CO2 removal from biogas by water wa

CO2 removal from biogas by water washing system was investigated with various parameters, including liquid/
gas ratio, pressure, temperature, and CO2 content. The results indicate that CO2 removal ratio could reach 34.6%–
94.2% as liquid/gas ratio increased from 0.14 to 0.50. Increasing pressure (from 0.8 to 1.2MPa) could improve gas
purification with a constant inflow rate of gas. Temperature played a key role in the process and lower temperature
in absorption tower was beneficial for reducing CO2 content. CO2 removal ratio could reach 24.4%–83.2%
when CO2 content in the simulated gas was 25%–45%. The lowest CO2 content after absorption was 2.6% at
1.2MPa with 400 L·h-1 gas flow and 200 L·h-1 water flow,which meets the requirement of CO2 content in natural
gas for vehicle fuel.
