COMPOSITION FOR LIQUIDATING OIL SPILL Russian patent published in 2020 - IPC C02F1/28 C02F1/68 C02F101/32 C09K3/32 B01J20/08 B01J20/10 B01J20/16 B01J20/26 B01J20/30 

FIELD: environmental protection.

SUBSTANCE: invention relates to environmental protection and can be used for liquidation of oil accumulations during production, transportation and storage of hydrocarbon raw material and products of its processing. Composition for liquidation of oil accumulations contains the following, wt%: porous hydrophobisated powdered carrier – 0.05–90.0, hydrotrope – 0.05–95.0, surface-active substance, which is represented by non-ionic, zwitterionic surfactants or their mixtures – 0–47.0, powdered gas-producing agent represented by medium or acid salt of carbonic acid or their mixture – 0.2–70.0, powdered acidic agent represented by solid organic acid – balance up to 100.

EFFECT: technical result is to reduce inter-phase tension between water and oil or oil products by releasing hydrotropes: low-molecular amphiphilic substances and surfactants when highly dispersed particles of composition with water, improved adsorption of porous carrier particles and organic amphiphilic components: hydrotropes and surfactants in composition at water-oil or water-oil products interface, intensive gas release at contact of composition with water.
