TL;DR: In this paper, a process for separating nitrogen from gas mixtures containing nitrogen and less strongly adsorbed components such as oxygen, hydrogen, argon or helium by use of an at least binary exchanged X-zeolite having lithium and calcium and/or strontium ions in ratio of preferably 5% to 50% calcium and or stronium and 50% to 95% lithium.

TL;DR: In this paper, a process for separating nitrogen from gas mixtures containing nitrogen and less strongly adsorbed components such as oxygen, hydrogen, argon or helium by use of an at least binary exchanged X-zeolite having lithium and a divalent cation selected from the group consisting of barium, cobalt, copper, chromium, iron, magnesium, manganese, nickel, zinc and mixtures thereof in a ratio of preferably 5% to 50% of the divalent Cation and 50% to 95% lithium.

TL;DR: In this article, the water content of high purity nitrogen obtained by vacuum swing adsorptive fractionation of ambient air, is removed in a companion thermal swing drying system operated in association with the air fractionation system but at independent cycle time period.

TL;DR: In this article, a portion of descending liquid from the distillation section proximate to the location for withdrawing the oxygen-containing side-draw stream is removed from a distillation column and reinserted into the column system at a location proximate the topmost heavies-containing feed to the relevant column.

TL;DR: In this article, an at least binary exchanged X-zeolite having lithium and a divalent cation selected from the group consisting of cobalt, copper, chromium, iron, manganese, nickel and mixtures thereof in a ratio of preferably 5% to 50% of the Divalent Cation and 50% to 95% lithium.
