Abstract:

The process flow of combined gasification process of producing coal-based synthetic natural gas is introduced, comparative study is carried out of various kinds of sulfur recovery process technologies, and the sulfur recovery process which is suitable for coal-based synthetic natural gas project is selected through screening. Based on analysis results of the features of combined gasification process which has multi-stream of acidic gas, the sulfur recovery process scheme, i.e., acidic gas pretreatment + two-stage conventional Claus + ammonia process of desulfurization, is put forward.
