Frontiers in Energy 2022, Volume 16, Issue 5,   Pages 793-811 doi: 10.1007/s11708-022-0821-0

Abstract: CO2 in natural gas (NG) is prone to condense directly from gas to solid or solidify from liquidMeanwhile, CO2 will also affect the calorific value of NG.Based on the above reasons, CO2 must be removed during the NG liquefaction process.In this paper, the phase behavior of the CH4-CO2 binary mixture is summarized,which provides a basis for the process design of cryogenic CO2 removal from NG.
