TL;DR: In this paper, an engineering approach is proposed to estimate the shell-side mass transfer coefficient for axial flow in hollow fiber modules with due allowance for the void fraction, which enables one to take the entrance effects of the hydrodynamic and concentration profile into account.

TL;DR: In this paper, the effects of column dimensions, gas velocity and the properties of liquid and solid particles on the gas holdup eG and the volumetric liquid-phase mass transfer coefficient kLa in the solid-suspended bubble column of liquid-solid batch operation were studied experimentally.
Abstract: The effects of column dimensions, gas velocity and the properties of liquid and solid particles on the gas holdup eG and the volumetric liquid-phase mass transfer coefficient kLa in the solid-suspended bubble column of liquid-solid batch operation were studied experimentally. The presence of suspended solid particles in the bubble column reduces values of eG and kLa, and their reduction by an addition of solid particles to the column is high in the transition regime and low in the heterogeneous flow regime. Based on these observations, empirical equations for eG in transition flow and in heterogeneous flow, and an empirical equation for kLa a applicable to the above two flow regimes are proposed.

TL;DR: The present study compared the volumetric mass transfer coefficient (K(tot)A/V(L) of three reactor types; the TBR with 3 mm and 6 mm beads, five different modules of HFRs, and the STR using O2 as the gaseous mass transfer agent.

TL;DR: In this article, transfer coefficients were determined for a number of organic ternary systems and the results compared with the values predicted assuming zero interfacial resistance and using individual transfer coefficients calculated from the correlation derived in the preceding paper.

TL;DR: In this article, the effect of the aqueous and organic flow rates on the overall mass transfer coefficient for extraction was determined and the experimental values of the overall Mass Transfer Coefficient (MTC) for extraction were found in agreement with the ones predicted from the conventional resistance in series model.
