Abstract
An organic waste containing halogen is destroyed by treatment in a molten salt pool comprising a mixture of a basic alkaline earth metal compound with an alkaline earth metal halide. An oxygen-containing gas is introduced into the pool containing the waste to produce a gaseous combustion product and to cause the halogen present in the waste to react with the basic alkaline earth metal compound to produce additional alkaline earth metal halide.
Claims13
A process for destroying a halogen-containing organic waste which comprises:
- providing a molten salt pool containing a basic alkaline earth metal compound selected from the group consisting of alkaline earth metal oxides and carbonates and an alkaline earth metal halide;
- introducing into said molten salt pool a halogen-containing organic waste and an oxygen-containing gas in an amount sufficient to convert said waste into a gaseous combustion product and to cause the halogen present in said waste to react with said basic alkaline earth metal compound to form additional alkaline earth metal halide.
A process for treating an organic waste containing halogen and nonreactive metal values which comprises:
- providing a molten salt pool comprising a mixture of a basic alkaline earth metal compound selected from the group consisting of alkaline earth metal oxides and carbonates with an alkaline earth metal halide;
- introducing into said pool a halogen-containing organic waste and an oxygen-containing gas in an amount sufficient to convert said waste into a gaseous combustion product and to cause the halogen present in said waste to react with said basic alkaline earth metal compound to form additional alkaline earth metal halide;
- recovering said gaseous product, said alkaline earth metal halide and said nonreactive metal values from said molten salt pool;
- and
- adding to said molten salt pool as salt makeup an alkaline earth metal oxide or carbonate.
