vacuum tower

Some measures to improve extraction ratio of combustible vacuum tower were introduced in this paper, which included the renovation on the traditional practice of wet vacuum distillation, the reduction of the pressure drop of the tower, the stablization and improvement of the vacuity.

本文讨论了通过改变传统的湿式减压蒸馏操作、降低塔的压力降、稳定和提高真空度等提高燃料型减压塔拔出率的措施。

The problems of traditional hot wall transfer line of vacuum tower, such as more heat displacement of the horizontal pipe at low velocity, large pushing force on the tower support and severe sulfur corrosion, etc., are analyzed.

剖析了传统的热壁减压塔转油线存在的低速段水平直管热位移量大，对减压蒸馏塔和支架的推力大，硫腐蚀严重等问题。

The viscosity index of distillate oil from the 3rd side line of vacuum tower is very low. After being treated by hydrogenation, the viscosity index reaches 40~ 50, and can be used for modulating diesel oil of grade CA.

减三线馏分油粘度指数很低，加氢处理后其粘度指数达40～50，可用于调制CA级柴油机油。
