In accordance with the law of preservation of the amount of substance, an imitation model for the process of two-stage oil separation has been developed. The creation of this model took into account the features of the operating mode of the horizontally placed separators B-1 and B-2 of the first and second stages of separation. The simulation mathematical model after the identification of parameters was investigated by a numerical method that takes into account the effect of perturbations on the separation process, which is a consequence of the action of a number of physical quantities from the environment on the object. Automated control systems that operate on the principle of negative feedback were used to stabilize the main technological parameters of oil separation. But since the deviation of the regulated quantities from their given values is small, this allowed linearizing the nonlinear model of the two-stage separation process. After studying the simulation model by a numerical method, it is established that the mathematical model of the installation of two-stage separation can be used for the synthesis of effective control systems of the two-stage separation process and the creation of mathematical models in terms of “input-output”. The obtained numerical and graphical result in the form of functional dependencies allows us to establish the relationship of technological parameters, in other words, the change of the value of the parameters at the second stage of separation will depend on the first one and vice versa. Thus, the applied aspect of using the obtained scientific result is the possibility of improving the typical technological process of oil separation.
