Резюме:

the report is devoted to the development of a flow chart and calculation of the commodity balance of a gas processing plant (GPP) based on a given composition, volume and parameters of incoming hydrocarbon gas (V = 10,000 m3/h, with a content of Ch₄ 78%, c₂h₆ 6.5%, C₃h₈ 4.2%, etc.), as well as extraction coefficients and the content of basic components in technical fractions. A technological scheme of processing is proposed, including purification from acidic components (HS, CO₂) in an absorber using monoethanolamine (MEA), desorption, drying of gas with diethylene glycol and adsorbent (zeolite), rectification for separation into fractions (ethane, propane, iso- and n-butane, C₅+). The material and thermal balances of key apparatuses, calculations of column diameters, the number of theoretical plates and the minimum phlegm number were performed. A block diagram of a gas processing plant with purification, compression, bleaching and gas fractionation units is presented.

Keywords: commodity balance., extraction coefficient, distillation column, gas drying, desorber, absorber, heat balance, material balance, flow diagram, gas processing plant
