Method of treating gaseous waste from an optical fiber preform fabrication unit

摘要

A method of treating gaseous waste from an optical fiber preform fabrication unit containing halogenated compounds includes a step of forming a liquid effluent from the gaseous waste by condensing the gaseous waste. The gaseous waste is preferably condensed by cooling it. Plant for implementing the method includes a condenser and a container for collecting condensate. The condenser is preferably a refrigerating device. The plant can further include a soot box.
