Abstract
The report describes and presents initial results of testing a prototype wet-lime/limestone scrubbing facility for removing SO2 particulates from flue gases. The facility consists of three parallel scrubbers--a venturi/spray tower, a Turbulent Contact Absorber (TCA), and a marbel-bed scrubber--each able to treat a 10-Mw equivalent (30,000 acfm) of flue gas from a coal-fired boiler at TVA's Shawnee Station. The short-term limestone tests, conducted at high scrubber inlet liquor pH (6.0-6.2), saw SO2 removals of 80 (venturi/spray tower and marble-bed scrubber) to 96% (TCA). Initial longer term tests were run at reduced stoichiometries to increase system reliability and limestone utilization. For the TCA, limestone utilization was 83% with SO2 removal of 80-85%. Operability and reliability of the scrubbers for these tests were good.
