Structural Modeling of Controllable Diffusion in Case of Inter-Component Chemical Reaction

Abstract: Building a closed control system requires a mathematical model that will accurately reflect the dynamics of its associated process. The dynamics of chemical processes largely depends on the reactor design, the nature of reagents, the reactor temperature, and other conditions. Mathematical modeling of chemical processes is often complicated by the uneven distribution of the interacting components throughout the reactor. Modeling such processes requires using the theory of distributed parameter systems. This research is to develop structural models of typical dynamic processes to describe the diffusional displacement model and the ideal displacement model provided an inter-component chemical reaction takes place; the models are based on the structural theory of distributed parameter systems. Linearization of the developed models is considered.

Time-Optimal Control of Chemical Neutralization Process

Abstract: The existing heat and power generation technologies involve the utilization of chemically treated water. Water treatment produces alkaline and acidic wastewaters, which must be neutralized. The paper considers the problem of optimal control of the chemical neutralization of acidic wastewater by means of lime water. The installation for neutralization consists of a tank and a recycling pipeline. The mathematical model of chemical neutralization comprises systems of nonlinear differential equations in parabolic partial derivatives to take into account the chemical reaction between the interacting components placed in the recycling pipeline or in the tank. The controlling action is alkali inflow rate at the inlet of the recycling-pump. The optimization problem is formulated as a problem of time-optimal control. It is shown that the time-optimal process of chemical neutralization is also optimal from the point of view of the accuracy of approaching to the neutral state.
