Method of scrubbing sulfur dioxide from waste gas to product potassium thiosulfate |
| abstract |
A method of wet-scrubbing a waste gas containing sulfur dioxide (SO 2 ) to produce potassium thiosulfate. The wet-scrubbing facility includes multiple horizontally disposed stages where a preceding stage passes partially-scrubbed waste gas to a succeeding stage. Each stage has a scrubber mechanism to scrub waste gas with circulating fluid that progressively reduces SO 2 in the waste gas before atmospheric discharge. The scrubber mechanism may optionally include a packing material to facilitate absorption of SO 2 by the fluid, a sump disposed at the output of the stage to receive fluid as it drains from the packing, and a circulation pump to circulate fluid from the sump to its packing and to cascade at least a portion of the fluid back to a preceding stage. A portion of the fluid is extracted and reacted in a reaction vessel with a cation to produce potassium thiosulfate. |
