For the process safety management system of the oxidative pyrolysis process, in which the lower level provides the required flow characteristics of local control loops, and the upper level is the main one from the point of view of ensuring technological safety, cal-culating the tasks for the lower level controllers with regard to safety requirements, the algorithm of the upper level is presented. In accordance with the proposed algorithm, the values of the technological parameters arrive at the input of the regulator, where the determination of the safety area and safety center occurs, as points in the multidimensional space formed by technological limitations, as well as calculating the value of the safety index as the distance from the process operating point to the boundary determined by the respective restrictions. After comparing the actual values of the technological parameters with those calculated by the mathematical model, the control actions for the lower level controllers of the control system are calculated in the direction of removing the boundaries of the safety region. On the basis of the proposed algorithm to prevent the transition of the oxidative pyrolysis process to an emergency or pre-emergency situation, it is possible to create a decision support system that allows, after obtaining the characteristics of the state of the oxidative pyrolysis process, to determine the value of its technological safety center; adjust the parameters determined using a mathematical model of the process; predict intermediate values of periodically measured variables characterizing the safety of the process; calculate the values of tasks for regulators of local process control loops, which makes it possible to prevent the occurrence of emergency and pre-emergency situations, as well as carry out this process in the most efficient way, both from the point of view of obtaining acetylene as a product of the oxidative pyrolysis process of natural gas, and from the point of view of reducing adverse effects on the environment (emissions of harmful and hazardous substances into the aquatic environment and atmosphere) and serving perso al.
