Biogas Purification

This paper presents an overview of biogas purification technology and industry status, studies the purified rules in biogas purification processing and a lot of experiments are made to verify the influence of purification efficiency by various influencing factors. Carbon dioxide in biogas, which occupies at least 30%, can be absorbed by the lye based on the acid-base neutralization reaction and the absorption efficiency can be improved by controlling the inlet pressure and other factors in the biogas purification processing. The experimental results show the purification rules that purification efficiency of biogas is proportional to concentration ratio of methane and carbon dioxide before reaction, inlet pressure, fluid volume of lye, lye concentration and volume of filler, but inversely proportional to the total inlet flow, which builds theoretic foundation for the later design of the biogas purification device.
