干式减压蒸馏中的真空技术

Vacuum technology of The dry type reduced-pressure distillation

减压塔采用干式减压蒸馏可提高原油拔出率。本文介绍适用于干式减压蒸馏的特殊结构真空抽气设备。

Adopting the dry type reduced-pressure distillation we can increase the rate of pe roleum distillate of reduced-pressure tower.This paper introduced a new type and special structured vacuum pump unit suitable for dry type reduced-pressure distillation.
