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 method of separating a carbon-dioxide-rich liquid stream from a synthesis gas including carbon dioxide and hydrogen, includes carrying out a first cooling step to cool a synthesis gas feed stream using at least one heat exchanger such that a first two-phase mixture is formed. The first two-phase mixture is passed at a first pressure and a first temperature to a first separator and a first separation is carried out to separate the first mixture into a first CCVrich liquid stream and a H2-Hcli gas stream. The H2-rich gas stream is pressurised and a second cooling step is carried out to cool the H2-rich gas stream using at least one heat exchanger such that a second two-phase mixture is formed. The second mixture is passed at a second pressure and a second temperature to a second separator, the second pressure being higher than the first pressure and a second separation is carried out to separate the second mixture into a second CO2-rich liquid stream and a further H2-rich gas stream. Preferred examples further include the step of expanding at least one of the separated H2-rich vapour streams to recover mechanical work and/or to cool the H2-rich stream and subsequently using the expanded H2-rich stream as a coolant in the separation system.
