Application of combination column in cyclohexene extractive distillation unit

Wu Jimin (Henan Shenma Nylon Chemical Co Ltd, Pingdingshan 467013,China)  
The cyclohexene separating column was reformed by using combination column and new process.After reforming,the top cyclohexene in separating column decreased from 6.5% to 4.0%,the top cyclohexene of recovery column decreased from 3.5%~4.8% to 2.5%,the purity of cyclohexene increased from 95% to 97%.
