摘要:

介绍了负压粗苯蒸馏技术的主要特点。原料不经管式炉加热直接进粗苯塔,粗苯塔与再生塔共用1台加热炉,粗苯塔采用高效抗堵塔盘,装置操作灵活可靠。与常压直接蒸汽蒸馏工艺相比,具有节能、环保、操作稳定等优点。

Abstract:

This paper introduces crude benzol vacuum distillation process,i.e.the feedstock directly enters the crude benzol column with high efficiency blockage-free trays,sharing one tubular furnace together with regenerator,which can be in flexible and reliable operation.Compared with direct atmospheric steam distillation,this process has advantages of energy-saving,environmental protection and stable operation.
