Improvement and modernization of the technological process of polyvinyl chloride production requires the appropriate development of computer modelling systems, which ensure the following: identification and maintenance of optimal modes of technological processes that contribute to continuous operation, as well as the use of intelligent systems of modelling and control of technological devices. The article proposes pressure-dependent control of the temperature in the reactor, which affects the quality indicators of the technological process, using the cascade control method during the production of polyvinyl chloride. In this work an imitation model of the technological process was developed.

“…In the presented work, modelling software are described that allow to determine such parameters of technological processes that are not capable to direct measurement, but the knowledge of which is necessary for carrying out chemical processes in optimal conditions for a given quality of the products obtained. The article describes a simulation-modelling software of the polymerization process of vinyl chloride, which allows to determine the molecular weight distribution of polymer molecules [1,2], describes the software for modelling the parameters of the electrolyzer in the production of caustic soda, chlorine and hydrogen, which is based on the temperature dependence of the current-voltage characteristic [3,4].…”

This article describes the modelling software complexes are described that allow to determine such parameters of technological processes that can not be directly measured, but knowledge of which is necessary for conducting chemical processes in optimal modes for a given quality of the product. The imitation modelling software of the polymerization of vinyl chloride, which allows determining the molecular mass distribution of polymer molecules, describes a program for modelling the electrolyzer parameters in the production of sodium hydroxide, chlorine and hydrogen, based on the temperature dependence of the current-voltage characteristic. The imitating modelling software of the polymerization process of vinyl chloride allows to determine the physical-chemical properties of polyvinyl chloride in the polymerization process, will help to ensure optimal modes of technological processes, to predict the change in parameters in the event of abnormal situations, which will increase the level of trouble-free functioning.In the training and monitoring modes of operation with the help of imitation software, it is possible to quickly assess the level of training of personnel, and also, if necessary, to conduct their training on the basis of the modules of virtual reproduction of the technological process included in it.Using the developed simulation-modelling software of the process of electrolysis of sodium hydroxide, chlorine and hydrogen production, it is possible to model the temperature dependence of the current-voltage characteristic, which helps to ensure optimal modes of technological processes, to predict the change in parameters in the event of abnormal situations, which will increase the level of troublefree operation.
