Dear Sir/Madam,


I wish to implement adsorption calculation in excel. I am trying to model moisture and CO2 separation from air by molecular sieve-13X so to study kinetic leak and breakthrough curve.


I am trying to implement Advection-diffusion-dispersion-reaction coupled partial differential equation in excel VBA by methods of line. Here I am assuming linear driving force and Langmuir isotherm model.


If anyone can kindly share vba code to solve partial differential equation by method of line or any finite difference methods that would be very helpful (may not be related  particular to my case also be helpful).


I have all mass transfer data, isotherms etc but unable to implement it in excel by VBA.



Thank you,
