Apparatus for treating a gas formed from a waste in a molten metal bath
First Claim
1. An apparatus for treating a gaseous discharge stream formed from a waste in a molten metal bath, comprising:
- a) a reactor having a molten metal bath formed therein and a gaseous discharge port above the molten metal bath;
b) a reaction section extending from the gaseous discharge port;
c) a cooling column extending from the reaction section;
d) separation means in fluid communication with the cooling section for separating a particulate dissociation product from a gaseous component of a gaseous discharge stream formed from a waste in the reactor and passing from the reactor through the reaction section and the cooling column into said separation means;
e) a gaseous discharge conduit extending from the separation means;
f) a cooling section extending from the separation means for cooling a particulate stream formed of the particulate dissociation product separated from the gaseous discharge stream in said separation means;
g) a recirculation conduit extending from the cooling section to the reaction section for conducting at least portion of the particulate stream from the cooling section to the reaction section; and
h) a recycle conduit extending from the cooling section to the reactor for recycling a portion of the particulate stream from the cooling section to the reactor for submerged injection into the molten metal bath.

Abstract
A method and a system is disclosed for treating a gaseous discharge stream formed from a waste in a molten metal bath. The waste is directed into a reactor containing a molten metal bath. The molten metal bath has operating conditions which are sufficient to dissociate the waste and form a gaseous discharge stream including a dissociation product. The gaseous discharge stream is cooled in a cooling section and the dissociation product is separated, as a particulate, from a gaseous component of the gaseous discharge stream. The fluid particulate stream is recirculated to the gaseous discharge stream in a reaction section of the apparatus.
