Biogas purification: Producing natural gas quality fuel from biomass for automotive applications

The different alternative energy sources are available for various applications as the energy needs. But it is found that Bio-Gas can be accepted as energy sources, especially to villages of India, where the conventional energy facilities are scarcely available. Biogas is a valuable fuel of energy containing methane as a responsible major constituent. It is a clean and efficient fuel. This work presents development of scrubbing unit was simple for fabrication, production and operation by using local resources which are available at agriculture field side. an experimental investigation of scrubbing unit was improve the quality of biogas by scrubbing the carbon dioxide (CO₂), hydrogen sulphide (H₂S) content The results obtained are encouraging and will make one of the options to use water scrubbing method on field side to up grade the bio gas as non-conventional energy source for direct use as vehicle fuel as possible as cleanest engine fuel to environment, climate & human health. Out of several methods of biogas enrichment, water scrubbing is found to be a simple, low-cost and suitable method for enrichment of biogas in rural part of our country.
