Abstract
Methods for recovering and recycling helium and unreacted chlorine from a process for manufacturing optical fiber are disclosed. Helium-rich and chlorine-rich gas streams are recovered from the consolidation furnace and separated. The helium-rich stream is dried and blended with make-up helium and the chlorine-rich stream is purified and blended with make-up chlorine so that each may be reused in the optical fiber production process.
