ABSTRACT
Pressure drop is an important design parameter in the three-phase flow. The influence of pressure seems to be higher on the heterogeneous reactive system than in the homogeneous reactive system. The liquid phase properties have an immense effect on the pressure and liquid axial dispersion coefficient. The gas-interacting three-phase pressure drop is an essential element for the design of process which is the subject of numerous experimental and numerical studies. The distributor affects the pressure energy distribution in the slurry reactor based on the distribution of the phase hold-up in the reactor. In the downflow gas-interacting slurry reactor, the friction factor depends on different operating variables. The decrease in gas hold-up increases the hydrostatic pressure and consequents the decrease in frictional pressure drop in the column. One of the most widely used recognized tools to describe the three-phase pressure drop in different process equipment is Lockhart—Martinelli correlation.
