COMBINED PRODUCING METHOD OF ELECTRIC POWER AND LIQUID SYNTHETIC FUEL INCLUDED IN STEAM GAS PLANT Russian patent published in 2009 - IPC C07C27/12 C07C31/04 F02C1/00 

FIELD: power engineering.

SUBSTANCE: combined producing method of electric power and liquid synthetic fuel (methanol) in steam gas plants. Method involves air compression in the main and booster compressors, partial oxidation of hydrocarbon fuel in reactor, cooling of post-reaction mixture, methanol obtaining, and enlargement of incomplete oxidation products and supply thereof to gas turbine combustion chamber. At that, hydrocarbon fuel undergoes consequent oxidation at temperature of 380-450°C and pressure of 4.5-10 MPa with subsequent cooling of post-reaction mixture in cooler-condenser with steam turbine plant condensate. Methanol is separated from liquid oxidation products in rectification column. Specified gas turbine inlet gas temperature is provided either by the assumed number of methanol synthesis reactor plants, or by adding initial hydrocarbon fuel to gas turbine combustion chamber.

EFFECT: improving economical efficiency of obtaining liquid synthetic fuel in steam gas plants, reducing non-production heat losses in steam gas plant cycle, preventing soot formation, and improving operating reliability and efficiency of heat exchange equipment and gas turbine.
