Abstract

This paper consider a modeling method for the chemical plant which produces soda and chloride by electrolysis of salt water. A mathematical model for a chloride gas generation plant is built on ARX (Auto-Regressive Exogenous) model where the input and output are opening rate of the control valves and the pressure of chlorine gas in the reaction tank, respectively. Using real measurement data for the chemical plant, the ARX model is constructed where the best order of the model is determined by AIC criterion. Finally, the simulation results are illustrated to show qualitatively the effectiveness of the mathematical model used here for the pressure of chlorine gas.
