Pressure swing adsorption
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.
Journal ArticleDOI
Pressure swing adsorption: Development of an equilibrium theory for gas separations☆
Kent S. Knaebel,F. B. Hill +1 more
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.
Journal ArticleDOI
Adsorption breakthrough behavior: Unusual effects and possible causes
Illam Park,Kent S. Knaebel +1 more
TL;DR: In this paper, a mathematical model was developed to simulate the performance of breakthrough curves of unusual shapes, ranging from the expected sigmoidal shape at low humidity to a curve resembling the tangent function, but symmetric about the stoichiometric breakthrough time.
Journal ArticleDOI
Equilibria of nitrogen, oxygen, argon, and air in molecular sieve 5A
TL;DR: In this article, the authors measured pure component equilibrium data for nitrogen, oxygen, and argon, and multicomponent equilibria for air in 20 × 40 mesh 5A molecular sieve.

Pressure swing adsorption system to purify oxygen
TL;DR: In this article, a pressure swing adsorption (PSA) process for splitting oxygen from a feed gas comprising 95% oxygen and 5% argon to achieve an oxygen purity of at least about 99.7% is provided.
