Biogas scrubbing, compression and storage: perspective and prospectus in Indian context

Biogas is a clean environment friendly fuel. Raw biogas contains about 55–65% methane (CH 4), 30–45% carbon dioxide (CO 2), traces of hydrogen sulfide (H 2S) and fractions of water vapours. Presently, it can be used only at the place where it is produced. There is a great need to make biogas transpo...

Description
Summary:Biogas is a clean environment friendly fuel. Raw biogas contains about 55–65% methane (CH 4), 30–45% carbon dioxide (CO 2), traces of hydrogen sulfide (H 2S) and fractions of water vapours. Presently, it can be used only at the place where it is produced. There is a great need to make biogas transportable. This can be done by compressing the gas in cylinders which is possible only after removing its CO 2, H 2S and water vapour components. Pilot level trials to compress the biogas have been carried out by a number of earlier investigators working on the subject. This paper reviews the efforts made to improve the quality of biogas by scrubbing CO 2 and the results obtained. There is a lot of potential if biogas could be made viable as a transport vehicle fuel like CNG by compressing it and filling into cylinders after scrubbing and drying. Thus the need emerges for a unified approach for scrubbing, compressing and subsequent storage of biogas for wider applications.
