摘　　要：分析了常减压塔底管道及换热器结垢和腐蚀的机理 ,包括沥青质、腐蚀产物的沉积以及自由基聚合反应 ,其中沥青质沉积是主要原因 ,腐蚀主要由硫化物高温分解产生活性硫而引起的 ,根据结焦和腐蚀机理研制开发了VAF 1阻垢缓蚀剂。动态和静态评价以及腐蚀性能评价结果表明 ,VAF 1阻垢缓蚀剂阻垢率达 89.2 % ,缓蚀率达91.2 %。Mechanisms of coking and corrosion of pipes and heat exchangers for the atmospheric and vacuum residua tower,including deposition of asphaltene and corrosion product,free radicals polymerization,were analyzed.Asphaltene deposit is the main cause of coking and corrosion results from active sulfur by sulfide decomposition.The VAF 1 coking and corrosion inhibitor was developed according to the mechanisms.Both static and dynamic evaluation indicated that its coking and corrosion inhibiting rates are 89.2% and 91.2%,respectively.
