Abstract

The concept of relative permeabilities for the gas and liquid phases is used to unify a large number of existing data for liquid holdup and gas phase pressure drops in trickle bed reactors. At relatively high gas flow rates, the liquid and gas phase relative permeabilities are a function of saturation only, and this function is insensitive to the shape of the packing. New data taken at relatively low gas velocities show that the relative permeability can be a function of the gas phase Reynolds number as well as saturation. The nature of this dependence is analyzed using a simple capillary tube model for the concurrent gas-liquid flow in the trickle bed.
