Where can I find references on regeneration of adsorption beds?

Question

For a chemical plant design project for school - I need to find a method to calculate the necessary duty, airflow, and time to regenerate a bed of 3A molecular sieves used to dehydrate a fluid flow. Patent and literature searches have been hit-and-miss for me so far, most just say it takes a few hours with little data behind it. Could point me towards any good resources for this?

Answer 1

You need to do some thermo-calculations.

How big a bed? What is the state of the regenerating air? This will determine an estimate.

Then you will have to experiment to see if you have any efficiency issues, and you will need a contingent in case you do (if there are inefficiencies, does raising the temp of the regenerating air by 10° C help...?)
