| Abstract | Flue gas processing is described. A circulating dry flue gas (76) Inventor: Edward Bialkin, Lebanon, NJ (US) desulfurization (DFGD) scrubber is positioned upstream of a wet flue gas desulfurization (WFGD) scrubber. Flue gas tem perature and humidity is controlled. Reagent use is monitored and controlled. The DFGD scrubber is controlled without (21) Appl. No.: 13/051,685 concern for Sulfur dioxide absorption and thus reagent utili Zation is controlled based on the goal of removing one or more of Sulfur trioxide and/or other acid gases. In some (22) Filed: Mar. 18, 2011 embodiments the circulating DFGD scrubber removes the majority of sulfur trioxide, HCL, and/or HF from the flue gas stream supplied to the DFGD scrubber. The DFGD scrubber Publication Classification is followed by the WFGD scrubber that removes sulfur diox ide and mercury, to achieve a high degree of pollutant removal (51) Int. Cl. at a low operating cost as compared to some other systems. BOLD 53/48 (2006.01) WFGD scrubber liquid waste is sent to the circulating DFGD BOI. 8/00 (2006.01) scrubber and used for temperature and/or humidity control BOLD 53/68 (2006.01) purposes. |
