Critical design parameters reproduced from Inglezakis and Poulopoulos (2006).
|L/dp||Minimal effect if it is higher than 150|
|L/D||Minimal effect if it is greater than 5|
|D/dp||Minimal effect if it is higher than 30 and geometrical similarity can be ignored|
|Rep||Minimal effect if L/dp > 150|
|Ε||Minimal effect if dp/D& <& 0.1|
|Us||Minimal effect if solid diffusion is rate-controlling and if the unit operation is in up-flow mode|
