Solid electrolyte ionic conductor systems for the production of high purity nitrogen |
摘要 |
A process for separating a feed gas stream containing elemental oxygen and nitrogen to produce a purified nitrogen gas stream by removing oxygen from the feed gas stream using an ion transport membrane to produce a retentate gas stream and a permeate gas stream, wherein the feed gas stream or the retentate gas stream is purified to remove impurities either before or after the separation step to produce the purified nitrogen gas stream.
