Abstract

This floating liquefied-gas production facility (1) is equipped with: a gas turbine unit (20); a liquefaction facility (90) that has a primary refrigeration compressor (40) driven by the gas turbine unit (20), and cools natural gas; a drum-circulation-type exhaust heat recovery boiler (30) that recovers the energy of exhaust heat from the gas turbine unit (20) as steam; a component separation system (85) that uses the steam generated by the drum-circulation-type exhaust heat recovery boiler (30) as a heat source to separate components in natural gas obtained from the ocean floor, and sends said components to the liquefaction facility (90); and a fuel gas supply device (100) that compresses end-flash gas and / or boil-off gas, and supplies said compressed gas to the gas turbine unit (20) as fuel.

Description

technical field [0001] The invention relates to a floating body type liquefied gas manufacturing equipment. Background technique [0002] Equipment including a gas turbine may be mounted on marine equipment used in a state of floating on water, such as a ship and a floating structure including a floating body (floating body) floating on the water surface. [0003] Examples of equipment equipped with such a gas turbine include equipment that extracts and liquefies natural gas from an oceanic gas field and mounts it in a gas tank equipped on a gas carrier, power generation equipment that drives a generator with a gas turbine, and the like. [0004] In order to increase the efficiency of these plants, there is a gas turbine combined cycle (GTCC) plant that uses the exhaust gas from the gas turbine to generate steam in an exhaust gas boiler for liquefaction of natural gas driven by a steam turbine driven by the steam compressors, generators. [0005] Patent Document 1 disclose...
