METHOD OF PRODUCING HIGH-PURITY PRODUCT FROM INITIAL GAS FLOW CONTAINING ELEMENTAL OXYGEN

摘要

chemistry. SUBSTANCE: initial flow is supplied to one separator having supply zone and permeate zone separated by solid electrolyte membrane. One part of oxygen contained in initial flow is transferred from zone of supply to permeate zone with the help of membrane by supply to permeate zone of reactive blowing flow containing reactive gas which combines with oxygen to obtain lower partial pressure of oxygen in said zone. Retentate with depleted oxygen is withdrawn as a product of high purity. EFFECT: higher accuracy in production of high-quality products. 10 cl, 5 dwg, 1 tbl
