METHOD FOR THERMAL DECONTAMINATION OF CHLORINE-CONTAINING ORGANIC SUBSTANCES AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2012 - IPC F23G7/04 F23G7/06 

FIELD: chemistry.

SUBSTANCE: method involves burning a mixture of chlorine-containing organic substances in the first zone of a three-zone reactor at temperature 3500°C and pressure P=10⁶ Pa. The products of combustion and decomposition of chlorine-containing organic substances, steam from cooling water and hardening liquid are then mixed in an agitator while lowering temperature of the mixture to 1200°C. Said mixture is held in the second zone of the reactor for 1 ms. After the second hardening step at the boundary of the second and third zones, the mixture is held in the third zone until complete evaporation of the hardening liquid and then output therefrom through a critical nozzle into a condenser. The water condensate of said vapour-gas mixture is neutralised with soda to obtain sodium chloride as a commercial product. The device for realising said method is described.

EFFECT: high efficiency of thermal decontamination of chlorine-containing organic substances.
