Prodn. of CO and electric power uses an IGCC (integrated gasification combined cycle) flow sheet incorporating a S-cpds. removal unit. A permeable membrane unit is located between the outlet of the quenched gas from the partial oxidation unit and the fuel inlet to the combined cycle gas turbine. The non-permeable stream from the unit is used as a source of CO, whilst the permeate stream is used as fuel for the gas turbine of the combined cycle unit. The permeate stream is used to strip and recovery CO2 from the S-cpds. removal unit. The side stream of gas is taken and is used for methanol synthesis.
