    摘要: Flue gas processing is described. A circulating dry flue gas desulfurization (DFGD) scrubber is positioned upstream of a wet flue gas desulfurization (WFGD) scrubber. Flue gas temperature and humidity is controlled. Reagent use is monitored and controlled. The DFGD scrubber is controlled without concern for sulfur dioxide absorption and thus reagent utilization is controlled based on the goal of removing one or more of: sulfur trioxide and/or other acid gases. In some 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 is followed by the WFGD scrubber that removes sulfur dioxide and mercury, to achieve a high degree of pollutant removal at a low operating cost as compared to some other systems. WFGD scrubber liquid waste is sent to the circulating DFGD scrubber and used for temperature and/or humidity control purposes.

    摘要: An absorbing tower is provided in its side wall with a gas entrance for introducing a combustion exhaust gas into the absorbing tower, and an absorbing liquid is sprayed from the nozzles of a spray header into the exhaust gas introduced to rise from the gas entrance. A trough is arranged in the side wall of the absorbing tower and above the gas entrance, and a nose having a horseshoe shape in a top plan view and extending into tower is disposed in the tower side wall portion of the gas entrance other than the portion arranging the trough and at the same or at substantially the same height as the portion of the trough. The absorbing liquid, which is sprayed from the nozzle and drops along the absorbing tower wall portion, is rescattered to the center portion of the absorbing tower excepting the entrance of the absorbing tower, so that the gas-liquid contact efficiency is improved while suppressing an increase in pressure loss, thereby to prevent the drift of the gas at the tower wall portion.

    摘要: A flue gas desulfurization process and system that utilize ammonia as a reactant, and in which any hydrogen sulfide and/or mercaptans within the ammonia are separated during the desulfurization process so as to prevent their release into the atmosphere. The process and system entail absorbing acidic gases from a flue gas with a scrubbing media containing ammonium sulfate to produce a stream of scrubbed flue gas, collecting the scrubbing media containing the absorbed acidic gases, injecting into the collected scrubbing media a source of ammonia that is laden with hydrogen sulfide and/or mercaptans so that the injected ammonia is absorbed into and reacted with the collected scrubbing media, stripping the hydrogen sulfide and/or mercaptans from the collected scrubbing media by causing the hydrogen sulfide and/or mercaptans to exit the collected scrubbing media as stripped gases, and collecting the stripped gases without allowing the stripped gases to enter the stream of scrubbed flue gas.
