REMOVING SULPHUR OXIDES FROM A FLUID STREAM |
摘要 |
A process for removing sulphur oxides from a fluid stream,such as flue gas, that comprises 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 where by 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. The process mitigates absorbent degradation problems caused by sulphur dioxide and oxygen in flue gas. |
