Gas Holdup and Liquid-Phase Dispersion in Packed Bubble Columns

open access: yesTikrit Journal of Engineering Sciences, 2011
The gas holdup and liquid phase axial dispersion coefficient are measured in two semi batch packed bubble columns, 10 and 15 cm diameter for an air–water system, at atmospheric conditions.

Hydrodynamics in spray and packed liquid-liquid extraction columns: A review

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2019
This work provides a review of hydrodynamic characteristics such as the slip velocity, the dispersed-phase holdup, mean drop size, and axial dispersion of non-mechanically agitated liquid-liquid (L-L) extractors, with special reference to spray and ...

Generalized semi-opened axial dispersion model [PDF]

open access: yes, 2012
The axial dispersion model (ADM) is studied and then generalized by a new form of the left boundary condition of semi-open flow system. The resulting parameter driven model covers the traditional axial models: axial closed-opened dispersion model with ...

Axial Dispersion in a Pulsed and Nonpulsed Disc and Doughnut Solvent Extraction Column [PDF]

open access: yes, 2017
In solvent extraction columns mechanical agitation is usually introduced to improve the extraction efficiency. However, some industrial columns have been found to have higher extraction efficiency while running with no pulsation.
