This thesis discusses the corrosion and scaling mechanism in the pipeline system of high pressure air coolers in wax oil hydrogenation plant and gives an introduction to the industrial application situation of JYH-3000 type polysulfide inhibitor in wax oil hydrogenation plant of Tianjin Petro-chemical Company. Result shows that JYH-3000 type polysulfide inhibitor possesses favorable effect to prohibit sulfide and cyanide corroding to air coolers and in this way it increases the working efficiency of air coolers and guarantees the plant’s stable running.
