Abstract:
A method for recycling helium utilized in an optical fiber manufacturing process, comprising the steps of:feeding helium of a first level of purity to the optical fiber manufacturing process;recovering waste helium from the optical fiber manufacturing process;feeding recovered waste helium to a helium purifier;purifying the recovered helium utilizing the helium purifier to produce an output stream of recycled purified helium;checking a purity of the recycled purified helium; anda) feeding the recycled purified helium to a holding tank if the purity meets a process requirement for the optical fiber manufacturing process, orb) venting the recycled purified helium if the purity does not meet the process requirement for the optical fiber manufacturing process.
