CRYOGENIC HYBRID SYSTEM FOR PRODUCING LOW PURITY OXYGEN AND HIGH PURITY OXYGEN

摘要

A method for producing low purity oxygen and highpurity oxygen using a cryogenic rectification columnwherein feed air is enriched in oxygen in an upstreamadsorbent bed system prior to passage into the columnand refrigeration is generated by turboexpansion ofadsorbent bed effluent or column top vapor.
