METHOD OF RECYCLING OIL-OILY-CONTAMINATED WASTES, OILY SCALE, COKE-CHEMICAL WASTES Russian patent published in 2020 - IPC F23G7/05 F23G5/27 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of recycling oil-contaminated wastes, oily scale and coke-chemical wastes. Method comprises drying, capsulation of oil, hydrocarbon, organic parts of wastes or mixture thereof, conversion of wastes into powdery loose form by mixing with active mineral component, inert mineral component or mixture thereof, blowing obtained powdered loose product into tuyere of metallurgical furnaces to produce cast iron by separate flow or together with pulverized coal, gaseous or liquid fuel or burning in furnaces equipped with burners for pulverized fuel, separate flow or together with pulverized coal, gaseous or liquid fuel. Active mineral component is lime, cement, gypsum, cement clinker or mixture thereof.

EFFECT: technical result consists in recycling of large-tonnage industrial wastes, use of energy potential of organic part of man-made wastes, reduction of environmental load.
