PROCESS FOR THE PRODUCTION OF HIGH PRESSURE NITROGEN WITH SPLIT REBOIL-CONDENSING DUTY |
摘要 |
A process is set forth for recovery of nitrogen from a feed gas stream, containing nitrogen and oxygen, using a cryogenic separation wherein a recycle stream having an oxygen content above, equal to or below that of the feed gas stream is recycled from the cryogenic separation to the feed gas stream with a split reboil-condenser function that would allow variation of the oxygen content of the recycle stream. |
