Dispersed-phase holdup and mass transfer in a rotating disc contactor with perforated skirts

Dispersed-phase holdup and extraction efficiency were measured in a pilot-plant scale rotating disc contactor (RDC) with perforated skirts (RDCS) with kerosene-o-cresol-water system. The data for the RDCS were examined using the data in this work and the available correlations proposed for the plain RDC. A comparison between the data measured in the RDCS and those in the RDC indicated that the RDCS has rather better extraction efficiency compared with the RDC.
