Abstract:
A method for treating an effluent fluid stream comprising one or more halogen-containing components from one or more semiconductor manufacturing process tools, using a system that includes an oxidizing unit having one or more inlet units at one end and a gas flow path susceptible to corrosion in exposure to said effluent fluid stream, comprising the steps of:introducing said effluent fluid stream to the oxidizing unit through the inlet end; providing water vapor to the inlet end for mixing with the effluent fluid stream in said oxidizing unit; effecting, at the inlet end of the oxidizing unit, the conversion of at least a portion of the halogen-containing components of the effluent fluid stream to a form that is more treatable using said water vapor; and effecting, in the oxidizing unit, the oxidation of at least a portion of the oxidizable components of the effluent fluid stream, wherein the water vapor flows between the introduced halogen-containing effluent fluid stream and interior wall of the gas flow path of said oxidizing unit to thereby project said gas flow path from corrosion.
