AI Technical Summary
The calculation of the prepolymerization conversion rate of vinyl chloride has a deviation, mainly due to the large temperature difference in the reactor body and the scale buildup in the jacket caused by water quality affecting the heat exchange value.
An online monitoring device for the conversion rate of vinyl chloride prepolymerization was designed, including a monitoring tank, a weighing module, a jacket, a circulating water assembly, a gas holder, and a vinyl chloride prepolymerization seed discharge pipe. The conversion rate is calculated by controlling the temperature and weighing. The temperature of the monitoring tank is controlled by the hot and cold water circulation of the circulating water assembly, and the conversion rate is calculated in combination with the weighing module.
It improves the accuracy of vinyl chloride prepolymerization conversion rate and reduces calculation deviations caused by temperature differences and jacket scaling.
