Aiming at the problems of low automatic control loop utilization rate,low stable rate of unit,multiple alarms and frequent intervention of post personnel in tetrafluoroethylene monomer production unit.By optimizing the control mode of control loop,setting PID parameters and adjusting filtering time,the automatic control loop utilization rate and stability rate of the unit are greatly improved,and the number of personnel intervention and mean alarm is reduced.On this basis,the alarm optimization work is carried out,the alarm principle is established,and the priority of process alarm is optimized.Through the above two optimization work,the automatic control loop operation rate of the unit is increased from 73.3％to 97.4％,the unit stability rate is increased from 83.1％to 98.1％,the frequency of personnel intervention is decreased by 84.6％,the average alarm is reduced from 12 to 2 per hour,and the alarm state of the unit reaches L4(robust)level.
