Title:
PHASE TRANSFER CATALYSIS SCRUBBER
Document Type and Number:
WIPO Patent Application WO2004105929
Kind Code:
A3
Abstract:
A method and system for reactively destroying alkyl halides in volume or stream of gas. The method and device employ nucleophilic reaction of the alkyl halide under phase transfer catalysis conditions. The method and system are useful for scrubbing applications requiring the reduction of alkyl halide concentrations to very low levels.
