FIELD: oil and gas.
SUBSTANCE: invention refers to method of hydrocarbons C3+ separation from associated oil gases by means of counterflow absorption with absorbent with the following desorption of absorbed fraction C3+, and recovered absorbent returned into absorber after desorption. This method is characterised by means of using the associated oil gases with the pressure of 8-20 atmospheres and carrying out absorption at the temperature of 8-40°C. In this case rich absorbent leaving the absorber is heated up to 280-350°C and supplied to desorption which is carried out at the pressure of 15-19 atmospheres, and heavy components of initial associated gases are used as absorber.
EFFECT: enabling process simplification.
