Systems and methods for producing syngas and products therefrom
First Claim
1. A method for reforming a hydrocarbon, comprising:
- combusting at least a portion of an expanded turbine exhaust gas and a first fuel within a first reformer to produce a first reformer exhaust gas;
reforming a hydrocarbon in the first reformer in the presence of one or more first catalysts and steam at conditions sufficient to produce a first reformed hydrocarbon;
heating one or more first transfer mediums by indirectly transferring heat from the first reformer exhaust gas to the one or more first transfer mediums;
powering one or more refrigeration units with thermal energy from the one or more heated first transfer mediums;
cooling one or more second transfer mediums within the one or more refrigeration units to produce one or more cooled second transfer mediums;
transferring heat from one or more oxidants to the one or more cooled second transfer mediums to produce a cooled first oxidant and a cooled second oxidant;
introducing the cooled first oxidant and a second fuel to a gas turbine unit to produce the expanded turbine exhaust gas and mechanical power;
powering a compressor with the mechanical power;
compressing the cooled second oxidant in the compressor to produce a compressed second oxidant; and
introducing the compressed second oxidant and the first reformed hydrocarbon to a second reformer to produce a syngas product.

Abstract
A method can include combusting an expanded turbine exhaust and a first fuel within a first reformer to produce a first exhaust. A hydrocarbon can be reformed in the first reformer to produce a reformed hydrocarbon and heat can be transferred from the first exhaust to a first medium. A refrigeration unit can be powered with thermal energy from the heated first medium and can cool a second medium. Heat can be transferred from one or more oxidants to the cooled second medium to produce cooled first and second oxidants. The cooled first oxidant and a second fuel can be introduced to a gas turbine unit to produce the expanded turbine exhaust and mechanical power. The cooled second oxidant can be compressed in a compressor powered with the mechanical power and the compressed second oxidant and the reformed hydrocarbon can be introduced to a second reformer to produce a syngas.

14. A system for reforming a hydrocarbon, comprising:
-
a first reformer configured to produce a first reformed hydrocarbon and an exhaust gas; one or more first heat exchangers at least partially disposed within an exhaust duct of the first reformer, wherein the exhaust gas transfers heat to one or more first transfer mediums flowing through the one or more first heat exchangers; one or more refrigeration units coupled to the one or more first heat exchangers and configured to receive the one or more heated first transfer mediums, wherein the one or more heated first transfer mediums power the one or more refrigeration units, and wherein the one or more refrigeration units are configured to cool one or more second transfer mediums; one or more second heat exchangers coupled to the one or more refrigeration units and configured to transfer heat from one or more oxidants to the one or more cooled second transfer mediums to produce a cooled first oxidant and a cooled second oxidant; one or more gas turbine units configured to receive the cooled first oxidant, wherein the one or more gas turbine units produce mechanical power and an expanded turbine exhaust gas; one or more compression units configured to receive the cooled second oxidant to produce a compressed second oxidant; and a second reformer configured to receive the compressed second oxidant and the first reformed hydrocarbon and produce a syngas product therefrom. - View Dependent Claims (15, 16, 17, 18, 19, 20)
