PRESSURE DROP IN A RANDOM PACKED ABSORPTION TOWER: EXTENDING THE ERGUN EQUATION

PRESSURE DROP IN A RANDOM PACKED ABSORPTION TOWER: EXTENDING THE ERGUN EQUATION

Pressure drop across a packed column in pilot-scale calculated using the Ergun equation that was developed using experimental data from mono-sized, smooth, non-porous, Raschig particles. New values of Ergun equation constants (33.5 and 1.6) which are applicable to this kind of packing, were found to better approximate pressure drop compared to those used in the original form of the Ergun equation (150 and 1.75).
