从轻质油中回收环氧环己烷和正戊醇的方法及装置
摘要：
本发明提供一种从轻质油中回收环氧环己烷和正戊醇的装置，包括开环反应釜、与开环反应釜连通的分离提纯装置、与分离提纯装置连通的闭环反应塔及分别与闭环反应塔和开环反应釜连通的闪蒸罐。本发明还提供一种从轻质油中回收环氧环己烷和正戊醇的方法。上述从轻质油中回收环氧环己烷和正戊醇的方法及装置，通过将部分闭环反应得到的循环盐水闪蒸后用作开环反应所需的盐水，能够使盐水浓度稳定维持在18%~22%，工艺稳定。
摘要（英）：

The invention provides an apparatus for recycling epoxycyclohexane and n-pentanol from light oil, comprising a ring-opening reaction kettle, a separation and purifying device communicated with the ring-opening reaction kettle, a ring-closing reaction column communicated with the separation and purifying device, and a flash tank communicated respectively with the ring-closing reaction column and the ring-opening reaction kettle. The invention also provides a method for recycling epoxycyclohexane and n-pentanol from light oil. According to the method and apparatus for recycling epoxycyclohexane and n-pentanol from light oil, the circulatory saline generated in ring-closing reaction is partially flashed and used as saline required for ring-opening reaction, the concentration of the saline can be maintained to 18-22%, and the process is stable.
