Patent ID: 8691171

Claim:
A process for removing sulphur oxides from a fluid stream comprising a) providing a non-aqueous absorption liquid containing at least one hydrophobic amine, the non-aqueous absorption liquid being incompletely miscible with water; b) treating the fluid stream in an absorption zone with the non-aqueous absorption liquid to transfer at least part of the sulphur oxides into the non-aqueous absorption liquid and to form a sulphur oxide-hydrophobic amine-complex; c) causing the non-aqueous absorption liquid to be in liquid-liquid contact with an aqueous liquid whereby at least part of the sulphur oxide-hydrophobic amine-complex is hydrolyzed to release the hydrophobic amine and sulphurous hydrolysis products, and at least part of the sulphurous hydrolysis products is transferred into the aqueous liquid; d) separating the aqueous liquid from the non-aqueous absorption liquid.
