METHOD OF INTEGRATED WASTE MANAGEMENT FOR OILY WASTES WITH RANDOM COMPOSITION AND PLANT FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC C10G1/00 C10G69/04 B09B3/00 

FIELD: oil and gas industry.

SUBSTANCE: method of integrated waste management for oily wastes with random composition with production wide range of energy sources include low-temperature pyrolysis with heating source, before pyrolysis oily wastes with random composition are sorted during accumulation, mixed mechanically in the preset ratio and homogenised thermally with moisture evaporation by flue gases at temperature of 100-130°C, in process pyrolysis gas is sent to condensation unit in order to separate light hydrocarbon fractions from heavy ones. Light fractions are directed to rectification tower with production of benzene, kerosene and diesel fuel, heave fractions with residual oil from condensation unit are delivered to pre-activation unit where oxidation cracking takes place within temperature range of 250-350°C with air purging with ratio of 1:(300-500); after oxidation cracking activated heave fractions are delivered to catalytic cracking for additional production of benzene, kerosene and diesel fuel and fuel oil, bitumen and tar oil; after pyrolysis solid pyrolysate is transferred and water-gas generator, flue combustion gases from condensation column are delivered to water-gas generator, at that flue combustion gases are enriched by superheated steam and in solid pyrolysate they are converted to gaseous energy carrier - water gas. Additionally one proposes a plant for the method implementation.

EFFECT: increasing energy efficiency of integrated waste management for oily wastes with random composition with additional receipt of wide range of energy carriers and construction materials.
