FIELD: process engineering.
SUBSTANCE: invention relates to petrochemical industry. Proposed method comprises preliminary chemical analysis to determine fraction composition of stock, adding surfactant to water, surfactant solution allowing a complete wettability of water drops with extracted fraction. Obtained mix is mixed with stock to water content of 18% and dispersed to water drop diametre of, preferably, 0.15 µ. Now, water drops with adsorbed fraction are separated from stock.
EFFECT: possibility to separate preset fuel fraction from oil products and other liquid mixes of organic substances.
