Claim Text:
1. A gas to liquids (GTL)-floating, production, storage and offloading (FPSO) system for offshore oil-gas 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 (steam) 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 gas turbine or a steam turbine 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 used to operate a gas turbine or a steam turbine or 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.
