Beschreibung
Zusammenfassung:	A combined gasification, methanation and power island steam turbine system (100). The system includes a methanation portion (202), and a steam turbine portion (204). The methanation 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 (214), second (216) and third (218) methanation reactors and associated heat recovery integrated with a high -pressure, low-pressure superheater, and HP economizers.. The power Island steam turbine includes turbines an input coupled to an output of the superheaters in Methanation process.
