FIELD: gas industry.SUBSTANCE: invention relates to method of preparing hydrocarbon gas by low-temperature condensation and can be used in gas industry. Method for preparation of associated oil gas involves separation and successive cooling gas prepared gas and third-party coolant with condensation of reflux, countercurrent contact between gas and condensate after each cooling stage. Gas is premixed with weathering gas, compressed to transportation or processing to produce cooled liquid hydrocarbons and mixed with stabilization gas. Cooling of obtained mixture is carried out in conditions of its partial condensation, besides, condensate is stabilized with receipt of stabilization gas, reduced and separated with production of weathering gas and stabilized.EFFECT: invention increases output of treated gas, improving quality of condensate and preparation of associated petroleum gas of low pressure.1 cl, 1 dwg |
