| Abstract: | The advanced and intelligent monitoring technologies were used to real-time monitor continuous process designed for the refining of high purity acetonitrile where the pressure-swing azeotropic distillation was applied for high product purity and yield.In order to improve the steady-state accuracy and adaptive ability of control system,an adaptive intelligent fuzzy-Smith control strategy was employed by the temperature control system with big inertia and pure time delay.Industrial applications show a stable process and efficient control system and obvious economic benefits. |
