Statement of the problem. Reliable operation of modern high-precision gas flow reduction and control systems located in cabinet, block and capital gas distribution points calls for the use of two-stage cylindrical gas purification plants containing preliminary and fine filters. An urgent task is to design and scientifically substantiate the use of cost-effective two-stage natural gas purification devices located at gas distribution points as well as the development of analytical calculation methods for identifying pressure losses in the filter elements of two-stage cylindrical installations and the timing of their regeneration.Results. Theoretical and experimental identification of pressure losses depending on the degree of clogging of a multilayer filter element with mechanical impurities is given.Conclusions. Analytical equations for identifying pressure losses are obtained which differ from the known solutions in that the effect of clogging with mechanical impurities in a multilayer filter cloth is first presented as the sum of pressure losses on a number of clean calibrated grids located one after another, with the cell sizes of each subsequent grid less than the previous one.
