PRODUCTION SYSTEM OF LNG FPSO

摘要

PURPOSE: A natural gas production system for LNG floating production storage offloading (FPSO) is provided to improve energy efficiency by using energy dispersed when the pressure of gas drops. CONSTITUTION: A natural gas production system for LNG FPSO comprises a high-pressure 3-phase separator (50), a turbo expander (80), and an energy recovery device (90). The high-pressure 3-phase separator separates gas ingredients supplied from a gas well from each other. The turbo expander has a rotor (81) rotated by the separated gas ingredients. The energy recovery device is connected to the shaft (83) of the rotor and receives rotation energy outputted from the turbo expander. [Reference numerals] (AA) Following process
