DEAR air separation has been committed to the development and application of control system in air separation plant for many years, especially the Siemens SIMATIC S7-300 / 400H system, with rich practical experience. The instrument and electrical control system of air separation plant can save the data of the whole project, including the symbols and descriptions of CPU, etc., so it is helpful for convenient maintenance. In addition, the diagnosis function of the powerful integrated system can enhance the practicability of the controller and improve its working efficiency. Therefore, the process diagnosis function can be set up to analyze process problems, so as to reduce downtime and further promote production efficiency.
