Abstract: FIELD: oil and gas industry. 
     SUBSTANCE: proposal relates to oil and gas industry, namely to methods for drying associated petroleum gas. Method for preliminary drying of associated petroleum gas, involving supply of high-pressure associated gas flow in housing with nozzle, its isoenthalpy expansion and cooling during flow in nozzle, condensation of components during cooling, separating condensate from gas phase, increasing gas pressure by braking, wherein initial gas is also cooled during heat exchange with coolant. Component composition of associated gas and boiling point of low-temperature components and / or water in associated gas, which are a coolant, are pre-determined. Boiling point of low-temperature components and/or water is determined at temperature of incoming gas. From the main gas flow, a portion of the gas stream is extracted and directed into the housing through the nozzle, sufficient for providing high-pressure flow through the nozzle, in which the flow rate maintains pressure for the boiling point of the low-temperature components and / or water in the housing inserted into the cooling chamber, in which there is separation of condensate from gas phase of main gas flow to extract condensate into main condensate collector from lower point, and dried gas – into next stage of treatment. Counter gas flows are provided in the housing and cooling chamber, at the outlet of which gas pressure is increased by braking in the volume chamber communicated with the additional condensate collector to discharge the formed condensate from the volume chamber and gas passing through the housing. From the additional condensate collector the condensate is periodically supplied to the main condensate collector, and gas is pumped out with the jet pump installed before the cooling chamber after the flow separation. In the cooling chamber the temperature is maintained below the steam saturation temperature at pumping division, but above the freezing point of water.
