The Study and Analysis of different Biogas Enrichment Technologies

Abstract

In a recent developing countries like India  due to increasing number of populations, industrialization, modern agricultural machineries and way of life, the demand of energy at faster rate. To fulfill all the energy needs, large amount of fossil fuels are used with adverse impact on the environment. To overcome this problem the biogas Production is more effective way for converting agricultural waste, sewage waste or municipal waste into renewable energy.To increase calorific value of raw biogas, the upgrading process is very important and crucial.The enriched biogas is used in stationary diesel engine to generate high efficient electricity generation. This paper focused on to study and analyzes different biogas enrichment technologies such as Physical Absorption (water Scrubbing), Pressurised Swing Absorption (PSA), chemical Absorption, cryogenic separation and membrane separation etc. and finds most economical and simplest method. From various biogas upgrading technologies the water scrubbing technology performed well in low investment cost and maintenance cost with simple operation and reliability. In this paper raw biogas is produced and tested in water scrubbing technology and get results 94.69 % methane.
