丙酮汽提塔系统的工艺改造

Technical Renovation of Acetone Stripper System

原醋酸回收系统中丙酮汽提塔脱丙酮的效率很低，损失大量己烷。改造后的脱丙酮系统脱丙酮效率提高，己烷损失减少，每年节省成本４０多万元，并延长了设备的寿命。介绍了丙酮汽提塔系统的工艺改造过程。

After renovation, the acetone stripper raises its efficiency, Which was rather low in the original acetic acid recovery system for removing acetone. As the loss in hexane is reduced, the cost can be cut down mom than 400 thousand RMB yuan annually, and the service life of facilities can be prolonged. The process for renovating acetone stripper system is described.
