The report describes test results from a lime/limestone scrubbing test facility for removing SO2 and particulates from flue gases. The facility consists of three parallel scrubbers--a venturi/spray tower, a Turbulent Contact Absorber (TCA), and a marble-bed absorber--each able to treat a 10 Mw equivalent (30,000 acfm) of flue gas from a coal-fired boiler at TVA's Shawnee Station. Limestone factorial tests were conducted on all three scrubbers to determine the effects of the independent variables on SO2 and particulate removal. Lime and limestone reliability tests were conducted on the venturi/spray tower and TCA systems, respectively, to demonstrate long-term reliability, primarily of the mist elimination systems. The TCA mist elimination system (a Koch Flexitray in series with a chevron mist eliminator) has remained essentially clean over a 1000 hour period at a superficial gas velocity of 8.6 ft/sec. A recent test of the spray tower mist elimination system (a chevron mist eliminator with provision for underside and topside washing) at a superficial gas velocity of 6.7 ft/sec indicated that long-term operability of this system may be expected.
