Abstract: A natural gas purification plant recovers hydrogen sulfide from the desulfurization and decarbonization exhaust gases by liquid phase oxidation sulfur recovery process,and obtains a good desulfurization effect.However,with the change of natural gas composition in recent years,the content of hydrogen sulfide in acidic gas of the liquid phase oxidation sulfur recovery unit exceeds the designed value,which causes the problems of excessive hydrogen sulfide in tail gas and higher agent consumption.In view of these problems and in combination with the characteristics of the liquid-phase sulfur oxidation recovery unit,main factors affecting the desulfurization effect are experimentally studied,and a solution that recycles exhaust gas is proposed in combination with the actual operation in the field.
