SUBSTANCE FOR CLEANING SOIL AND SOLID SURFACES FROM OIL, INCLUDING FROM OIL AND OIL PRODUCTS, AND METHOD FOR USE THEREOF (VERSIONS) Russian patent published in 2016 - IPC B09C1/00 C09K3/32 C09K17/00 B82B3/00 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to organic chemistry and can be used for cleaning soil from oil, including from oil, masout, hydrocarbons, liquid fuel, as well as for treatment and collection of oil, oil, masout, fuel, hydrocarbons and other oil products from solid surfaces, for example, from inner surfaces of tanks for storage of oil or oil products, equipment used during production, processing, transportation of oil, equipment used for production of oil products, drilling mud, gravel and sand at storage facilities or other solid surfaces. Substance for cleaning soil and solid surfaces from oil is an aqueous solution of natural polysaccharide and surfactant. Natural polysaccharide used is microgels of polysaccharides of molecular weight from 20,000 to 200,000 Da and particle size from 50 to 600 nm. Total concentration of microgels of polysaccharides and surfactant in aqueous solution is not less than 0.2 g/l, and ratio of microgels of polysaccharides to surfactant ranges from 10:1 to 1:10.

EFFECT: group of inventions provides high efficiency of cleaning solid surfaces or soil from oil, reduced specific consumption of reagents with simultaneous increase of environmental safety of cleaning solid surfaces or soil from oil and enabling recycling of oil removed from soil and solid surfaces, as well as surfactants.
