In salt chemical production processes, the automation control system is required to be very reliable, safe, and advanced. The system’s control capabilities and control functions are of utmost importance. HollySys has developed thousands of applications for soda, polyvinyl chloride, inorganic salt, triacid, chemical fertilisers, inorganic new materials, and chlor-alkali, and has provided DCS automation products in typical facilities such as caustic soda, polyethylene, polyvinyl chloride, caustic soda evaporation, soda, and ammonia alkali.
