Dry SO/sub 2/ scrubbing at Antelope Valley, ND, power station
Pilot-plant studies of the Niro Atomizer A.S./Joy Manufacturing Co. soda ash or lime-slurry dry desulfurization system at a Minnesota powerplant preceded Basin Electric Power Cooperative's choice of the process for a 440 MW, lignite-fired unit at its Antelope Valley station near Bismarck, ND. The pilot-plant work showed that dry scrubbing would meet the EPA New Source Performance Standards for SO/sub 2/ removal and that the system would be simpler to operate, need less complex equipment, hence, more available than a wet scrubber. The $47 million advantage of the dry over a wet system is site-specific. Some of the features of the Joy/Niro system are the recycle of a portion of the spent chemicals and fly ash to the fresh feed, thereby saving time; the use of a single rotary atomizer centered in the spray dryer absorber; the compound gas disperser design; and the Joy stepped tube sheet baghouse design.
