An Experimental Model of Continuous Stired Tank Reactor with Acetic Anhydride Hydrolysis for Control Research

One of the methods that generate acetic acid is Anhydride Acetic hydrolysis reactor in Continuous Stirred Tank Reactor (CSTR). For this reason, the article aims at modeling CSTR bioreactor with a view to studying the kinetics and control of the reactor. The paper deals with designing an experimental model based on dynamics and technological parameters of Acetic Anhydride reaction. The model is verified by numerical simulations via starting and operating phases, rating characteristics of the device. The controlling CSTR model is multivariable, nonlinear and coupled. The output feedback controller with PID action is greatly affected by input noise; therefore, there is a need to design noise offset or use nonlinear control.
