摘要： A process for separating sour shifted synthesis gas feedstock into liquid carbon dioxide, a gaseous hydrogen-containing gas and separated sulphur-containing components includes the steps of a. scrubbing the sour shifted gas elevated pressure with an alcohol solvent in a first scrubber and separately recovering an alcohol stream containing the sulphur-containing components and a sweet shifted gas; b. thereafter cooling the sweet shifted gas to a temperature and elevated pressure at which the carbon dioxide contained therein condenses and a two-phase gas- liquid mixture is formed; c. separating the two-phase mixture of stage (b) into separate liquid carbon dioxide and gaseous hydrogen-containing fractions in a fractionation unit; d. extracting residual carbon dioxide from the separated gaseous hydrogen-containing fraction by scrubbing the gaseous hydrogen-containing fraction at elevated pressure with an alcohol solvent in a second scrubber and recovering an alcohol stream containing carbon dioxide; e. feeding the alcohol stream containing carbon dioxide produced in step (d) to the first scrubber and f. warming and expanding the scrubber gaseous hydrogen-containing fraction using at least one heat exchanger to exchange heat with the mixture of step (b) and at least one turbo-expander capable of recovering mechanical work. The process described may be used in for example Integrated Gasification Combined Cycles (IGCC) where the source of fuel is coal or low grade carbon sources such as lignite, tar sands and shale oil.

摘要： A process for separating a mixture of gases into a relatively condensable first component and a relatively non-condensable second component is provided. The first component comprises one or more gases selected from the group consisting of carbon dioxide, carbonyl sulphide and hydrogen sulphide and the second component one or more gases selected from the group consisting of hydrogen, methane, ethane, carbon monoxide, nitrogen, oxygen and synthesis gas. The process itself comprises the following steps: (a) compressing and cooling a mixture of said first and second components in at least one compressor and at least one heat exchanger to a temperature and elevated pressure at which the first components condense and a two-phase gas-liquid mixture is formed; (b) separating the two phase mixture so formed into separate liquid first and gaseous second component fractions in a fractionation unit; (c) extracting residual first component from the separated gaseous second component fraction by scrubbing the second component at elevated pressure with a solvent (e.g. methanol) in a scrubber. In examples, the method further includes one or more steps of warming and expanding the gaseous second component fraction using at least one heat exchanger to exchange heat with a process stream and at least one turbo-expander capable of recovering mechanical work. The process described is highly energy efficient and is especially useful in hydrogen power plants, Integrated Gasification Combined Cycles (IGCC) and for sweetening sour natural gas.
