METHOD AND SYSTEM FOR PRODUCING LIQUID FUEL AND GENERATING ELECTRIC POWER

摘要

A method and a system wherein hydrocarbon gases, such as natural gas, are subjected to steam reforming with a steam reformer to yield a reformed gas, gasoline is synthesized from the reformed gas via methanol in a methanol synthesis tower and a gasoline synthesis tower to thereby produce a liquid fuel and, simultaneously therewith, some of low-pressure steam obtained by heat recovery from the reformed gas is superheated in a superheater with some of medium-pressure steam obtained by heat recovery in the methanol synthesis tower or gasoline synthesis tower, and the steam which has been rendered in an unsaturated state is supplied to a low-pressure steam turbine.
