A review of mathematical modeling of fixed-bed columns for carbon dioxide adsorption
TL;DR: A review of efforts over the last three decades toward mathematical modeling of the fixed-bed adsorption of carbon dioxide can be found in this paper, where a comprehensive mathematical model consists of coupled partial differential equations distributed over time and space that describe material, energy, and the momentum balances together with transport rates and equilibrium equations.

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.

Air separation by pressure swing adsorption on a carbon molecular sieve
TL;DR: In this paper, a simplified dynamic model for a PSA air separation process based on linearized mass transfer rate expressions and binary Langmuir equilibrium is developed, which provides a good representation of the experimentally observed behaviour over a wide range of conditions.
Journal ArticleDOI
Numerical simulation of a pressure swing adsorption oxygen unit
TL;DR: In this article, a numerical model was developed to simulate the kinetic separation of air in a carbon molecular sieve pressure swing adsorption unit, which was extended to the equilibrium selective separation over a zeolite adsorbent in which nitrogen preferentially adsorbed, leaving oxygen as the pure raffinate product.

Equilibrium theory of a pressure swing adsorption process
TL;DR: An equilibrium theory of the separation of two-component gaseous mixtures via the pressure swing adsorption process known as heatless adaption is presented in this paper, where principal predictions for the condition of complete removal of the trace component from the high pressure product stream when using the least possible amount of adsorbent are as follows.
