Abstract: A certain steel plant employs the medium and low temperature catalytic hydrolysis of organic sulfur and wet absorption of inorganic sulfur processes in desulfurization of blast furnace gas.However,some problems are exposed during actual operation,such as entrainment of gas,jumping and stopping of circulating pump,outflow of catalyst and occasional over-standard of sulfur at outlet.Through combing and analyzing the causes of the problems one by one,and the optimization measures are adopted to ensure the normal operation of the system and the emission of tail gas up to standard on the basis of ensuring the same construction period and minimizing the economic cost.
