Alf. Porto et al., Hydrodynamics and mass transfer in aqueous two-phase protein extraction using a continuous perforated rotating disc contactor, BIOPROC ENG, 22(3), 2000, pp. 215-218
continuous perforated rotating disc contactor was used to extract bovine se
rum albumin (BSA) with aqueous two-phase systems based on polyethylene glyc
ol (PEG) and phosphate salts. The dispersed phase holdup and mass transfer
coefficient were determined. It was found that the dispersed phase holdup i
ncreased with increasing PEG phase velocity. The overall mass transfer coef
ficient for BSA was independent of the PEG phase velocity.
