CONFIGURATIONS AND METHODS FOR POWER GENERATION WITH INTEGRATED LNG REGASIFICATION

摘要

LNG cold is used in a plurality of cycles in a combined power plant to increase power output. Especially preferred plant configurations integrate a combined cycle power plant with a regasification operation in which in a first stage LNG cold provides cooling in an open or closed power cycle. Most preferably, a significant portion of the LNG is vaporized in the first stage. In a second stage LNG cold provides cooling for a heat transfer medium that is used to provide refrigeration for the cooling water to a steam power turbine and for an air intake chiller of a combustion turbine in the power plant.
