FPSO GTL production method and GTL production system

摘要

An FPSO GTL production method and a GTL production system are disclosed. The FPSO GTL production method of the present invention is a method for producing GTL (Gas To Liquid) in FPSO, 1) a step of pretreating natural gas produced in an offshore gas field, and 2) pretreatment. A reforming step for producing a synthesis gas containing hydrogen and carbon monoxide by reacting the produced natural gas under a catalyst; and 3) supplying the synthesis gas to a Fischer-Tropsch reactor to cause a reaction. A synthesis step for producing liquid hydrocarbons, and 4) an upgrade step for separating the liquid hydrocarbons into gas, naphtha, and synthetic crude oil and supplying hydrogen to hydrofinishing. It is characterized by.
