Patent ID: 7214349

Claim:
An apparatus for treating an effluent fluid stream from one or more semiconductor manufacturing process tools, comprising: a pre-treatment unit, downstream from at least one semiconductor manufacturing process tool, arranged to remove water soluble components from the effluent fluid stream; an oxidizing unit, downstream from the pre-treatment unit, arranged to elevate the temperature of the effluent fluid stream, utilize a hydrogen source to effect destruction of at least a portion of halogen-containing components of the effluent fluid stream and effect oxidation of at least a portion of the oxidizable components of the effluent fluid stream; and a quench unit, downstream from the oxidizing unit, arranged to lower the temperature of the effluent fluid stream, wherein water vapor from the quench unit is recycled back to the oxidizing unit for utilization as a hydrogen source to effect destruction of at least portion of the halogen-containing components of the effluent fluid stream; and a post-treatment unit, downstream from the quench unit, arranged to remove acidic components from the effluent fluid stream.
