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

Macedonian 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 ...

Axial dispersion of the liquid phase on a three-phase Karr reciprocating plate column [PDF]

Journal of the Serbian Chemical Society, 2004
The influence of the gas flow rate and vibration intensity in the presence of the solid phase (polypropylene spheres) on axial mixing of the liquid phase in a three phase (gas-liquid-solid) Karr reciprocating plate column (RPC) was investigated. Assuming

DISPERSION IN A TWO-PHASE FLOW SULZER COLUMN

Studia Universitatis Babes-Bolyai Chemia, 2023
An experimental study based on the pulse-response technique was performed in a Sulzer packed-bed column in order to establish the residence time distribution for four different liquid flow rates, namely 200, 400, 600 and 800 L/h and five different gas ...

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.
