Destruction of liquid toxic wastes  

The technology is intended to guarantee the destruction of especially toxic liquid waste: polychlorinated biphenyls; halogen-containing hydrocarbons and other substances; freons; chemical warfare agents and their products; other liquid toxic waste.

Liquid wastes are injected into the tunnel reactor where they are ignited and burned at temperature of 1200-1300 °C. Flue gas is then fed into a vortex reactor, where at 1400-1500 °C and at a significant residence time there is a final oxidation and mineralization of the organic matter. Flue gases from the reactor are quenched and fed to multi-stage cooling and cleaning system. The installation can be applied in the area of local formation or accumulations of liquid toxic waste.

Main advantages:

• High temperature with sufficient residence time ensures complete destruction of resistant organic compounds.
• Compactness of the process equipment.
• High environmental friendliness

Scheme of process of destruction of liquidtoxic wastes

1 - liquid toxic waste; 2 - inflammable solvent (if necessary); 3 - water; 4 - dosing pump;
