Fluid Dynamics in a Continuous Pump-Mixer
Applied Sciences, 2022 The fluid dynamic (flow rates) and hydrodynamic behavior (local droplet size distributions and local holdup) of a continuous DN300 pump-mixer were investigated using water as the continuous phase and paraffin oil as the dispersed phase.

Holdup of dispersed phase in a mixer-settler extraction column.
JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1990 Holdups in a stirred liquid-liquid dispersion were measured in a single-stage mixer-settler column equipped with a lifter turbine impeller. There was a large difference in dispersed phase holdup between the local positions above and below the impeller.

Reciprocating plate column - fundamental research and application in Serbia from 1970 to 2020 [PDF]
Hemijska IndustrijaIn the group of multiphase contactors and reactors, an important place belongs to reciprocat-ing plate columns (RPCs), which consist of a set of perforated plates fixed on a carrier (the so-called reciprocating or vibrating agitator) moving periodically ...

Hydrodynamics of gas-agitated liquid-liquid extraction columns [PDF]
Acta Periodica Technologica, 2012 Although the non-agitated extraction columns (spray column, packed column, perforated plate column, sieve plate column, etc) can handle high flow rates and are simple and cheap, there have been relatively few applications of these columns because they

Comparative Analysis of Riser Base and Flowline Gas Injection on Vertical Gas-Liquid Two-Phase Flow
Energies, 2022 Gas injection is a frequently used method for artificial lift and flow regime rectification in offshore production and transportation flowlines. The flow behaviour in such flowlines is complex and a better understanding of flow characteristics, such as ...
