新型传质分离装置在洗脱苯中的应用

Application of the New Mass Transfer Separation Facility In the Benzene Wash and Removal Plant

传质分离装置的选型关系着粗苯回收工段的关键设备洗苯塔、脱苯塔的效率、能耗等。评述了各种常见的传质分离装置的优缺点及选择依据,分析了在洗苯和脱苯工艺过程中的传质分离特点。结合工艺参数介绍了新型高效CJST塔板,该塔板具有气液相表面积大、液相中分子传递速率快、通过气液相高速碰撞湍流可加强相界面更新等特点,并指出在操作中要注意控制脱苯塔富油进塔温度。实践证明,CJST塔内件的使用,提高了粗苯回收率。

With China′s rapid economic development,energy crisis causes high prices of the coking coal,and the coking enterprises face the problem of cost rise.We must attach importance to recovery of chemical production.Recovery of crude benzol from the coke oven gas in an efficient way is an important work for the optimization of the coking plant technology.In this paper Through reviewing the advantages and disadvantages of all types of the mass transfer device and basis selection theory,we analyze the mass transfer...
