  • Heat integration in coal gasification and methanation reaction process
    Patent number: 8024930
    Abstract: A combined Gasification, methanation and power island steam turbine system. The system includes a gasification portion, the methanation portion and a steam turbine portion. The Gasification portion includes the new heat recovery design and associated controls for obtaining a desired steam to dry gas ration of 1.1-2.2. The methanation portion includes first, second and third methanation reactors and associated heat recovery integrated with a high-pressure, low-pressure superheater, and HP economizers. The power Island steam turbine includes a High pressure, Intermediate pressure, low-pressure steam turbine having an input coupled to an output of the superheaters in Methanation process.
