Abstract
The article presents the results of the study on solving the problems of developing mathematical models of the atmospheric column, which is the main unit of the primary processing plant of the Atyrau oil refinery. The structures of the mathematical models of the studied main unit of the primary oil refining plant, which produces the main products of the primary oil refining plant, are identified based on the methods of mathematical planning of experiments and the idea of sequential inclusion of regressors. The structure of the models is indexed in the form of nonlinear regression equations. In the work, the corresponding tools of the MATLAB system are used to identify the parameters of the obtained model structures.
