Abstract:
The present invention is a nitrogen pressure swing adsorption process for separating gas mixtures containing nitrogen and oxygen, such as air, using a unique gas transfer process step, continuous feed gas introduction and an appropriate isolation step with continued product purge/repressurization to achieve high purity nitrogen product of 99.9% or greater by volume nitrogen, preferably 99.99% or greater by volume of nitrogen.
