Abstract
In this work, a large amount of removal of carbon dioxide from biogas could be achieved on a pilot absorption system using monoethanolamine solution as an absorbent. The important parameters influencing on the CO2 removal were investigated. The optimized CO2 removal efficiency could be achieved at the monoethanolamine solution flow of 20 L h-1 and the gas flow of 350 L h-1 when the volume of CO2 was 45 %. The purity of biogas of the resulting gas could be as high as 97-100 %. Moreover, the CO2 removal efficiency reduced with increasing CO2 content of the input gas. The pressure in the absorption tower varying in 0.05 MPa to 0.1 MPa has no significant influence on the CO2 removal. The CO2 removal efficiency could be improved when the volume of the input CO2 was reduced or the content of the monoethanolamine was increased.
