FIELD: oil and gas industry.
SUBSTANCE: crude gas is separated at the first stage, obtaining the hydrocarbon, moisture condensate and gas, which is dewatered with obtaining the dry gas of high pressure, reduced and separated at the second stage upon the conditions of partial condensation at the expense of cooling down with gas of the third stage with obtaining the condensed fluid and gas, which is reduced and separated at the third stage jointly with the dry gas of low pressure and the deethanizated gas with obtaining the gas, which after heating will be extracted as the sales, and the condensed fluid, which is deethanizated with obtaining the propane-butane fraction and the deethanizated gas. The condensed fluid of the first and the second stages is reduced and deethanizated with obtaining the sales condensate and the gas, which is dried with obtaining the dry gas of low pressure. The latest is additionally cooled down, if necessary.
EFFECT: exclusion of inhibitory substance consumption of hydrate formation, product differentiation, reducing of hydrocarbon losses.
