Solid electrolyte systems for producing controlled purity oxygen
摘要:
A process for separating a feed gas stream containing elemental oxygen and at least one other gas into an oxygen product gas stream having a selected concentration of oxygen, by removing the oxygen from a feed gas stream using an ion transport module containing an ion transport membrane having a retentate side and a permeate side to produce both an ultrapure oxygen gas stream emerging from the membrane into the permeate side and a retentate gas stream. The ultrapure oxygen gas stream is blended with an additive gas stream to produce an oxygen product gas stream having a selected concentration of oxygen.
