Background. To determine the concentration of impurities in the gas that is transported through the pipeline, special devices are used, which makes gas transportation for the purchase of these devices more expensive to install and their maintenance costs. The goal is to reduce costs by using a more efficient way to determine the concentration of impurities using a specially developed mathematical model that will allow you to obtain data in an automated calculation process. Materials and methods. The study of hydraulic patterns that contribute to the establishment of optimal and reliable characteristics of the gas supply system. Results. Hydraulic patterns are obtained that determine the averaged changes in the concentrations of impurities in a gas over the working cross section of the flow. The dynamics of changes in pressure in a gas pipe is shown taking into account changes in hydraulic resistance to friction. Balance equations are developed and hydraulic dependencies are described with the aim of finding impurity concentrations over the entire volume of the pipeline. The changes in gas pressure at the start and stop of the pumping stations in the gas supply system are shown. Conclusions. Thus, by determining the concentration of impurities in the gas during its transportation, it is possible to minimize violations of the hydraulic mode of its operation, reducing the loss of all capacities by more than 12 times from the established design indicators.
