Weitere Informationen
The scale of coal-to-ethylene glycol plant is large, the logistics and energy flow in the production process are becoming more and more complex, the correlation coupling between variables is increasing, and the fierce market competition makes enterprises put forward higher requirements for product quality, production cost, safety and environmental protection. The process flow and control status of the coal-to-ethylene glycol acid removal device, the technical route, system architecture and control strategy of the advanced process control system are introduced, and the process indicators before and after the operation of advanced process control system are compared. Hubei Sanning Chemical Co., Ltd. solves the coordinated control of many variables between various units of the coal-to-ethylene glycol acid removal device through the advanced process control system, greatly reducing the fluctuation of key controlled variables, achieving automatic control of the entire production operation process, reducing energy consumption for per unit of product, ensuring product quality and reducing the frequency of operator operations [ABSTRACT FROM AUTHOR]
