FIELD: oil and gas industry.
SUBSTANCE: method of associated petroleum gas processing includes gas compression by compressing and cooling liquid hydrocarbons released during gas compression under the conditions of refluxing and reflux stabilization of compressed gas and liquid product. The gas is mixed with the separation gas and is compressed in two stages along with reduction and separation of liquid products to obtain gas separation and stable liquid products. The compressed gas of the second stage is subjected to low-temperature separation to obtain condensate and gas which is fed to the second stage as a refrigerant and taken out as processed gas. The separation of the reduced liquid product at the second stage is carried out in combination with low-temperature separation condensate. At the first stage natural gasoline is obtained as stable liquid product, and at the second - propane-butane fraction is obtained. If necessary, prior to one stage of compression the gas is purified from hydrogen disulfide and mercaptans and/or dried.
EFFECT: expansion of product variety, yield increase and quality upgrade of liquid products.
