Combined with methanol's indirect use in power system, methanol and dimethyl-ether steam reforming use gas turbine exhaust gas to constitute the chemically recuperative gas turbine cycle.

Integratedgasification combined cyclesystem, using both gas and steam turbine offers significant improvement in overall system efficiency an.

The indirect combined cycle, which consists of a steam cycle and a nitrogen gas turbine cycle with a pre-cooler, could be the first choice.
