摘要： A process is described for removing carbon dioxide from a synthesis gas feed stream in a cryogenic separation plant. In an example described the synthesis gas feed stream comprises 40 to 65 mole % hydrogen and is fed to a single stage or a first stage of a series of separation stages at a pressure in the range of 46 to 90 bar absolute. The single stage or a stage of the series is operated at a temperature in the range of -53 to -48 °C and a pressure in the range of 44 to 90 bar absolute. In some examples, the single stage or the combined stages of the series remove 70 to 80 % of the total moles of carbon dioxide in the synthesis gas feed stream. Liquefied CO2 product stream(s) discharged from the stage(s) of the cryogenic separation plant may be sequestrated and/or used in a chemical process. Also described is a process for separating a synthesis gas stream into a hydrogen rich vapour stream and a carbon dioxide rich stream. In an example, the process includes the steps of cooling a synthesis gas stream to a temperature at which at which a two-phase mixture is formed, passing the cooled stream formed in step (a) either directly or indirectly to a gas-liquid separator vessel, the feed to the gas-liquid separator vessel having a pressure of less than 150 bar, withdrawing a hydrogen rich vapour stream from the separator vessel and a liquid CO 2 stream from separator vessel; and feeding a separated hydrogen rich vapour stream to an expansion system including a plurality of expanders arranged in series, wherein the hydrogen rich vapour stream is subjected to expansion in each of the expanders of the series such that an expanded hydrogen rich vapour stream is withdrawn from each of the expanders at reduced temperature and at successively reduced pressures; and using at least one expanded hydrogen-rich vapour stream as a coolant.

摘要： This invention relates to the recovery of carbon dioxide (26) and hydrogen (3,24) concentrated form from shifted a synthesis gas stream comprising hydrogen and carbon dioxide thereby generating a carbon dioxide stream that is sequestered or used for enhanced oil recovery and a hydrogen stream that is used as fuel for a power plant thereby generation electricity. In the process of the present invention a shifted synthesis gas stream is fed to a hydrogen selective membrane separation unit (M101) at a pressure of at least 50 bar gauge and the hydrogen rich permeate stream (3) is fed directly to the combustor of a gas turbine without any requirement to re-compress the hydrogen. The residual gas stream (carbon dioxide enriched stream) from the membrane separation unit is cooled using at least one, preferably, at least two external refrigeration stages (E-101, E-102, E-103, E-104) such that the hydrogen containing offgas (24) is also obtained at above the operating pressure of the combustor of the gas turbine.
