CFD Modeling and Gas Holdup Measurement in Three-Phase Slurry Bubble Column

Abstract

Gas-Liquid-Solid system as slurry in a reactor have a wide range of applications in industry, a slurry reactor is a vessel containing the catalyst suspended in a liquid phase. In this study, we develop a CFD model to predict the gas holdup at different gas superficial velocities. The experiments were done in a gas-liquid-solid slurry bubble column to find the gas holdup (εG ). The experimental data showed a good agreement with CFD results. An empirical correlation has been developed to predict the gas holdup for three-phase slurry with a correlation co-efficient of 0.994; this correlation shows that the gas holdup predicted was in good agreement with experimental values.
