METHOD OF DECONTAMINATING HYDROCARBON-CONTAINING WASTES WITH SIMULTANEOUS DEPOSITION OF DISSOLVED METAL SALTS AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2013 - IPC F23G7/05 C02F11/06 C02F11/18 C02F101/32 C02F1/72 B01D53/44 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of decontaminating hydrocarbon-containing wastes, involving oxidising and compressing the wastes to pressure P>PcrH₂O and then feeding into a reactor. The method is realised by oxidation in the medium of supercritical water at temperature T>TcrH₂O in the presence of an oxidant and is characterised by that the wastes are heated to temperature T>TcrH₂O by a recirculating supercritical solution of the decontaminated wastes directly in the reactor (where PcrH₂O is the critical pressure of water - 218 atm, TcrH₂O is the critical temperature of water - 374°C). The invention also relates to an apparatus realising said method.

EFFECT: preventing precipitation of salts outside the reactor in order to prevent clogging of coiled pipes and simplification of the method.
