Abstract

PURPOSE: To perform dry type stack gas desulfurization economically by using a fine desulfurizing agent produced in the circulation system of the agent in an adsorption tower and a desulfurization tower wherein said desulfurizing agent consisting of coat as raw material and being used, as a reducing agent for gaseous SO2.
CONSTITUTION: The waste combustion gas 4 of a boiler 100 joins with flow 5 and SOx contd. Therein is removed in an adsorption tower 200. The desulfurizing agent having adsorbed sulfuric acid is heated, desorbed and regenerated in a desorption tower 300. The regenerated desulfurizing agent is removed of powdery material in a classifier 900, and is circulated to the tower 200. The powdery material is used for the reduction of the desorbed gas in a reducing tower 400 and the reducing gas 14 contg. S2, CO2, CO, H2, H2S is cooled in a condenser 500. The S2 fraction is recovered into a storage tank 800. The remaining gas 16 forms sulfur by reacting with the SO2 from the flow 19 which is part of the desorbed gas of the flow 9 in a claus reaction tower and is recovered via a condenser 700 into the tank 800. The uncondensed gas in the condenser 700 is joined from the flow 5 into the waste combustion gas 4.
