A system includes an acid gas removal (AGR) system configured to remove an acid gas from an untreated syngas to generate a treated syngas, a hydrogen separation system configured to receive the treated syngas to generate a non-permeate and a permeate, and an expander configured to expand the non-permeate to generate a cooled non-permeate. The AGR system includes a solvent chiller configured to cool a solvent via heat exchange with the cooled non-permeate.

In one embodiment, a system includes a hydrogen sulfide (H2S) absorber, a first flash tank, a flash gas treatment column, and a CO2 absorber. The system also includes a first fluid path extending sequentially through the H2S absorber, the first flash tank, the flash gas treatment column, the H2S absorber, and the CO2 absorber.

A method for treating a stream comprising an emission gas includes passing portions of the stream comprising the emission gas to two or more reactor units arranged in parallel while subjecting fluid flowing through at least one of the reactor units to pressure control; identifying when at least one of the reactor units trips or is taken out of service; and when at least one of the reactor units trips or is taken out of service, adjusting a flow path of said portion of the stream originally passing to the out-of-service reactor unit such that said portion passes to an absorber for removing the emission gas via a compressor, and subjecting the fluid flowing through all of the in-service reactor units to flow rate control.

A system includes a gas turbine engine that includes a compressor section configured to generate compressed air and a combustor coupled to the compressor section. The combustor is configured to combust a first mixture comprising the compressed air and a first fuel to generate a first combustion gas. The gas turbine engine also includes a turbine section coupled to the combustor. The turbine section is configured to expand the first combustion gas to generate an exhaust gas. The gas turbine engine also includes a boiler coupled to the turbine section. The boiler is configured to combust a second mixture comprising a portion of the first combustion gas and a second fuel to generate a second combustion gas that is routed to the turbine section. In addition, the boiler generates a first steam from heat exchange with the second combustion gas.

A system includes a radiant syngas cooler (RSC). The RSC includes cooling tubing configured to transmit a fluid. The RSC is configured to have a heat transfer area such that the RSC generates a pressure and a temperature of the fluid exiting the RSC to a level allowing for superheating of the fluid to between approximately 750° Fahrenheit and approximately 850° Fahrenheit. Additionally, the heat transfer area is determined based on an amount of heat to be transferred to the fluid as the fluid passes through a heat exchanger in a first path external to the RSC.
