The new liquid distributor has been already applied in revamping of the washing zone in crude vacuumdistillationtower with high temperature, small flowrate, dirt and easy-coking material.
新型液体分布器已应用到温度高、液量小、物系脏、易结焦的原油减压蒸馏塔洗涤段的改造中。

The excessive naphthenic acid corrosion of the vacuumdistillationtower was introduced. The corrosion mechanisms was explored and the corrosion-resistance of the 316L stainless steel was studied.
介绍了减压塔受环烷酸腐蚀的严重程度，探讨了腐蚀机理和应用316L不锈钢抗腐蚀的效果。
