An electrically driven multistage countercurrent solvent extraction device: the emulsion-phase contactor

The dynamics of ultrasonically levitated drops in an electric field

“…This is relevant to applications in industrial processes involving solvent extraction and direct contact heat exchangers. [1][2][3] At the same time, progress in levitation technology has introduced the possibility of investigating the properties of materials in the liquid state under conditions only obtainable for levitated samples. 4 -6 In this context, the accuracy of measurements of the surface properties of acoustically, electrostatically, or electromagnetically levitated melts depends on our knowledge of the often nonlinear dynamics of the droplets.…”

The Electrodynamic Contactor for Extraction

“…Data from Oak Ridge National Laboratory using the resonant frequency technique 17 have demonstrated the effectiveness of the electrostatic contactor as compared to conventional techniques. Data for the transfer of acetic acid between water and methyl isobutyl ketone in the Emulsion Phase…”

Effects of low-amplitude forced oscillation on the rate of mass transfer to circulating liquid droplets

“…Experiments have been carried out in two general areas: (1) the use of high-amplitude oscillations, which lead to droplet breakup and/or emulsification (Scott, 1987;Scott and Sisson, 1988;Scott and Wham, 1989) and (2) the use of stable oscillations for the alteration of velocity profiles (Scott, 1986;Wham and Byers, 1987;Scott et al, 1990).
