Annotation | The paper considers modern approaches to the organization of interdisciplinary and interregional work in the mathematical modeling of complex industrial processes of chemical technology. Today, when industrial chemical technology plants operate in a highly competitive mode, mathematical modeling methods become the most effective and low-cost way to optimize physico-chemical processes in order to improve the quality of products and increase profits. The experience of cooperation with colleagues from the Laboratory of Dynamic and Controlled Systems of the Department of Differential Equations, Mathematical and Numerical Analysis, the Institute of Information Technology, Mathematics and Mechanics of Nizhny Novgorod State University named after N.I. Lobachevsky is given. Using the example of mathematical modeling of the industrially important process of sulfuric acid alkylation of isobutane with olefins, an effective organization of joint work with a clear allocation of scientific specialization of scientific schools of Ufa and Nizhny Novgorod is shown. The result of such interregional and interdisciplinary work was the development of a kinetic model of the reaction of sulfuric acid alkylation of isobutane with olefins using an asynchronous global optimization algorithm. Also, the result of the presented work is the formulation of new problems of mathematical modeling and optimization of the above process. The purpose of which is to determine the optimal ratio of the initial reagents (isobutane/olefin), the concentration of the catalyst (sulfuric acid) and the temperature of the industrial alkylation process for maximum product yield. |

Keywords | interregional and interdisciplinary approach, hierarchical structure of mathematical modeling of chemical-technological processes, kinetic modeling, alkylation of isobutane with olefins, asynchronous algorithm of global optimization, the problems of optimal control of chemical processes. |
