Catalytic cracking flue gas desulfurization technology can fully realize the dis-charge of flue gas purification and achieve emission standards.However,due to existence of the corrosive medium,corrosion problem happens in the desulfurization absorber tower of many cat-alytic desulfurization devices.This article analyzes the corrosion of a desulfurization absorber tower in a compang and identifies the causes of corrosion.The combined action of changes in the operating mode after reconstruction of the desulfurization absorber tower and local defects of the materials causes the corrosion.By strictly controlling the manufacturing process of composite plate,improving the nozzle structure of outlet distributor of circulating pump and moving up the ammonia water distributor,the desulphurization tower has not been corroded again.
