Producing Hydrocarbons From Catalytic Fischer-Tropsch Reactor

摘要

An integrated plant for the conversion of a hydrocarbon gas such as natural gas to useful hydrocarbon liquid fuels and feed-stocks comprises an H2+CO syngas generation system which provides feed gas to a Fischer-Tropsch catalytic hydrocarbon synthesis system with an associated power and heat energy system.

主权项

1. An integrated system for the production of hydrocarbons, comprising:
a POX in which hydrocarbon fuel gas is partially oxidized in the presence of oxygen gas to produce a first intermediate synthesis gas product; a GHR in combination with the POX in which hydrocarbon fuel gas is reformed with steam to produce a second intermediate synthesis gas product which is combined with the first intermediate synthesis gas product to form a synthesis gas product stream; a gas turbine in which an oxidant gas is compressed to produce compressed oxidant gas, a combustion fuel gas is combusted in the presence of at least a portion of said compressed oxidant gas to produce combustion product gas and said combustion product gas is expanded to produce power and expanded combustion product gas; heat exchanger for heating a first steam stream against a stream of expanded combustion product gas to produce a heated first steam stream; a first conduit for supplying the stream of expanded combustion product gas from the expanding means to the first heat exchange means; a second conduit for supplying at least a portion of the heated first steam stream from the first heat exchange means to the synthesis gas generation system; an air separation unit (“ASU”); an element for transferring at least a portion of the power produced by the gas turbine to the ASU; and a Fisher-Tropsch catalytic reactor process with more than one stage of reaction and product liquid hydrocarbon separation including the removal of at least a portion of the CO2 present in the separated off-gas from the first stage or second stage using a CO2 separation process.
