Abstract: In the first section of the work, an analysis of natural gas dehydration methods was carried out. Selected absorption method. In the second chapter, technological lines of natural gas dehydration, their features, advantages and disadvantages are considered. The use of various types of absorbents for natural gas dehydration is considered. In the third section, a number of installations for drying gas using the diethylene glycol method for an oil refinery are considered. The selected technological scheme for calculation, modeling and modernization. The fourth chapter provides a description of the selected technological scheme and simulation of such a scheme in the universal modeling program ChemCad. Modeled column of the nozzle type. Calculated packing column with six types of packing. The selected type of nozzle, which provides the possibility of maximum drying of the gas. The operation of the packing column has been optimized, in particular, the optimized diameter of the column, for which the maximum extraction of moisture from the gas has been obtained. By modeling in the universal modeling program ChemCad, the technical characteristics and structural dimensions of the packing column for drying natural gas with diethylene glycol were obtained. for the drying of natural gas with a productivity of 10 million m3/day, it is recommended to use a packing column ("Gempak" (Gempak) 1.5 A) a column with a diameter of 3.2 m and a height of 11 m. Hydraulic resistance in the column is 15 kPa. The average irrigation density is 2.8 m3/m2·h. The economic part has been developed, the cost of the conducted research has been determined.
