NITROGEN GENERATION SYSTEM

摘要

TITLE NITROGEN GENERATION SYSTEM INVENTOR Bill FREY; Mark HAYNIE; and John PSARAS A PAS (pressure swing adsorber) system for producing high purity nitrogen from compressed air containing a pressure swing dryer to dry the compressed air arranged for regeneration by oxygen enriched desorption eff1uent gasses from the PSA towers. A product notrogen purge assists in desorption of the PSA towers and leads to improved yield. The system is characterized by capability for yields of 99.5% nitrogen plus argon to exceed about 25% and an efficiency of about 60 volumes of the 99.5% product per volume of adsorbent per hour.
