Abstract
This paper is a chemical factory 0-chloro-benzoic acid in the automation production system design. This factory 0-chloro-benzoic acid for the traditional mode of production in neighboring pchlorotoluene, glacial acetic acid solution, catalysts and stress conditions in step with air or oxygen and oxidation. In polymerization process, workers need to monitor temperature and pressure gauge, when the design value, manual closing valves, when designing and value than to open the valve. A complete system involves many valves, high risk of artificial demand, so urgent need for its automation reconstruction.
In details about the scene, this paper 0-chloro-benzoic acid reaction kettle of control system design were analyzed carefully. Text is divided into five chapters, the first chapter of the subject research background and significance, and China's chemical automation status. The second chapter to the whole system through an introduction to the analysis and solution of the control method. The third chapter introduces emphatically the selection of hardware circuit design and process, the design. The fourth chapter tells of the software system is designed. The final chapter is to record the process and results of testing system.
Based on PLC control, configuration software monitoring of modern automation control system in chemical industry has the security, stability and economic aspects, efficiency, are currently domestic enterprise needs. Therefore the future of this chemical will have more space.
