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 1.2 MPa） 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%at1.2 MPa 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.
