This report presents the results of an evaluation of the Chiyoda Thoroughbred 121 (CT-121) flue gas desulfurization process which was sponsored by the Electric Power Research Institute (EPRI) and the State of Illinois Department of Energy and Natural Resources. The objectives of this program were to evaluate the performance and to document the operating and maintenance costs of the CT-121 process under commercial operating conditions. Tests were performed using a 40 MW equivalent CT-121 process installed at the University of Illinois steam power plant. Performance tests were conducted to confirm Chiyoda's guarantees of SO{sub 2} removal efficiency, particulate emissions, limestone utilization and gypsum byproduct quality. Parametric tests investigated the effects of overflow pH, gas sparger depth, slurry density, and filter cake wash rate on SO{sub 2} removal, gypsum quality, and overall system performance. Results show that the process is able to meet performance guarantees, and that the overflow pH and gas sparger depth had the largest impact on SO{sub 2} removal efficiency. Results are also compared to those from a previous CT-121 demonstration conducted at Gulf Power's Scholz Station by EPRI and Southern Company Services. Operating and maintenance costs are presented in $/kW-hr. 5 refs., 27 figs., 33 tabs.
