Pressure swing adsorption
01 Jan 1994-
TL;DR: In this paper, a pressure swing adsorption cycle comprised of blowdown, purge, pressurization, feed, pressure equalization and rinse steps provided recovery from an atmospheric air feed, essentially dry and free of carbon dioxide, of a high yield of high purity nitrogen gas and a product gas rich in oxygen.
Abstract: A pressure swing adsorption cycle comprised of blowdown, purge, pressurization, feed, pressure equalization and rinse steps provided recovery from an atmospheric air feed, essentially dry and free of carbon dioxide, of a high yield of high purity nitrogen gas and a high yield of a product gas rich in oxygen as well as recovery of a residual feed byproduct gas for recycle with the air feed.

TL;DR: In this paper, the limitations of the Fick's law for describing diffusion are discussed and it is argued that the Maxwell-Stefan formulation provides the most general and convenient approach for describing mass transport which takes proper account of thermodynamic non-idealities and influence of external force fields.

30 Dec 1968TL;DR: In this article, a pressure-swinging ADSORPT was used for separating gas mixtures in which at least four ADSORBENT BEDS were joined so that the ADSORbate LOADED BED is pressure equalized with two other BEDs in a staggered sequence.

04 Jan 1971TL;DR: In this article, gas mixtures such as air are separated in selective adsorbent beds to produce low-pressure product such as oxygen by simultaneous compressed air-oxygen introduction at opposite ends for partial repressurization, further repressure with only air, and then product oxygen discharge.

15 Oct 1976TL;DR: In this paper, a pressure swing cyclic system was used to remove carbon dioxide and/or hydrocarbon gases, obtaining high recovery of hydrogen at high purity, which can also be employed for separation of methane from admixture with CO2.
Abstract: Hydrogen-containing gas mixtures are subjected to selective adsorption in a pressure swing cyclic system to remove carbon dioxide and/or hydrocarbon gases, obtaining high recovery of hydrogen at high purity. The system can also be employed for separation of methane from admixture with CO2.

TL;DR: In this article, two versions of the pressure swing adsorption process are analyzed as a means for purification of the light component of a binary feed of arbitrary composition, and the results of the analysis show that a critical pressure ratio must be exceeded before complete purification is possible and that this pressure ratio increases as the lightcomponent content of the feed decreases.
