Design of Continuous Process Control System Based on PCS7 and SMPT-1000
Taking the mixing tank,reactor,flash tank and condensing tank of SMPT-1000 experimental platform as the controlled objects,the continuous process system is simulated.Analyzing the characteristics of the reaction process and considering the requirements of system process parameters,safety and stability,the control loop and driving sequence are designed in this paper.A feasible control scheme is designed using Siemens PCS7 system.Simulation experiments are carried out based on SMPT-1000 experimental platform,and the experimental operation results show that,under the premise of ensuring safety and stability,the system's parameters such as liquid level,pressure,temperature and flow rate can meet the requirements of process parameters and realize automatic control,and the purity of the system product reaches more than 75%,which meets the actual production requirements.
