i am a third year chemical engineer student tasked to design a Pressure swing adsorption column
i came across the "how to guide for adsorber design" and im relying on this guide to design my column as it is difficult to obtain information regarding designing a PSA column.

Anyways in the guide there is a discussion on selectivity , and i would like to know where can i find more information about it or how to calculate the "selectivity" (I dont know what is Ai and Aj, refer to attachment). I have attached the equations and the guide in question.

Information on my design.

Removal of carbon dioxide using zeolite 13x using 2 bed PSA
adsorption isotherm used is the Langmuir Freundlich isotherm
