| titleOfInvention | Use of potassium polyphosphate in so{11 {0 recovery from stack gases |
| abstract | Recovery of sulfur dioxide from stack gas consisting of scrubbing the gas with potassium polyphosphate solution to form a slurry of crystallized potassium pyrosulfite. The potassium pyrosulfite is regenerated for further pickup of sulfur dioxide by (1) heating the slurry directly, (2) separating the potassium pyrosulfite and treating it in a reflux stripper, (3) heating the potassium pyrosulfite in solid form, or (4) heating solid potassium pyrosulfite to drive off one-third of the sulfur dioxide and reducing the remaining two-thirds to form hydrogen sulfide, the sulfur dioxide and hydrogen sulfide being reacted to form elemental sulfur. |
