| 中文摘要 | Volumetric liquid-liquid mass transfer coefficients ( k _La) were determined for liquid-liquid-solid dispersion in a mechanical ly agitated baffled tank by using a conductivity probe.The effects of agitation speed, inert glass bead or PET particle diameter, type of impeller, impeller-to -bottom clearance, and the solids mass fraction on the mass transfer of the typ ical liquid-liquid extraction system (n-butanol-deionized water-succinic acid) were studied. The experimental results indicated that k_La incre ased in liquid-liquid and liquid-liquid-solid systems when agitation speed in creased. The addition of glass beads enhanced the liquid-liquid mass transfer c oefficients, but PET particles decreased the mass transfer rate. In both liquid -liquid and liquid-liquid-solid systems, the Rushton impeller is the most eff icient one for mass transfer. The mass transfer coefficient showed a maximum in glass beads systems but decreased slightly in PET systems as the fraction of so lid phase increased.For the Rushton impeller, k_La showed a minimum for glass beads systems and increased linearly with the increase of clearance for P ET particles. |
