Electronics Industry: Silicon Tetrachloride Fume Problem Solved Electronics Industry Two-Stage Scrubber System Solves Fume Proble A two-stage Jet-Venturi scrubber/packed tower system solved a number of pollution problems for an Albany, Oregon, company. The Zirconium Extraction Div. of Teledyne Wah Chang produces high-quality reactor-grade zirconium and hafnium ozide using a chemical separation process. The zirconium and the hafnium are chlorinated and then formed into pure metals for the nuclear and chemical process industries. The processing of zirconium produces silicon tetrachloride (SiCI4) as a byproduct. The crude inorganic chemical is stored in a tank farm, processed intopure SiCI4 , and sold as a raw material to other chemical processors. Because the silicon tetrachloride generates
