Sensing Strategies for Determining the Axial Gas Dispersion Coefficient in Bubble Columns via Gas Flow Modulation Technique

, 2023
The gas flow modulation technique (GFM) is a recently proposed approach for measuring the axial gas dispersion coefficient in bubble columns. It is based on a time-resolved measurement of the modulated gas holdup at different axial positions in the ...

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

, 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.
