īdditional trains can be added to existing plantsĮngineering: Plant is already engineered (only pretreatment has to be adjusted to specific conditions)Ĭivil Works: Skid mounted solution allows easy design and quicker civil Works.ĮlectroMechanical Installation: Easy installation on field (limited amount of on-site welding).Ĭivil Works and Electromechanical Installation can be on the scope of the client. Predesigned and tested trains offer clear advantages on cost and time, even if minor production is required.Īs many 200 TND trains as required can be installed in parallel.
Within this range, N2 Brayton cycle with the proposed technology is the most competitive and safe. This technology change leads into specific higher costs, which are not compensated until significantly larger trains (i.e. Key equipment technology changes when requiring production over 200 TND. HIGH QUALITY: electromechanical construction at workshop (incl.
REDUCED LEAD TIME: below 15 months from downpayment to Start of LNG Production REDUCED COST: significant cost reduction related to state of the art solutions 200 TND Engineered and Skid mounted plant or train
