摘要
邻苯二甲酸二辛酯脱醇过程是一个复杂的传质传热过程,过程变量多,被控变量多,可操纵的变量也多,过程动态和机理复杂。通过物料平衡、热量平衡、相平衡3个方面对脱醇操作的稳定性进行了分析,实现了脱醇塔各工艺参数的控制。
The dealcoholization process of phthalate dioctyl is a complex mass and heat transfer process, which fea- tures numerous process variables, controlled variables, controllable variables and complicated dynamics and mecha- nisms. The stability of dealcoholization operation was analyzed through three aspects, including material balance, heat balance and phase equilibrium and the control of all process parameters of the Dealcoholization Tower was realized.
