Abstract:

An algorithm for calculating the optimal temperature profile of a chemical process is developed. The formulation of the problem of optimal control of the chemical process is given. The temperature of the reaction mixture is considered as a control, the values of which are subject to constraints. A finite-dimensional approximating problem is formulated, for the solution of which an algorithm based on the method of differential evolution is constructed. The work of the algorithm is tested on an industrially significant process of phthalic anhydride production. The optimal temperature regimes at which the highest degree of transformation of the starting substance, the highest concentration of the target product and the lowest content of the reaction by-product are achieved are calculated.
