Method and apparatus for producing a product in a regenerator furnace from impure waste containing a non-gasifiable impurity
First Claim
1. A method for producing a product in a regenerator furnace subsystem from a waste containing a non-gasifiable impurity for the regenerator furnace subsystem, comprising the steps of:
- a) introducing the waste, said waste including at least one sulfur compound suitable as a feed for a regenerator furnace, into a molten metal bath maintained under conditions sufficient to dissociate said waste and form a gasified feed component for the regenerator furnace subsystem, whereby said waste dissociates and forms the gasified feed component and a non-gasifiable impurity;
b) directing said gasified feed component through a means for removing an impurity from said gasified feed component; and
c) directing the gasified feed component into the regenerator furnace subsystem maintained under conditions sufficient to convert the gasified feed component into said product.

Abstract
An apparatus and method for producing a product, such as hydrogen halide gas or sulfuric acid, in a regenerator furnace subsystem from a waste containing a non-gasifiable impurity. The method of the invention includes directing a waste, containing a non-gasifiable impurity into a reaction zone, containing a molten metal bath, in a reactor maintained under conditions sufficient to dissociate the waste and to form a gasified feed component and a non-gasifiable impurity. The gasified feed component is then directed from the reactor to a regenerator furnace subsystem, maintained under conditions sufficient to convert the gasified feed component to the desired product.
The apparatus of the invention includes a reactor having a waste inlet and a gaseous effluent, a reaction zone containing a molten-metal bath for dissociating the waste, containing a non-gasifiable impurity, and forming a gasified feed component, and a lance for injecting the waste into the reaction zone. The apparatus also includes a regenerator furnace subsystem, for converting the gasified feed component to the desired product, and a means for directing the gasified feed component from the reactor into the regenerator furnace subsystem.

16. A method for producing a product in a regenerator furnace subsystem from a waste containing a non-gasifiable impurity for the regenerator furnace subsystem, comprising the steps of:
-
a) introducing the waste, said waste including at least one sulfur compound suitable as a feed for a regenerator furnace, into a molten metal bath that includes a vitreous layer, which is disposed at an upper portion of the molten metal bath, the molten metal bath being maintained under conditions sufficient to dissociate said waste and form a gasified feed component for the regenerator furnace subsystem, whereby said waste dissociates and forms the gasified feed component and a non-gasifiable impurity, and whereby the vitreous layer removes an impurity from the gasified feed component; and b) directing the gasified feed component into the regenerator furnace subsystem maintained under conditions sufficient to convert the gasified fed component into said product. - View Dependent Claims (17)
