Abstract RU 2086614 C1

FIELD: chemical industry. SUBSTANCE: method of recuperation of oil from dispersive water-oil medium comprises treating said material with sorbent granules and subsequently separating oil saturated sorbent granules from water. The sorbent is hydrophobic and oleophilic silicagel which has specific surface area of 600-650 sq.m/g, bulk density of not higher than 0.07 g/cu. cm and oil capacity of at least 12 g of oil/1 g of sorbent. Sorbed oil is separated by desorption with hydrocarbon solvent which evaporates at temperature lower than initial oil boiling temperature to obtain regenerated sorbent and oil solution in hydrocarbon solvent, and oil is separated from solvent. EFFECT: more efficient recuperation method. 2 tbl
