two-stage device for washing of sulphur tail gas, in particular from coal-fired power stations

摘要

in the ablution of sulfurous gases, in particular from coal-fired power stations, with kalziumoxydhaltigen or kalziumhydroxydhaltigen washing liquids in the kreislaufverfahren occur in significant proportions of hydrogen chloride and hydrogen fluoride in the flue gas may be difficult through chloranreicherung in the circulating liquid for washing.this will add a waschstufe prevents the hydrogen chloride and hydrogen fluoride by means of appropriate in clear water from the flue gas are separated. at the same time, a desired cooling of the gas.
