摘要

Abstract

removal from biogas by water washing system was investigated with various parameters

including liquid/gas ratio

pressure

temperature

and CO

content. The results indicate that CO

removal ratio could reach 34.6%- 94.2% as liquid/gas ratio increased from0.14 to 0.50. Increasing pressure (from0.8 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 CO

content. CO

removal ratio could reach 24.4%-83.2% when CO

content in the simulated gas was 25%-45%. The lowest CO

content after absorption was 2.6% at 1.2MPawith 400 L·h

whichmeets the requirement of CO

content in natural gas for vehicle fuel.
