Computational fluid dynamic simulation and validation bed expansion of three-phase Co-current fluidized bed

الملخص EN

The bed expansion of gas-liquid-solid co-current fluidized bed is studied in the present work.

Experimental work is carried out using Perspex column having 0.092 m inner diameter, 2 m height.

Kerosene and air are used as continuous and dispersed phases, respectively.

Glass beads having 0.0038 m diameter and 2247 kg/m3 density and catalyst particles having 0.0025 m diameter and 2070 kg /m3 density, which were taken from the kerosene hydrotreating reactor that is located in Al-Daura Refinery, are used as the solid phase.

The Computational fluid dynamic CFD results of dynamic characteristics were obtained based on simulation using commercial CFD codes and ANSYS FLUENT 16.0 have been used for validation, by comparing the simulation and experimental results.

Eulerian approach for flow of granular multiphase is utilized to predict the performance of the three-phase co-current fluidized bed.

The results are indicated that the height of the expanded bed is having a strong function of liquid velocity, which increases as the liquid velocity increases too.
