초록 ▼

Mechanical and electrical power are produced along with synthesis or fuel gas by the partial oxidation process with integrated combustion and steam turbines. By-product vaporized liquefied natural gas for feed to a pipeline for gas consumers is obtained by heat exchange with heat containing streams from the partial oxidation gasification and gas cleaning and purification zone; and optionally from heat containing streams from combustion and/or steam turbine zones which are integrated with the partial oxidation process. Heat from the combustion turbine exhaust gas is used as follows: (1) superheat steam for use in a steam turbine; (2) preheat water saturated clean sulfur-free synthesis or fuel gas with or without supplemental methane enrichment; (3) preheat oxygen gas for the partial oxidation zone; and (4) vaporize LNG. Pre, inter, and after stages of an air compressor are cooled by indirect heat exchange with LNG which is thereby warmed or vaporized.

대표청구항 ▼

A process for the generation of power comprising: (1) vaporizing liquefied natural gas (LNG) or warming liquefied or vaporized LNG by indirect heat exchange with a heat-containing stream from a partial oxidation gasification and gas cleaning and purification zone, with integrated combustion turbine and stream turbine zones for the production of an effluent gas stream selected from the group consisting of synthesis gas, fuel gas and mixtures thereof; wherein said heat-containing stream is selected from the group consisting of hot quench water, flashed gases and steam obtained from depressurized quench water having a temperature in the range of about 150°F. to 600°F., steam produced by indirect heat exchange between boiler feed water and said effluent gas stream, steam condensate from said integrated steam turbine zone, scrubbing water used to clean said effluent gas stream, exhaust gas from said integrated combustion turbine zone, condensate produced by indirect heat exchange between rich acid-gas solvent absorbent from said gas purification zone and steam, free-oxygen containing gas, and combinations thereof; (2) burning said effluent gas stream comprising synthesis or fuel gas from step (1) in the combustor of a gas turbine along with air to produce exhaust gas; and (3) expanding said exhaust gas in an expansion turbine for the production of mechanical power or electricity.
