Shawnee Test Program. TVA Shawnee Test Facility. Final technical report, December 26, 1980-May 31, 1981
Tests were conducted on train 100 (spray tower) at the Shawnee Test Facility between December 26, 1980, and May 30, 1981. Objectives were, respectively, to demonstrate the ability to operate a limestone scrubber on flue gas from high-sulfur coal using adipic acid slurry additive and forced oxidation long term without scale buildup at >90% SO/sub 2/ removal; to obtain factorial test data on a limestone spray tower system using forced oxidation and adipic acid; to evaluate the effect of changing spray header height and direction in a spray tower on SO/sub 2/ removal; and to determine if sodium thiosulfate is effective as a slurry additive to inhibit sulfate scale buildup. Operating conditions were determined wherein acceptable SO/sub 2/ removal (90 percent minimum) could be obtained over a three month period using limestone and adipic acid with forced oxidation. Quantitative relationships between spray header height, spray direction, and SO/sub 2/ removal were obtained for a spray tower having multi-level spray headers. Sodium thiosulfate added at a rate to maintain a 250 ppM level in the scrubber slurry under specific operating conditions was found to inhibit crystallization of sulfate from solution and to remove sulfate scale buildup already in place.
