| 摘 要： | 采用新型填料塔技术和新的工艺流程,对原环己烯分离塔系统进行改造,改造后环己烯分离塔塔顶环己烯从6.5%下降到4.0%,环己烯回收塔塔顶环己烷从3.5%～4%下降到2.5%,环己烯纯度从95%提高到97%以上,本次改造提供了一种萃取精馏塔扩能改造的新思路--更改部分工艺,提高提馏段效率.

| Abstract: | In this paper, a new - style packed technology and a new process were used to reform the separating - column - system of cyclohexene. The concentration of cyclohexene was reduced to 4.0% from 6.5% at the top of cyclohexene - separating - column and the concentration of cyclohexane was reduced to 2.5% from 3.5% -4% at the top of cyclohexene - recovery -column,while the purity of cyclohexene was raised from 95% to 97% or above. The paper gave some clues to the extractive - distillation - column in capacity expansion, such as improving partial process and enhancing the efficiency of stripping section. |
