this paper presents the development and calculation of a flow diagram for a gas processing plant (GPP) using the example of the Astrakhan Gas Processing Plant. A detailed technological calculation of the key units of the plant has been performed, including an absorber for cleaning gas from acidic components (H₂S, CO₂) using a solution of monoethanolamine (MEA), a desorber for regenerating the saturated absorber, and a gas drying unit using diethylene glycol and an adsorbent. For the fractionation unit, a calculation of the rectification column was performed, including the determination of the material and heat balances, operating parameters (pressure, temperature), the number of theoretical plates, and the minimum phlegm number. The main geometric parameters of the apparatuses were determined. The results of the work demonstrate the effectiveness of the proposed process scheme in achieving the specified indicators for the extraction of target components and the deep drying of the processed gas.

Keywords: gas processing plant, material balance, absorber, desorber, gas drying, rectification column
