ABSTRACT:
A high pressure synthetic gas stream is produced by gasifying coal. Hydrogen sulfide is removed by contacting the high pressure gas stream with a physical solvent, such as an alcohol, in an absorber column. A low temperature is maintained in the absorber column, typically by chilling both the solvent and the incoming high pressure synthetic gas stream, where a portion of the cooling requirement is supplied by adiabatically expanding the cleaned high pressure gas stream exiting the absorber. Typically, the cleaned high pressure gas stream will be expanded in a turbine expander to provide mechanical energy in addition to cooling capacity. The cleaned synthetic gas is useful as a fuel or chemical feedstock.
