Gas-Liquid Mass Transfer using Advanced Optical Probe in a Mimicked FT Slurry Bubble Column

Abstract

Gas-liquid volumetric liquid-phase mass transfer coefficient (kLα) was studied in a slurry bubble column at the conditions mimicking Fischer-Tropsch synthesis. To avoid the hydrodynamic disturbances due to the gas switching, oxygen enriched air dynamic absorption method was used. Influence of reactor models (CSTR, ADM and RCFD) on the volumetric mass transfer coefficient was investigated. Effect of operating pressure, superficial gas velocity and solids loading were investigated. From the reactor models investigated, it is recommended to use ADM model for kLα study. If the CSTR model is used, applicability of the model should be checked. With increase in the superficial gas velocity and operating pressure, volumetric liquid-phase mass transfer coefficient increases, while it decreases with the solids loading corroborating with the literature.
