Abstract: | This study is mainly comprised of evaluating mass transfer coefficient from the volumetric flux and protein transmission
data in a thin channel flow module. Dilute solutions of lysozyme were ultrafiltered through hydrophilic membrane (cellulose
acetate type) with molecular weight cut off (MWCO) of 30,000. Experiments were performed in thin channel flow (TCF10)
configuration and data for transmission and volumetric flux obtained as a function of pressure and cross flow velocity. The
results were analysed keeping into account the formation of Dean vortices and it was seen that the presence of Dean vortices
gave better performance in terms of mass transfer. The mass transfer coefficient obtained with Dean vortices was comparable
with the other commercial cross flow system involving secondary flow like Taylor vortices. A new mass transfer correlation
has also been presented and compared with the reported correlations in literature. |
