| titleOfInvention | System for Rearrangement Reaction Solvent Recovery |
| abstract | The utility model relates to the production field of caprolactam, and discloses a system for recovering a solvent in a rearrangement reaction. The system comprises a horizontal reactor and a recovery tower. The horizontal reactor is provided with a maturation chamber and a plurality of rearrangement chambers. The rearrangement chambers are arranged in sequence along the horizontal direction, and adjacent rearrangement chambers are separated by partitions, the maturing chambers are arranged downstream of the most downstream rearrangement chamber and separated by The bottom is respectively provided with cyclohexane and cyclohexanone oxime mixed liquid inlet, the most upstream rearrangement chamber is provided with oleum inlet, and the bottom of the aging chamber is provided with product outlet, the height of each partition is the same or different but can Make the material overflow from the upstream to the downstream rearrangement chamber or the curing chamber; the recovery tower is located above the curing chamber, and is used to recover the cyclohexane discharged from the curing chamber. The system avoids the resistance loss of the rearranged liquid in the pipeline and saves energy. |
