以丙酮回收塔为例,研究ChemCAD在精馏塔动态模拟中的应用,建立带有控制系统的动态精馏模型。分析精馏塔操作条件、进料状况等发生变化时,精馏塔在当前控制方案下的动态响应过程,得到并分析常规PID控制方案在精馏塔操作中存在的问题,为进一步剖析精馏过程特性,确定合适的优化及控制方案提供参考。 Taking acetone recovery column as an example, the application of ChemCAD in the dynamic simulation of distillation column was studied, and a dynamic distillation model with control system was established. Analysis of the distillation column operating conditions, feed conditions, etc., the distillation column in the current control program under the dynamic response process, the conventional PID control program in the operation of the distillation column problems, in order to further analyze the distillation Process characteristics, to determine the appropriate optimization and control programs provide a reference.
