This paper described the regenerative process and the open-loop dry scrubbing process, the test programs and the status of both processes. There were seven major process steps in the regenerative ACP. These were: (1) contacting the flue gas with sodium carbonate solution in the spray dryer scrubber; (2) collecting the dry products of the scrubbing step; (3) reducing the sodium sulfite and sulfate to sulfide with carbon in the molten state; (4) quenching the reduced molten salt mixture with water; (5) filtering out ash and unreacted carbon; (6) carbonating the sulfiding solution with a CO/sub 2/-rich gas to strip off H/sub 2/S; and (7) producing elemental sulfur from the H/sub 2/S. During 1977, a pilot plant scrubbing test facility conducted tests which provided comprehensive data in the two-stage, open-loop system. Twenty-seven different conditions using sodium carbonate were tested. The open-loop and closed-loop systems were described. 3 figures.
