Nowadays existing technological process management systems increasingly require the development of criteria related to ensuring the quantity, quality and technological safety requirements of chemical technological processes. Due to the specific characteristics of these criteria and their subjectivity, the task of repeatedly checking and evaluating remains relevant. In this article, the parameters important in the production of pyrogas, which is the main product in the production of acetylene, and a method of complete control of the safety of the technological process have been developed. In the specified installation, an optimal automatic control system is installed so that we can control the parameters of the pyrolysis process: flow, temperature and pressure. In the article, the parameter control system in the technological process in the TIA Portal V15.1 software is built on the basis of the PID controller. In addition, system functionality, specifications, hardware and device models were also reviewed. It is aimed at reducing the impact of the human factor and increasing safety in production. Also, the basic principles of hardware management at different levels are presented to ensure high reliability of the entire system.
