| Abstract: | The application of control system MACSV of HollySys Co. in the production of ion-exchange membrane caustic soda was introduced. The process flow and the hardware configuration were introduced. The main automatic control processes for each procedure were analyzed. The complex automatic control systems for the pH value of desulfated brine, for the pressure of electrolyzer outlet gas-phase manifold, for electrolyte concentration, for the pressure of hydrogen compressor outlet, and for the flow ratio of chlorine to hydrogen feeding to synthesis furnace, were optimized. each technical index met design requirements, and automatic control caustic soda systemn was realized. After commissionng and regulation, of the whole ion-exchange membrane |
