Abstract

A process and system which improves the capacity and efficiency of a power plant. A LNG supply system fuels the plant. Gasified LNG in a combustor mixes with the air from an air compressor to provide the hot combustion gas for a gas turbine. The expanding LNG is used to chill a heat exchange fluid, e.g. water, which heat exchange fluid cools and densifies the intake air for the air compressor. Subsequently, the heat exchange fluid is used in another heat exchange step and is then re-chilled and recycled to cool and densify the intake air.
