Ae. Kostanyan, Comparison between various schemes of three-phase extraction: Mass transfer between two liquid phases through an exchange medium, THEOR F CH, 33(6), 1999, pp. 584-592
Indirect (contactless) mass transfer between two phases through a transfer
medium (in processes with liquid membranes and in sequential extraction-ree
xtraction) was considered. Various flowsheets of mass transfer in a three-p
hase liquid system with continuous and periodic contacts between the phases
were analyzed.
