For the actual distillation process with side reactor

a dynamic simulation system including control system is developed based on reasonable simplifying and assumptions.Some typical fault disturbances which induced the dynamic imbalance between the separation capability and reaction capacity

such as the disturbance of unreasonable feed flow ratios for reactor

the disturbance of descended the reflux flow

the disturbance of insufficient steam heating for column bottom are introduced reasonably in the dynamic simulation system.The dynamic characteristics under the condition of above fault disturbances are simulated and researched deeply

then the virtual fault data is obtained.The problem which the fault information cann’t be gained by experimental research in the actual distillation process equipment is solved in this paper.
