Cocurrent scrubber evaluation: TVA's Colbert lime-limestone wet-scrubbing pilot plant
The Tennessee Valley Authority (TVA) is actively engaged in a pilot plant program to develop and/or evaluate wet-scrubbing processes for removing sulfur dioxide (SO/sub 2/) from boiler flue gas. The physical size and general arrangement of flue gas scrubbing systems have a major impact on capital investment and operating cost, as do potential operating and maintenance advantages inherent to some systems. The equipment configuration for a cocurrent scrubber reflects some of these advantages. EPRI funded TVA to perform preliminary screening tests at TVA's 1 MW pilot plant (Colbert Steam Plant) to develop operating data on the cocurrent design for use in designing and operating a 10 MW prototype cocurrent scrubber at TVA's Shawnee Scrubber Test Facility. Results of Colbert tests showed excellent sulfur dioxide removal efficiencies, generally greater than 85%, low pressure drop, and high particulate removal efficiencies. This report covers these screening tests. The results indicate that commercial application of the cocurrent scrubber concept may save substantial capital investment by reducing the number of scrubber modules and auxiliary equipment. These evaluation tests provided the basis for the design and construction of the 10 MW cocurrent scrubber at the Shawnee Facility. Operation of this scrubber began in August 1978 to develop the scale-up similarities and differences between the Colbert test program (1 MW) and the Shawnee test program (10 MW). It also demonstrated the practicality and reliability of the 10 MW prototype. Detailed results of the prototype test series will be available in late 1979.
