Single drop experiments with liquid test systems: A way of comparing two types of mechanically agitated extraction columns
TLDR
In this article, a comparative analysis between a Kuhni column and a pulsed sieve-plate column is presented, based on the description of the basic mechanisms of drop transport and drop breakage, which are sufficient for the prediction of the global behaviour of the columns, as long as coalescence can be neglected.About:

Extraction of dye from aqueous solution in rotating packed bed
TL;DR: The results suggest that contactor volume required to carry out a given separation can be reduced by an order of magnitude with RPB in comparison to conventional extractors.

Experimental investigation of dispersed phase holdup and flooding characteristics in a multistage column extractor
TL;DR: In this paper, the effects of various parameters including rotor speed and dispersed and continuous phase velocities were studied for determination of holdup, flooding velocity and holdup at the flooding points in a multistage column extractor.

Single drop mass transfer in ternary and quaternary liquid–liquid extraction systems
TL;DR: In this paper, single drop mass transfer data have been obtained for the ternary and quaternary systems toluene-acetone-water and tlueneacetone−phenol-water, and the results were assessed using a simple single solute mass transfer model and a non-equilibrium model based on the Maxwell-Stefan equations.

A Critical Review of the Application of Drop-Population Balances for the Design of Solvent Extraction Columns: I. Concept of Solving Drop-Population Balances and Modelling Breakage and Coalescence
TL;DR: In this paper, the concept of drop population balances is discussed in detail as well as possible solution methods and a critical review of existing models accounting for breakage and coalescence taking place in extraction columns is presented.

Liquid-liquid extraction in a novel rotor-stator spinning disc extractor
TL;DR: In this article, a rotor-stator spinning disc extractor with a spiral-grooved rotor disc and a smooth rotor disc was used for the extraction of phosphoric acid from an aqueous phase to an organic phase.

Description of interaction processes in agitated liquid-liquid dispersions
TL;DR: In this paper, phenomenological models are proposed to describe drop breakup and coalescence in a turbulently agitated liquid-liquid dispersion, and the breakage and rate functions are developed and used to solve the general population balance equation describing drop interactions in a continuous flow vessel.
Shapes and velocities of single drops and bubbles moving freely through immiscible liquids.
Grace,Wairegi T,Nguyen Th +2 more
TL;DR: Grace et al. as discussed by the authors described the shape and velocities of a single drop and a single bubble rising in infinite liquids in the presence of immiscible liquids, and the shape of liquid drops moving in liquid media.

The fall of single liquid drops through water
Shegen Hu,R. C. Kinter +1 more
TL;DR: In this article, the steady motion of 10 organic liquids falling through a stationary water field is discussed and a correlation is presented for nine systems with the exception of the aniline water system, in the form of a single curve relating the drag coefficient, Weber number, Reynolds number, and a physical property group.

Drop sizes in an agitated liquid‐liquid system
Youval Mlynek,William Resnick +1 more
TL;DR: In this article, the relationship between drop size and location in an agitated liquid-liquid system was investigated, with a new sampling method in which the dispersion was sampled in a specially designed trap and immediately encapsulated by a polymer film.

Longitudinal dispersion in pulsed perforated-plate columns
Terukatsu Miyauchi,Haruhiko Oya +1 more
TL;DR: In this paper, longitudinal dispersion coefficients for continuous and dispersed phases and size and holdup of liquid droplets dispersed in the columns are correlated with operating conditions and column design, including the data published by different authors.
