OSTI ID:6507631
; ;
Sulfur recovery from smelter and like exhaust gases by refrigerating the exhaust gases and removal of most of the contained water and SO/sub 2/ as a liquid phase, the removal being by liquid spray scrubbing, utilizing previously recovered water, after SO/sub 2/ removal therefrom, as the scrubbing liquid is described. Single or plural stages of refrigeration and liquid phase separation can be employed. The SO/sub 2/ is removed by combining thereof with the cool scrubbing water and is recovered by chemical treatment to neutralize and precipitate such as a sulfite salt.
