Информационно-управляющая система процесса пиролиза пропанона

Abstract

The paper presents a solution to the problem of developing an information and control system for the process of propanone pyrolysis, which is the main source for the production of acetylketene, which is widely used in the synthesis of medicines and food additives, insecticides and fungicides, and paints and varnishes. A mathematical model of the propanone pyrolysis process in tube furnace coils has been developed, which takes into account the heat transfer in the reaction zone of the pyro coil by means of radiation from the walls of red-hot mines. The problem of identifying the kinetic parameters of the pyrolysis model on the basis of experimental data obtained at the facility was posed and solved. The problem of static optimization of the propanone pyrolysis process, which consists in maximizing the selectivity of the process, was posed and solved. The software package is made in C#, which is supported by many SCADA systems. The Hook-Jeeves configuration method was used as an optimizer in combination with the penalty function method. The technical, informational and software support for the information and control system of the process has been developed. To develop an information management system, SCADA software was used - RSView32 systems. It allows you to implement the visualization, accumulation and archiving of technological parameters. The main form of information presentation is the mnemonic diagram of the pyrolysis process, the other forms are called from the mnemonic diagram by pressing the corresponding virtual buttons.
