摘要:
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.

An energy conversion process that also exports by-product CO2 at elevated pressure where a fuel gas feed stream is mixed with a reactant stream and additional CO2 is added to at least part of, the fuel gas feed stream, the reactant stream or both through desorption by contacting with a CO2-rich solvent stream in a first stage contactor to produce a mixed feed gas stream and a CO2-lean solvent stream; passing said mixed feed gas stream to a chemical conversion step, where further CO2 is produced; chilling at least part of the products of said chemical conversion step, at a pressure of at least 10 bar to condense and partially remove CO2 as a liquid and thereby produce a CO2-lean gas stream; and passing at least part of said CO2-lean gas stream said to a second stage contactor where further CO2 is removed, by absorption in a solvent stream lean in CO2 derived from said CO2-lean solvent stream, to produce a product gas stream and a solvent stream rich in CO2 from which said CO2-rich solvent stream is subsequently derived.

The present invention features gasification reactor and gas turbine cycle in an IGCC. A gas turbine is coupled to a gasification reactor and drives the gasification reaction. The gasification reactor includes a reduction reaction chamber, a feed stock inlet for introducing the feed stock into the reduction reaction chamber, a gas inlet for introducing an exhaust gas generated by the turbine into the reduction reaction chamber, and a gas outlet for releasing syngas generated by a reduction reaction of the feed stock and the exhaust gas in the reduction reaction chamber. The temperature of the reduction reaction chamber is maintained above 1200° C. and below a non-fluid point of the non-carbonaceous component, such as slag in coal, included in the feed stock.

Disclosed is a process to start-up, operate, and shut down a gasifier and an integrated gasification combined cycle complex with minimal sour gas emissions while additionally reducing the release of contaminants such as carbon monoxide, hydrogen sulfide, and nitrogen oxides. The process is accomplished by starting up with a sulfur free feedstock and by scrubbing any ventable sour gases free of sulfur contaminants prior to release of any such gases to the atmosphere.

A direct-fired coal combustion system includes a swirl chamber having an input configured to receive a coal-water slurry and causing the coal-water slurry to mix with discharge air from a compressor to gasify the coal-water slurry and create a synthesis gas. The system also includes a cyclone separator directly coupled to the second end of the swirl chamber and a second stage combustion input coupled to an output of the cyclone separator.
