Abstract:
A purge system, comprising:a process conduit containing a process gas having a vapor pressure; a process gas source connected to the process conduit for supplying the process gas into the process conduit; a purge conduit communicating with the process conduit; an inert gas source comprising inert gas, the inert gas source being adapted to supply inert gas through the purge conduit into the process conduit; a pressure reduction device disposed within the purge conduit, the pressure induction device being adapted to reduce a pressure of the inert gas prior to introduction of the inert gas into the process conduit such that a pressure within the process conduit is maintained below the vapor pressure of the process gas; and a vacuum system for evacuating the process conduit, the vacuum system comprising a vacuum conduit communicating with the process conduit.
