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 said 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 said 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) cooling air in the pre, inter, and after coolers of an air compressor for an air separation unit by indirect heat exchange with liquefied natural gas (LNG), thereby warming said LNG; (2) separating the cooled air from (1) in an air separation unit into a liquid stream of oxygen and a gaseous stream of nitrogen; (3) heating and gasifying said oxygen stream by indirect heat exchange with a heat transfer fluid; wherein said heat transfer fluid is heated by indirect heat exchange with the exhaust gas from a gas turbine; (4) reacting said gaseous stream of oxygen from (3) with a fuel feedstock selected from the group consisting of liquid hydrocarbonaceous fuel, solid carbonaceous fuel, gaseous hydrocarbon fuel, and mixtures thereof in the reaction zone of a partial oxidation gas generator with a temperature moderator to produce a hot effluent stream of fuel gas, and cooling, cleaning, purifying, and saturating with water said effluent stream of fuel gas; and (5) burning said effluent stream of fuel gas from (4) or said effluent stream of fuel gas in admixture with LNG from (1) with compressed air in the combustor of a gas turbine, and discharging the resulting exhaust gas through an expansion turbine for the production of mechanical power and/or electrical energy.
