EPA alkali scrubbing test facility: Summary of testing through October 1974. Final report

Technical Report ·
OSTI ID:7343844
Test results are described from a lime/limestone scrubbing test facility for removing SO/sub 2/ 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 SO/sub 2/ 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.
