Abstract
A process for the production of synthesis gas from a hydrocarbon fuel and steam and/or oxygen gas wherein at least part of any steam requirement is provided by heat exchange against exhaust gas from a gas turbine driving an air separation unit supplying at least part of any oxygen requirement for the synthesis gas production. The process is particularly applicable when the synthesis gas is used to prepare a synfuel by methanol synthesis or a Fischer-Tropsch process.
Claims20
A process for the production of synthesis gas, said process comprising:
- reacting hydrocarbon fuel gas with steam and/or oxygen gas in a synthesis gas generation system to produce a synthesis gas product stream;
- compressing an oxidant gas to produce a compressed oxidant gas;
- combusting combustion fuel gas in the presence of at least a portion of said compressed oxidant gas to produce combustion product gas;
- expanding said combustion product gas to produce power and expanded combustion product gas;
- heating a first steam stream by heat exchange against a stream of said expanded combustion product gas to produce a heated first steam stream and using at least a portion of said heated first steam stream to provide at least a portion of the steam for producing the synthesis gas product stream in the synthesis gas generation system;
- and/or
- providing at least a portion of the oxygen gas using an air separation unit (“ASU”) that is driven by at least a portion of the power generated by the expansion of the combustion product gas.
