The new liquid distributor has been already applied in revamping of the washing zone in crude vacuum distillation tower 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 vacuum distillation tower 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。

Deep vacuum distillation, being restricted by operating conditions such as the heat stability of crude and the vacuity of vacuum tower etc., is a complicated system engineering.

减压蒸馏深拔受原油热稳定性和减压塔真空度等操作条件的制约，是个复杂的系统工程。
