Software implementation of the dynamic model of the first stage of the reactor unit for styrene production in the MATLAB/SIMULINK environment

Abstract

A mathematical description of the physicochemical processes occurring in the first stage of ethylbenzene dehydrogenation in a two-stage adiabatic continuous reactor is developed. A software implementation of the resulting model in Matlab/Simulink environment is presented, that allows to simulate the sequence and dynamics of the flow of internal processes during the equipment operation, taking into account the decrease in activity of the catalytic layer. The algorithm of functioning, structure and model of information flows of the created software, implementing a modular approach to the description of a series-parallel system of thermal, chemical processes and processes on the surface of the catalytic layer are given. The created software allows to simulate the operation of the reactor stage when process parameters change.
