GTL-FPSO system for conversion of associated gas in oil fields and stranded gas in stranded gas fields, and process for production of synthetic fuel using the same

摘要

Disclosed are a gas to liquids (GTL)-floating production, storage and offloading (FPSO) system that can be used in offshore oil fields or stranded gas fields and a method for producing synthetic fuel using the same. More particularly, the disclosure relates to a GTL-FPSO system capable of producing liquid synthetic fuel from gas extracted from stranded gas fields or associated gas extracted from oil fields, including a reforming reactor and a liquid hydrocarbon producer, and a method for producing the same.

主权项

1. A gas to liquids (GTL)-floating, production, storage and offloading (FPSO) system for offshore oil fields, comprising:
an FPSO facility comprising a glassy oil separator and an oil/gas separation unit; a reforming reactor; a liquid hydrocarbon producer; an upgrading reactor; a subsea carbon dioxide storage; and an internal power generator;
wherein a hydrogen separator and a carbon dioxide separation unit are provided between the reforming reactor and the liquid hydrocarbon producer and a water separator is provided between the liquid hydrocarbon producer and the upgrading reactor, such that separated water and carbon dioxide, and water and carbon dioxide produced by the internal power generator are recycled to the reforming reactor and surplus carbon dioxide is stored in the subsea carbon dioxide storage,wherein the internal power generator includes a fuel cell that provides electrical power,wherein liquid hydrocarbons that are upgraded by the upgrading reactor are transferred to a product separator, and compounds with 1 to 4 carbon atoms coming from the product separator are transferred to a recycle compressor that recycles the compounds to a prereformer or the reforming reactor, or the compounds are transferred to a boiler to produce electric power.
