<p>PURPOSE:To enhance the oxygen absorption efficiency of a regenerating apparatus for reducing the size of the apparatus and to reduce the clogging of sulfur as compared with a packed tower system, by using an oxygen-enriched gas for regeneration of a desulfurizing soln. in wet desulfurizing hydrogen sulfide contained in a coke oven gas and spraying the desulfurizing soln. and the above gas from a two-fluid nozzle. CONSTITUTION:A coke oven gas 1 is led to an absorption tower 2, where hydrogen sulfide is removed with a regenerated desulfurizing soln. 3. The absorbing soln. 4 into which hydrogen sulfide has been absorbed is fed through an intermediate tank 5 into a regenerating tower 7. In the regenerating tower 7, an oxygen- enriched gas 8 having an oxygen concentration of 25% or higher is blown into the tower from the bottom while the absorbing soln. 4 is fed to a spray pump 6o to spray it at each plate. A two-fluid nozzle is used as the spray nozzle.</p> |
