    摘要: This invention is directed to a method, and a system therefor, for recovering PFC using condensation by passing a PFC-containing feed stream into a condenser, preferably reflux condenser, to effect liquefaction into a PFC-containing condensate and a carrier gas stream, and passing the PFC-containing product into a mass transfer unit to fractionate the PFC-containing condensate into a high volatility PFC stream and a PFC product.
