FIELD: oil industry.
SUBSTANCE: invention is intended for processing of petrochemical industrial wastes. Wastes from production of polyethers are treated with extraction agent. Mixture is separated by pressing and centrifuging to obtain liquid solution of laprol and extraction agent, and solid fraction of bentonite. Extraction agent is separated from liquid fraction with its subsequent recovery to process. Solid fraction is washed with organic solvents, or with water and condensate. Solid fraction is filtered and annealed in vacuum medium at temperature t = 400 °C to obtain activated carbon. Drilling fluid with potassium and phosphorus salts is evaporated to solid potassium monophosphate. Laprol is passed through disperser for producing foam-rubber of increased volume and density.
EFFECT: invention provides non-waste production of polyethers.
