摘要： The invention relates to a process for removal of unwanted, in particular acidic, gas constituents, for example carbon dioxide and hydrogen sulfide, from a crude synthesis gas containing metal carbonyls by gas scrubbing with a scrubbing medium. According to the invention water is added directly into the feed conduit of the methanol water mixture containing metal sulfides before the introduction thereof into the methanol-water separating column and/or water is injected directly into the methanol-water separating column at at least one point. This avoids deposits or encrustations of metal sulfide particles in the methanol-water separating column.

摘要： A hydrocarbon stream is combusted within a reactor to produce soot and syngas. Sub-stoichiometric combustion of the hydrocarbon stream within the reactor converts at least 10% of the carbon in the hydrocarbon stream into soot. The syngas is mixed with a steam stream to produce a hydrogenation feed stream. A shift reactor converts at least a portion of the carbon monoxide and steam to carbon dioxide and hydrogen to produce a shifted gas stream. Water is separated from the shifted gas stream to produce a dehydrated gas stream. The dehydrated gas stream is separated to produce a hydrogen product stream and a recycle stream. The recycle stream is recycled to the reactor.

摘要： A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

摘要： A process for producing syngas that uses the syngas product from an oxygen-fired reformer to provide all necessary heating duties, which eliminates the need for a fired heater. Without the flue gas stream leaving a fired heater, all of the carbon dioxide produced by the reforming process is concentrated in the high-pressure syngas stream, allowing essentially complete carbon dioxide capture.

摘要： A plant and process for producing a hydrogen rich gas are provided, said process comprising the steps of: reforming a hydrocarbon feed in an autothermal reformer thereby obtaining a syngas; shifting said syngas in a shift configuration including a high temperature shift step; removal of CO2 in a CO2-removal section by amine wash thereby forming a hydrogen rich stream, a portion of which is used as low carbon hydrogen fuel, as well as a CO2-rich gas and a high-pressure flash gas stream. The high-pressure flash gas stream is advantageously integrated into the plant and process for further improving carbon capture.

摘要： A process for producing syngas that uses the syngas product from a partial oxidation reactor to provide all necessary heating duties, which eliminates the need for a fired heater. Soot is removed from the syngas using a dry filter to avoid a wet scrubber quenching the syngas stream and wasting the high-quality heat. Without the flue gas stream leaving a fired heater, all of the carbon dioxide produced by the reforming process is concentrated in the high-pressure syngas stream, allowing essentially complete carbon dioxide capture.

摘要： A method for decreasing the SFFC of a steam reforming plant, including establishing a base operating mode. Then modifying the base operating mode by introducing the shift gas stream into a solvent based, non-cryogenic separator prior to introduction into the pressure swing adsorption and introducing the compressed hydrogen depleted off-gas stream in a membrane separation unit, wherein the membrane is configured to produce the hydrogen enriched permeate stream at a suitable pressure to allow the hydrogen enriched permeate stream to be combined with carbon dioxide lean shift gas stream, prior to introduction into the pressure swing adsorption unit without requiring additional compression. Thereby establishing a modified operating mode. Wherein said pressure swing adsorption unit has a modified overall hydrogen recovery. Wherein said modified operating mode has a modified hydrogen production, a modified hydrogen production unit firing duty, a modified SCO2e, and a modified SFFC.
