Mass Transfer During Droplet Formation – A Measuring Technique Study

Heine, Jens S. / Bart, Hans‐Jörg

In liquid‐liquid extraction processes, the mass transfer coefficient is one of the key design parameters. In the present study, the impact on mass transfer during droplet formation in a quiescent continuous phase is investigated analytically. Therefore, confocal Raman spectroscopy in a novel measurement cell combined with interfacial tension measurements are applied. It could be shown, that Marangoni effects in the system toluene‐acetonitrile‐water (mass transfer direction from the dispersed to the continuous phase) lead to 50 % of mass transferred in the first 5 s when 90 % is transferred in 1 min.
