摘要 |
Disclosed is method for removing carbonyl sulphide and/or carbon disulphide from a sour gas stream. The method comprises subjecting the gas stream to simultaneous contact with an absorption liquid, such as an aqueous amine solution, and with a catalyst suitable for hydrolyzing carbonyl sulphide and/or carbon disulphide. To this end, the invention also provides a reactor system wherein both an absorption liquid and a catalyst are present. In a preferred embodiment, the catalyst is a heterogeneous catalyst present on or in an absorption column, either coated on the trays of a column with trays, or contained in the packing of a packed column. |

1. A method for removing carbonyl sulphide and/or carbonyl disulphide from an untreated natural gas stream comprising subjecting the gas stream to contact with an absorption liquid so as to provide an absorbed gas-containing liquid, and bringing the absorbed gas-containing liquid in contact with a catalyst suitable for hydrolyzing carbonyl sulphide and/or carbonyl disulphide. |
