Optimized PVC polymerization kettle temperature system design scheme

This paper introduces optimized polymerization kettle of PVC production temperature control scheme. Because polymerization kettle has many features, such as large-scale, many variables and special complex temperature control, we use programmable controller CPU222, apply program control of the polymerization kettle temperature and use double model predictive function control strategy in the algorithm design. The scheme can shorten the time of elimination interference, ensure deviations of control reaction temperature within ±5°C. So it can increase production and stabilize the product quality.
