Abstract:
A deoxo unit is operated with excess oxygen to produce high purity nitrogen from a partially purified stream passing from a membrane or pressure swing adsorption unit. Essentially complete fuel utilization is achieved in applications in which essentially oxygen-free nitrogen product is not required.
