The remaining nitrogen-wealthy gaseous mixture, which is only slightly above liquification temperature, is fed back from output 95 of liquid/gas separator 90 via the heat exchanger 80 at input 82a into cooling pass 82b. The outputs 65 and 66 are connected in fluid communication to the input 72 of a third non- speak to water-to nitrogen aftercooler 70. Portions of the nitrogen gas in higher stress gaseous nitrogen pass 81 are taken off at output 83b to input 69b of…
