Title: Aqueous carbonate process for flue gas desulfurization (FGD) a status report
Abstract: Recent design activities include the Bechtel Corp. contract awarded to Rockwell International Corp.'s Atomics International Division and Wheelabrator-Frye Inc. for the construction, by June 1981, of a soda ash-based open-loop FGD system to treat 1,960,000 cu ft/min of flue gas from the 410 Mw lignite-fired Coyote Power Station plant in Mercer County, N.D., now under construction. A program jointly sponsored by the Empire State Electric Energy Research Corp. and EPA, is also under way to design, build, test, and operate a 100 Mw, second-generation FGD demonstration plant, based on the closed-loop system, at Niagara Mohawk Power Corp.'s Tonawanda power station; cost predictions for 500 and 1000 Mw plants will also be generated. The original Rockwell International Corp. aqueous carbonate FGD process with regeneration of the scrubbing product (sodium sulfite and sulfate) and a pilot plant and test results for the open-loop (nonregenerative) ''dry scrubbing'' version of the process (Abstract No. 26-30549) are described.
