H. Lohner et al., CHARACTERIZATION OF DROPLETS IN LIQUID-LIQUID-EXTRACTION BY LASER-OPTICAL MEASUREMENT TECHNIQUES, Chemical engineering & technology, 21(4), 1998, pp. 337
The determination of process parameters, like droplet diameter and vel
ocity or mass transfer rates, is fundamental for the modeling and desi
gning of the liquid-liquid extraction process. In this context, phase-
Doppler anemometry (PDA) and rainbow refractometry (RBR) offer improve
d and unexpected possibilities of droplet characterization in liquid-l
iquid systems.
