Schematic of integrated natural gas desulfurization plant � Dashed line denotes regeneration gas stream.
CRYOGENIC FRACTIONATION � Distillation � the most w<strong>id</strong>ely used process to separate liqu<strong>id</strong> mixtures � It seems a good prospect for removing CO2 and H2S from natural gas, because the vapor pressures of the principal components are different � However, problems are associated with the separation of CO2 from methane, CO2 from ethane, and CO2 from H2S
