摘要
中国石化镇海炼油化工股份有限公司Ⅲ套常减压蒸馏装置因长期加工中东轻质高硫原油,导致常顶系统腐蚀十分严重,换热器管束泄漏频繁。文章对引起Ⅲ套常减压蒸馏装置低温系统腐蚀的原因进行了深入分析,对近几年在工艺防腐蚀、材料防腐蚀方面所采取的措施进行了总结,并提出了下一步改进措施。
The overhead system of No. Ⅲ atmospheric distillation tower of SINOPEC Zhenhai Refining ＆ Chemical Co., Ltd experienced severe corrosion and frequent heat exchanger failures due to the processing of Mid-east high sulfur crudes. The causes of corrosion of low temperature system are analyzed and the corrosion protection measures adopted in the recent years in respect of process corrosion prevention and material corrosion protection ere are summarized. The improvement measures are suggested for the future operation.
