[0002] Biogas is a combustible mixture of gases produced by the fermentation of various organic substances by microorganisms in the absence of air and under suitable temperature and pH conditions. Biogas contains a large amount of corrosive substances that can corrode production equipment, so it needs to undergo a desulfurization process before use.
