Abstract: A process for treating a gas stream comprising hydrogen sulphide, the process comprising the steps of: (i) mixing a first gas stream comprising hydrogen sulphide with a second stream comprising sulphur dioxide to produce a combined stream, whereby elemental sulphur is produced by a reaction between the hydrogen sulphide and the sulphur dioxide; (ii) removing elemental sulphur, and optionally water, from the combined stream; and (iii) oxidizing at least some of the elemental sulphur to form sulphur dioxide for use in the second stream, wherein, the reaction is conducted at a temperature of from 15 to 155° C. and a pressure of at least 3 MPa.

Abstract: A method for removing impurities from a feed air gas stream prior to the stream being fed to a cryogenic distillation unit. The feed air gas stream contacts an ionic liquid which adsorbs the impurities from the air. The method can use one or more beds such as in pressure swing adsorption processes.
