Hello all and thank you for letting me join your forum!

 

I'm a student of chemical engineering and for a piece of project work I've got to design a PSA system to generate nitrogen.

 

I need 0.144 kg/s of N2 and 99.99% molar purity and the design is giving me headaches! I know that at this purity PSA may not be the strictly most economic option however for the sake of simplicity in design I've decided to stick with it.

 

The first issue comes with modelling - the models in the literature (eg Hassan 1986) are complicated and I'm struggling to implement them on MATLAB (my only available software package - no Aspen dynamics here). At any rate they fail to predict the high (but possible) product purity rates so are of limited use.

 

So how on earth does one go about designing a kinetically controlled PSA process? I've found nothing of much use in textbooks, even Ruthven et al.'s seminal 'Pressure Swing Adsorption'.

 

Any advice would be hugely appreciated, many thanks.

hi ,

 basic documents about PSA and N2 .

Hope this helps a bit.
