Dimethyl ether (DME), that attracts attention as an alternative fuel for diesel oil recently, is tried to apply for the chemically recuperated gas turbine (CRGT). CRGT is one of the advanced GT cycles, and it can improve power generation efficiency and increase power output. However, some DME-specific concerns are expected unlike in the case of methane or methanol steam reforming that has been already studied. This report discusses three concerns: DME feed system, maximum temperature for the catalyst and by-products such as methane. The pressurized liquid DME should be evaporated by the heat of ultimate flue-gas, and the evaporation requires larger heat duty than that of other liquefied petroleum gas assuming constant heat rate. The other concerns related to process simulation indicates that power generation efficiency of DME-CRGT achieves catalyst reactions should be addressed because they affect configuration of heat recovery equipments or system performance. The result ofover 48% when all concerns are realized in this system.
