FIELD: oil and gas industry.
SUBSTANCE: method for non-waste pretreatment of production fluid involves stepwise separation of wet gas to produce condensate and gas at each stage, separating the first stage gas under reflux conditions and reducing the second stage gas. The gas of the first stage and debutanization gas are dried. The dried first stage gas is reduced and separated in the second stage by cooling with the reduced second stage gas, which is then mixed with the dried debutanization gas and withdrawn as a sales one. The condensates of the first and second stages are reduced and debutanized to produce gas and sales condensate.
EFFECT: elimination of hydrate formation inhibitor consumption, elimination of light gas components losses and improvement of condensate quality.
