摘　　要：针对中国石油辽阳石化分公司3.5Mt/a常压蒸馏塔塔顶空冷器频繁发生腐蚀泄漏的现状,分析其腐蚀泄漏原因,并采取相应措施后,脱后原油的盐含量(以NaCl计)低于3mg/L的控制指标,且投用后6台常顶空冷器未出现过泄漏,达到了预期的效果。Aimed at the current situation of frequent corrosion leakage in air cooler on top of 3.5 million t/a atmospheric distillation column in PetroChina Liaoyang Petrochemical Company, corrosion leakage causes were analyzed. Salt content of the crude oil was less than 3 mg/L after the removal treatment, no leakage occurred in the six air coolers on top of the atmospheric distillation column, expected effect was obtained.
