TL;DR: In this article, the authors investigated the effect of the oil phase on the bubble-to-emulsion mass transfer coefficient and showed that the effect is independent of the volume fraction of n-alkans and oleic acid.

TL;DR: This specifically designed protocol can provide key information regarding the kinetic performance of columns used in liquid chromatography and explain why different columns behave so differently.

TL;DR: In this article, a non-equilibrium (NEQ) model for packed reactive distillation columns is proposed. The important features of the model are the use of the Maxwell-Stefan equations for description of intraphase mass transfer and incorporation of a homotopy-like continuation method that allows for easy tracking of multiple steady states.

TL;DR: In this paper, reversible entropy generation for combined forced convection heat and mass transfer in a two-dimensional channel is investigated, and the authors obtain the entropy as a function of velocity, temperature, concentration gradients and the physical properties of the fluid.

TL;DR: In this paper, effective interfacial area (ae) and liquid side mass transfer coefficient (kL) were investigated in a rotating packed bed (RPB) contactor with 5 novel rotors equipped with blades in the packing section and 1 conventional rotor without blades and fully filled with the same packing.
Abstract: In this work, gas–liquid mass transfer characteristics, such as effective interfacial area (ae) and liquid side mass transfer coefficient (kL), were investigated in a rotating packed bed (RPB) contactor with 5 novel rotors equipped with blades in the packing section and 1 conventional rotor without blades and fully filled with the same packing. The chemisorption of CO2 into a NaOH solution was used to evaluate ae and kL within each rotor of the RPB. The experimental results indicate that the rotors with blades can significantly intensify the mass transfer process at all rotational speeds, over a range of gas–liquid ratios. The mass transfer rate achieved within these novel rotors was between 8% and 68% higher in comparison with the conventional rotor. A model based on the Danckwerts surface renewal theory was developed to calculate the liquid side volumetric mass transfer coefficient (kLae) in the rotor. The experimentally obtained values of kLae are in agreement with model predictions within ±15%.
