A kind of cyclohexanone recovery and separation process and system |
| abstract |
The invention discloses a cyclohexanone recovery and separation process and system. The process includes: the cyclohexanone-cyclohexanol mixture from the front-end hydrolysis unit enters the light-removing tower as the feed of the light-removing tower; Hexanone; heavy components at the bottom of the delight tower enter the cyclohexanone tower, the top of the cyclohexanone tower produces cyclohexanone products, and the bottom of the cyclohexanone tower enters the cyclohexanone tower; the top of the cyclohexanone tower produces high concentration cyclohexanone Alcohol, cyclohexanol tower bottom heavy component impurity discharge device; liquid phase is extracted in the middle section of cyclohexanol tower, and used as the liquid phase feed of the primary cyclohexanone recovery tower; the bottom material of the secondary cyclohexanone recovery tower is mixed with The bottom material of the light-removing tower enters the cyclohexanone tower after mixing. The process of the invention can effectively reduce the material consumption in the separation process of cyclohexanone and improve the yield of cyclohexanone while ensuring the impurity removal efficiency. |
