There was developed a computer model for simulation of thermal regimes in electro thermal reactor, allowing to visualize the main characteristics of the process. This model takes into account the correlation of thermal processes in the areas of differing phase composition, and gives the opportunity to get an idea about the reaction of the object on various kinds of disturbances, such as changes in charge composition, and dosage, reducing the voltage across the electrodes. A mathematical model of reactor in lumped parameter approximation is a specific system of nonlinear ordinary differential equations, supplemented by the terms of the phase transition zones of different phase states. Peculiarity of this model is consideration of energy feedstock in the area, giving the opportunity to track the temperature level under the crest of the furnace, which is very important to maintain the regime in closed furnaces, having a set, withstanding low temperatures. The ratios (taking into account the phase transition) were used for consideration of processes in the bulk reactor with different phase composition as a whole, which made it possible to modify the flow reactor model with respect to the specifics of this kind of recovery. Numerical methods were used for the model implementation. The model allows to calculate the evolution of the temperature in different reactor zones, and to track the changes over time as a band structure with different phase composition. The simulator program, implementing the concept of virtual reality, can be efficiently used for adaptation of the staff in management unit, along with fixation of process parameters for the processes visualization in reaction zone inaccessible instrumentation control. The offered model allows to build the maps for stationary conditions, showing the dependence of the main process parameters (coke zone height, reaction zone temperature, concentration of reactants and required product at the reactor outlet, etc.), as well as technical and economic indicators of basic parameters (voltage across the electrodes, coke content in the mixture with known mixture compositions).
This work was carried out within the basic part of the State task of Ministry of Education and Science of Russian Federation No. 2014/123 for carrying out of the State works in the sphere of scientific activity, project No. 2493.
