TL;DR: In this paper, the authors investigated sedimentary organic matter, in particular coals, as a potential source of molecular nitrogen in the subsurface and concluded that the amounts of gas encountered in nitrogen-rich gas accumulations represent only a small fraction (possibly < 1 %) of the total gas generation potential of this area while the bulk of the generated gas has escaped to the atmosphere.

7 Nov 1975TL;DR: In an adiabatic pressure swing process for separation of feed gas mixtures such as H 2 containing CO 2 and N 2 impurities, at least seven adsorbent beds are employed of which at least two are receiving feed gas during the entire cycle, and with at least three pressure equalization stages as mentioned in this paper.

TL;DR: In this article, a method and system for separating carbon dioxide (CO 2 ) from a C02 containing gas stream containing water vapor and additional impurities, for example, nitrogen, oxygen, sulfur oxides, nitrogen oxides and mercury.
Abstract: Disclosed herein is a method and system for separating carbon dioxide (CO 2 ) from a C02 containing gas stream containing water vapor and additional impurities, for example, nitrogen, oxygen, sulfur oxides, nitrogen oxides, and mercury. The C02 is captured by subjecting the CO 2 gas feed stream to a temperature swing adsorption step. The temperature swing adsorption step comprises an adsorption step for producing a substantially dry carbon dioxide-depleted stream, and an adsorbent regeneration step comprising heating the adsorbent bed to produce a substantially water vapor-free carbon dioxide stream. Moisture from the gas stream containing CO 2 is optionally removed by pressure swing adsorption, temperature swing adsorption, membrane separation, or absorption prior to CO 2 capture.

TL;DR: In this paper, a pressure swing adaption process for the separation of nitrogen from natural gas utilizes two separate pressure swing adsorption stages, the first containing a hydrocarbon-selective adsorbent and the second containing a nitrogen-selectively ada-tent.
Abstract: A pressure swing adsorption process for the separation of nitrogen from natural gas utilizes two separate pressure swing adsorption stages, the first containing a hydrocarbon-selective adsorbent and the second containing a nitrogen-selective adsorbent. In the process, the product stream from the first pressure swing adsorption unit contains a natural gas stream having a reduced hydrocarbon content and the product stream from the second pressure swing adsorption unit is a natural gas stream having a reduced nitrogen concentration. The product from the second pressure swing adsorption unit is used to desorb the hydrocarbons from the first pressure swing adsorption unit so as to add the hydrocarbons, which have heat value to the product natural gas stream. Periodically, heating the nitrogen-selective adsorbent with heated product stream from the second pressure swing adsorption unit has been found to improve the capacity of the nitrogen-selective adsorbent to adsorb nitrogen.
