FIELD: oil and gas industry.
SUBSTANCE: three-product gas treatment plant includes the inlet separator, the reflux exchanger, the reduction device and the low-temperature separator. There is the ejector equipped with the debutanization gas feeding line before the input separator. The recuperation heat exchanger and the reduction device are installed before the reflux exchanger. The low-temperature separator is connected by the deethanization gas and the condensate feeding lines to the deethanizer, equipped with the propane-butane fraction outlet line, connected to the condensate feeding line reflux exchanger, at which the reduction device is installed. The plant includes the reduction device and the debutanizer, equipped with the debutanization gas lines and the stable condensate outlet. The heat exchanger for cooling at least the part of the debutanization gas is placed at the condensate feeding line from the reflux exchanger between the reduction device and the deethanizer.
EFFECT: expansion of the products range and the quality of the traded gas and condensate improvement.
