Abstract: Higher molecular weight hydrocarbon compounds or oxygenates are produced from a gas comprising methane in a process comprising the steps of generating synthesis gas (“syngas”) comprising carbon monoxide and hydrogen by reaction of a gas comprising methane with steam and/or an oxidant gas comprising oxygen, producing higher molecular weight hydrocarbon compounds or oxygenates in a syngas conversion process, removing offgas comprising unreacted hydrogen and unreacted carbon monoxide from said syngas conversion process and separating cryogenically unreacted hydrogen from said offgas or from a gas derived therefrom to produce separated hydrogen product that is substantially free of unreacted carbon monoxide and a first cryogenic liquid comprising unreacted carbon monoxide. The unreacted hydrogen is preferably separated from the offgas in a liquid methane wash column.

Abstract: In various implementations, various feed gas streams which include hydrogen and carbon monoxide may be processed for conversion to product streams. For example, the feed gas stream may be processed using the Fischer-Tropsch process. Unconverted hydrogen and carbon monoxide can be recycled using an off-gas catalytic reformer and a gas turbine exhaust gas heat exchanger that will perform preheating duties.

Abstract: In some implementations, a method for separating components includes receiving off-gas from a Fischer-Tropsch hydrocarbon synthesis reaction process. The off-gas is scrubbed with a light oil at least proximate atmospheric temperature to substantially remove a mixture of C3 and C4. The C3 and C4 are separated from the mixture into two separate streams using distillation columns in a Fischer-Tropsch system.

Abstract: Reactive diluent fluid (22) is introduced into a stream of synthesis gas (or “syngas”) produced in a heat-generating unit such as a partial oxidation (“POX”) reactor (12) to cool the syngas and form a mixture of cooled syngas and reactive diluent fluid. Carbon dioxide and/or carbon components and/or hydrogen in the mixture of cooled syngas and reactive diluent fluid is reacted (26) with at least a portion of the reactive diluent fluid in the mixture to produce carbon monoxide-enriched and/or solid carbon depleted syngas which is fed into a secondary reformer unit (30) such as an enhanced heat transfer reformer in a heat exchange reformer process. An advantage of the invention is that problems with the mechanical integrity of the secondary unit arising from the high temperature of the syngas from the heat-generating unit are avoided.

Abstract: In various implementations, various feed gas streams which include hydrogen and carbon monoxide may be processed for conversion to product streams. For example, the feed gas stream may be processed using the Fischer-Tropsch process or a methanol synthesis process. Unconverted hydrogen and carbon monoxide can be recycled at high recovery and/or inert components removed to prevent build-up in the recycle system by using an arrangement of pressure swing adsorption systems designed to recover impure product gas streams.

Abstract: In some implementations, a system may include a compressor, a heat exchanger and an ITM. The compressor is configured to receive an air stream and compress the air stream to generate a pressurized stream. The heat exchanger is configured to receive the pressured stream and indirectly heat the pressurized stream using heat from an oxygen stream from an Ion Transport Membrane (ITM). The ITM is configured to receive the heated pressurized stream and generate an oxygen stream and the non-permeate stream, wherein the non-permeate stream is passed to a gas turbine burner and the oxygen stream is passed to the heat exchanger.

Abstract: In various implementations, feed streams that include ultrapure, high-pressure hydrogen streams and ultrapure, high-pressure nitrogen streams are reacted to produce ultrapure, high-pressure feed gas in a stoichiometric ratio to an ammonia synthesis reactor loop without or independent of including a methanol loop purge gas.

Abstract: In various implementations, methanol is produced using a (CO+H2) containing synthesis gas produced from a combined PDX plus EHTR or a combined ATR plus EHTR at a pressure of 70 bar to 100 bar at the correct stoichiometric composition for methanol synthesis so that no feed gas compressor is required for the feed to the methanol synthesis reactor loop.

Abstract: In some implementations, one or more methods can include producing a hydrogen rich fuel gas for a gas turbine ballasted with nitrogen and steam and superheated to a temperature above its dew point. The fuel gas may have a minimal or reduced content of CO2 or fuel components CO and CH4 which contain carbon so that when combusted in a suitable gas turbine there may be minimal or reduced emissions of CO2 to the atmosphere. These example methods may result in a capture of the bulk of the carbon present in the total natural gas feed as CO2 compressed to pipeline delivery pressure for sequestration.

Abstract: In various systems and processes, synthesis gas generation may be combined. A partial oxidation reactor (POX) and a gas convectively heated steam/hydrocarbon catalytic reformer (GHR) may be combined to produce synthesis gas. In some implementations, a partial oxidation reactor, a gas convectively heated steam/catalytic reformer, and a waste hat boiler may be combined to produce synthesis gas.
