针对企业反应过程生成甲醇副产物回收工艺进行设计改造。基于超重力旋转精馏床具有传质效率高、设备体积小的优点，将超重力精馏床与反应釜耦合，改变传统反应过程甲醇回收方式。改造后工艺可实现反应过程副产物甲醇与水的分离，给企业节省了大量能耗和管理成本，比传统甲醇回收工艺具有明显优势。

The recovery process of methanol by-product generated in the reaction process in a certain company is designed and renovated.HIGEE rotating distillation bed, due to its advantages of high mass transfer efficiency and small equipment volume, can combine with the reaction kettle to change traditional solvent recovery method in the reaction process.Through theoretical calculation and experiment, this process after renovation can achieve the separation between byproduct methanol and water, which help the company save a lot of energy consumption and management cost, and exhibits obvious advantages over traditional process.
