  • Publication number: 20240335786
    Abstract: The invention relates to a process for separating carbon dioxide from a raw hydrogen product stream to produce a hydrogen product stream and a carbon dioxide product stream. The process includes the absorption of carbon dioxide in an absorption stage in an absorption medium and subsequent desorption of the carbon dioxide from the laden absorption medium in a plurality of decompression stages. According to the invention carbon dioxide substreams withdrawn from the decompression stages are combined into a carbon dioxide total stream and compressed in a plurality of serially arranged compression stages. Each compression stage having a suction pressure value is assigned at least one decompression stage with a corresponding desorption pressure value and the number of decompression stages corresponds at least to the number of compression stages.

  • Patent number: 12109528
    Abstract: Process and plant for membrane permeation treatment of a carbon dioxide and methane-containing biogas stream in which the biogas stream is compressed with a compressor and the compressed biogas stream is fed to a membrane separation unit comprising first and second modules each containing at least one membrane selective for carbon dioxide over methane. The first module separates the compressed biogas stream into a first, second, and third methane-deficient permeates (in comparison to the biogas stream) and a first methane-enriched retentate (in comparison to the biogas stream). The first permeate being richer in methane than the second or third permeates. The second module separates the first permeate into a fourth methane-deficient permeate and a second methane-enriched retentate. The second and third retentates are recycled back to an inlet of the compressor.

  • Publication number: 20240327216
    Abstract: The present invention relates to a process and plant for producing a hydrogen- and carbon oxides-having synthesis gas by partial oxidation of a carbonaceous feedstock having nitrogen compounds. The invention takes advantage of the different solubility of NH3 and CO2 as the synthesis gas stream is cooled. Water is condensed continuously throughout the cooling of the synthesis gas stream. NH3 preferentially dissolves or condenses into the liquid phase during cooling, but at relatively high temperatures, above about 80 to 100° C. Further condensation at lower temperatures then preferentially dissolves or condenses CO2 into the liquid phase. Thus, the formation of ammonium salts during cooling of the synthesis gas is prevented.

  • Publication number: 20240327215
    Abstract: The invention relates to a partial oxidation reactor (POX reactor) for producing a raw synthesis gas stream by partial oxidation of a carbon-containing input stream in gaseous form, in liquid form or in solid, particulate form dispersed in a carrier liquid or a carrier gas in the presence of an oxygen-containing oxidant stream and optionally a moderator stream containing steam and/or carbon dioxide. The invention further relates to a process for producing a raw synthesis gas stream. The partial oxidation reactor according to the invention provides for introducing a cylindrical or frustoconical inlet region having a constant diameter or a diameter that is smaller on the entrance side. The inlet region is arranged upstream of a cylindrical main reactor portion and represents a bottleneck-like section since the largest diameter of the inlet region is smaller than the diameter of the cylindrical main reactor portion.
