本文全面的调查和分析了兰州石化公司连续重整装置预处理系统开工之初就发生严重腐蚀的情况,发现腐蚀原因主要是原料中的有机硫与有机氯,在加氢过程中,反应生成硫化氢和氯化氢,冷凝时溶解于水,形成强烈的电化学腐蚀环境,发生NH4Cl垢下腐蚀、湿H2S腐蚀、HCl+H2S+NH3+HO腐蚀及互相之间的藕合,造成设备的快速严重腐蚀。 In this paper, a comprehensive investigation and analysis of Lanzhou Petrochemical Company continuous reformer pretreatment system started serious corrosion situation, found that the main cause of corrosion is the organic sulfur and organic chlorine in the raw material, in the hydrogenation process, the reaction of sulfide Hydrogen and hydrogen chloride, dissolved in water condensation, the formation of a strong electrochemical corrosion environment, the occurrence of NH4Cl scale corrosion, wet H2S corrosion, HCl + H2S + NH3 + HO corrosion and mutual coupling, resulting in rapid serious corrosion of equipment .
