Behrens, G P

An experimental laboratory study testing the effectiveness of adipic acid in the Chiyoda Thoroughbred 121 FGD system has been sponsored by the Electric Power Research Institute. Additionally, economic calculations for the cost effectiveness of usng adipic acid in a commercial scale CT-121 FGD system have been performed. The results of this study indicate that although adipic acid can increase the SO/sub 2/ removal capability of the CT-121 system, it is not an economically attractive process improvement. This result is due to the CT-121 process chemistry which minimizes limestone consumption and sludge volume without the need of adipic acid. These two areas realize major cost savings when adipic is used in a conventional limestone FGD system. The economic evaluation indicates even though a lower gas-side pressue drop is achieved when adipic acid is used, the savings in electrical costs are insufficient to offset the cost of adipic acid.
