摘要:

HPF脱硫工艺脱硫效率波动较大,脱硫系统存在吸收塔循环喷淋密度小、氨硫比低、脱硫液中两副盐含量高等问题。通过提高吸收塔循环喷淋密度、增加提盐装置、降低脱硫系统温度等措施,脱硫效率显著提高,脱硫系统运行逐渐稳定。

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.
