The report gives results of advanced program tests on a prototype lime/limestone wet-scrubbing SO/sub 2/ and particulate removal facility at TVA's Shawnee Power Station. With the objective of achieving reliable mist eliminator operation, a venturi/spray tower was operated with lime slurry, and a Turbulent Contact Absorber (TCA) with limestone. Each had 30,000 acfm (10MW equivalent) flue gas capacity. The venturi/spray tower system was maintained essentially clean in an 823-hour run at 8.0 ft/sec gas velocity and 8% slurry solids (the 3-pass, open-vane chevron mist eliminator was intermittently washed on both topside and underside with makeup water). The TCA system was operated successfully in an 1835-hour run at 8.6 ft/sec gas velocity and 15% slurry solids (the mist elimination system consisted of a Koch Flexitray in series with a 6-pass, closed-vane chevron mist eliminator, both with underside wash). Both scrubber systems operated with better than 99% particulate removal efficiency and with outlet grain loadings of 0.01 to 0.03 grains/scf. A correlating equation is presented for TCA pressure drop tests. (GRA)
