Method for treatment of fluid hazardous, organic waste materials, where a plasma of 2000-5000° C. temperature is generated by means of an electric arc in a plasma generator, the plasma torch is directed into a reactor, the reactor consists of three zones ( 4 A, 4 B, 4 C), the plasma torch being introduced downwards into the uppermost first zone ( 4 A), the fluid waste ( 1 ) being sprayed into the plasma torch in the first zone ( 4 A), where it is heated to a temperature range of 1300-1600° C., the mixture of the plasma and the waste is introduced into the second zone ( 4 B) of the reactor, where an oxidizing material is added ( 5 ) to the mixture, the combustion gas produced in the second zone ( 4 B) is then led into the third zone ( 4 C) of the reactor, where it is cooled rapidly by water spraying to a temperature range of 120-160° C., the cooled combustion gas is removed from the third zone ( 4 C) of the reactor is led into a cooler. The plasma torch is generated from the mixture of carbon dioxide and oxygen, the oxidizing material introduced into the second zone ( 4 B) of the reactor is a mixture of carbon dioxide and oxygen. Subsequently the water content of the combustion gas is separated by condensing and is removed and the residual combustion gas is removed. |
