  • Air pollution control process
    Patent number: 4147755
    Abstract: Gases containing SO.sub.2 from a furnace are contacted in the scrubbing zone of a scrubber with an aqueous scrubbing medium containing Ca(OH).sub.2 whereby sulfites are formed. The Ca(OH).sub.2 additive is at least partially the Ca(OH).sub.2 sludge produced in the manufacture of acetylene from CaC.sub.2. This sludge contains constituents which retard or inhibit the oxidation of sulfite to sulfate to thereby reduce the possibility of sulfate scaling in the system.
