The main factors applied to the obtained mathematical models of chemical technological processes for the optimal design and management of those processes are high speed, pressure, temperature, the main feature of multi-phase chemical technological processes and their complexity. This complexity is more evident in the presence of numerous and complex types of parameters, numerous relationships and interactions between them, and the change of one parameter causes a non-linear change of another parameter. The multiplicity of parameters, the complexity of the system, and the breadth of information in mathematical modeling can be done by selecting the parameters that characterize the main process and not simplifying the system. In this study, it was necessary to obtain experimental data of the process of separation of C5-C6 n-parafms from low-boiling gasoline fractions, to choose an effective adsorbent, to develop a mathematical model, to calculate the model parameters and to prove its adequacy. The mathematical model of the process was developed, the order of solving the model equations was determined, the model parameters were calculated and its adequacy was determined. Mathematical modeling plays the main role in the study of the processes in industry. choosing the methods of solving the system of equations of the mathematical description and its implementation in the form of a program and checking the adequacy. The demand for the use of high-purity output products in organic and inorganic synthesis, fine purification of industrial residues for the purpose of removing harmful substances greatly expands the fields of application of adsorption processes. Currently, adsorption technology is developing in two directions: Synthesis of adsorbents that meet modern requirements for conducting the process; Development of new, different types of adsorption processes. Currently, sorption processes are widely used in many production areas, so they require more recent research. Increasing and expanding the economic efficiency of technological processes, as well as modern requirements for environmentally friendly products, determine the importance of developing mathematical models of these processes and chemical-technological the mathematical modeling method is widely used in process design.
