FIELD: chemistry.
SUBSTANCE: invention relates to techniques for removing oil and oil product spills and can be used in the oil extraction and oil refining industry, as well as in transportation. A sorbent is fed to the site of the oil or oil product spill in the water using a flexible or rigid line. The sorbent used is an aqueous solution of microgels of polysaccharides with molecular weight of 20000-200000 Da. Concentration of microgels of polysaccharides at the spill site is kept at least equal to 0.1 g/l. The jelly-like agglomerates formed are then mechanically collected.
EFFECT: high efficiency of localising and collecting underwater and subglacial oil spills while simultaneously increasing the amount of recovered oil, easier assembling of the equipment.
