Zusammenfassung:	IMPROVED MEMBRANE NITROGEN PROCESS AND SYSTEM Feed air is separated in a membrane system, with recovered nitrogen being purified in a deoxo unit and dried in an adsorbent dryer using high temperature purge gas. The heat generated in the deoxo unit can be used to satisfy the thermal energy requirements of dryer regeneration, without decrease in product recovery. Membrane permeate gas can be used for purge at high purge/feed ratio to reduce the energy requirements of bed regeneration. D-16149
