Abstract:

This paper described a solution to the problems of HPF desulfurization process, such as big fluctuation of desulfurization efficiency, low intensity of circulating spray in absorber, low ammonia sulfur ratio and high secondary salt in desulfurizer liquor, etc. so that  remarkable desulfurization efficiency and increasing stable operation of the desulfurization system can be achieved by means of improving absorber spray intensity, adding salt abstraction device and reducing the temperature of desulfurization system, etc.
