摘　　要：常减压蒸馏装置作为炼油厂原油加工的龙头装置,其长周期稳定运行能力决定了炼厂是否能够“安稳长满优”运行.随着炼厂加工原油的劣质化趋势不断加重,常减压蒸馏装置,特别是常压塔顶系统低温部位的设备和管线,腐蚀现象尤为突出,已成为行业难题和痛点.文章剖析了常压塔顶系统腐蚀的根本原因,并从材料设计、工艺防腐、在线除盐、腐蚀监检测等方面多角度、系统性地阐述了腐蚀控制综合设计技术,提出了有效的防腐蚀策略,可为常减压装置的稳定运行提供有力保障.Atmospheric and vacuum distillation unit is the leading unit of crude oil processing in refineries.Its long-term stable operation capacity determines the safe,stable,long-term,full capacity and excellent operation of refineries.With the worsening trend of crude oil processing in refineries,the corrosion of equipment and pipelines in atmospheric and vacuum distillation units,especially in the low-temperature part of the atmospheric column top system,has become a difficult problem and pain point in the industry.This paper analyzes the root causes of corrosion of atmospheric column top system,systematically expounds the comprehensive design technology of corrosion control from multiple angles such as material design,process anti-corrosion,on-line desalination,corrosion monitoring and detection,and puts forward effective anti-corrosion strategies which can.ensure the stable operation of atmospheric and vacuum distillation unit effectively.
