Research and Engineering Application of Automatic Technology of Nitrate Absorption System
Fengshan Chemical Company of Jizhong Energy Well Mining Group adopts direct process to produce sodium nitrate and sodium nitrite,and the absorption posts of the existing three nitrate production lines are all manually operated on site without setting automatic control measures.In order to reduce the labor intensity and number of on-site personnel,and improve the degree of automation and safety level,Fengshan Chemical Company decided to conduct automated research on nitrate absorption system.According to the company's production process and the actual situation of the site,a new set of automatic control system(DCS system)is added to carry out remote control and safety protection for the three line absorption system,and set up supporting facilities such as regulating valves and various instruments.The data is connected with the DCS system,and the data of gas temperature,liquid temperature,import and export pressure and liquid level of each tower and tank are monitored in real time.And set alarm and interlock,in the industry for the first time to achieve the absorption system automatic control and long-term operation,improve the company's automation level,to ensure safe production.
