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 by gas scrubbing with a scrubbing medium. According to the invention the flash gases obtained during the decompression of the laden scrubbing medium are supplied to a recompressor in order to recycle these to the crude synthesis gas and thus utilize them materially after the recompression. Alternatively or in addition the flash gases may also be supplied to a decompression turbine to recover refrigeration and mechanical work. If the recompressor and/or the decompression turbine are/is designed to have multiple stages, the flash gases obtained at different pressure levels are preferably supplied to a corresponding pressure level of the recompressor and/or of the decompression turbine.

摘要： A petroleum residue stream is heated and reacted with an oxygen stream and a carbon dioxide stream in a gasification unit to produce syngas. At least a portion of the carbon monoxide is converted into carbon dioxide to produce shifted syngas. At least a portion of the shifted syngas is separated to produce a syngas feed stream. At least a portion of the syngas feed stream is converted into methanol. At least a portion of the methanol is converted into one or more alkenes (olefins). At least a portion of the methanol is reacted with carbon monoxide to produce acetic acid. Carbon dioxide produced in the process can be recycled to the gasification unit to facilitate the production of the syngas.

摘要： The invention relates to a method and to a device for performing a process (P) having at least one heat-consuming process step (F). A first fluid (2), which arises in the process and contains acid gases and water vapor, is cooled indirectly against a second fluid (7), an acidic condensate thus being formed. The invention is characterized in that the first fluid (2) is cooled in at least two successive steps (E1, E2), between which heat for use in the heat-consuming process step (V) is indirectly drawn from the second fluid (10).

摘要： The process of the present invention provides high recovery and low capital cost giving it an economic advantage over previously known purification processes. The present process has particular applicability to the purification of synthesis gases comprising at least hydrogen (H2), carbon monoxide (CO), methane (CH4), CO2, and H2O to obtain a gas stream including at least H2, CO, and CH4, that is substantially free of H2O and CO2. The process also has applicability to the purification of natural gases inclusive of at least CH4, N2, CO2, and H2O to produce a gas stream including at least CH4 and N2, but which is substantially free of H2O and CO2.

摘要： A process and/or system for producing fuel that includes providing biogas, removing carbon dioxide from the biogas, transporting the upgraded biogas to a hydrogen plant; providing the transported upgraded biogas and fossil-based natural gas as feedstock for hydrogen production. The carbon intensity of the fuel is less than 11 gCO2-eq/MJ, at least in part because carbon dioxide removed from the biogas and carbon dioxide from hydrogen production is captured and stored.

摘要： The invention relates to a process and a plant for staged separation of concomitants from a raw synthesis gas stream to produce synthesis gas and a sulfur-free naphtha product as a by-product, To remove naphtha compounds and sulfur-containing concomitants, raw synthesis gas is treated with a scrubbing medium in a prescrubbing stage and withdrawn from the prescrubbing stage, and the laden scrubbing medium is mixed with water to bring about a phase separation into a scrubbing medium-water mixture and naphtha, wherein sulfur-containing concomitants are in solution in naphtha. To remove the sulfur-containing concomitants the naphtha is heated to obtain sulfur-free naphtha as a by-product of the gas scrubbing.

摘要： A plant and a method for the production of hydrogen and bicarbonate. The plant includes a gasifier, a reformer, a direct contact exchanger and an apparatus for the production of bicarbonate. The plant is suitable for receiving fuel, oxygen, water, carbonate, brine at the inlet and for producing hydrogen, bicarbonate and calcium chloride at the outlet. The plant uses a self-cleaning direct contact heat exchanger to cool the syngas downstream of the reformer and to produce the superheated steam that feeds the gasifier: this heat exchanger allows the production of hydrogen at low costs and in modular plants.
