A new, improved pressure drop correlation for trickle-bed reactors

Abstract Presently-available pressure drop correlations for trickle-bed reactors are not applicable over wide ranges of system conditions. The new, improved correlation for the pressure drop in a trickle-bed reactor presented here - derived from fundamental considerations and a wide-ranging data base of some 4600 hydrodynamic experimental results - is applicable to industrial trickle-bed reactors since it is based on wide variations of all the important variables, including measurements at high pressures. No other previously derived correlations are applicable to high pressure operations.
