A six-month evaluation of the Chiyoda Thoroughbred 121 Prototype Process (CT-121) was conducted at the Scholz Electric Generating Station of Gulf Power Company. The 23-megawatt CT-121 prototype was modified from existing CT-101 process equipment at Scholz by Chiyoda International Corporation, a subsidiary of Chiyoda Chemical Engineering and Construction Company, Ltd. Chiyoda operated the prototype, and the Electric Power Research Institute and Southern Company sponsored technical evaluations of the prototype process performance and gypsum waste disposal options in the 1978-1980 time period. This pilot-scale evaluation indicates that the CT-121 scrubbing system is an attractive alternative to other available FGD technologies based on lime and limestone. The prototype scrubber at the Scholz plant operated reliably and efficiently, under a variety of test conditions, while treating flue gas from a coal-fired utility boiler. The process has the potential of reducing levelized costs by about 10%, compared to conventional limestone scrubbing. The major results are given.
