Continuous Distillation Experiment with Rotating Packed Bed
TLDR
In this article, the performance of a rotating packed bed (RPB) with three kinds of packings was investigated using alcohol/water solution under continuous distillation conditions at atmospheric pressure, and the effects of average high gravity factor (β), reflux ratio (R), and feedstock flux (F) on mass transfer in distillation were examined separately.About:

Analysis of flow in rotating packed beds via CFD simulations—Dry pressure drop and gas flow maldistribution
TL;DR: In this paper, Liu et al. analyzed the impact of gas feed entrance effects on the peripheral gas maldistribution in the rotating packing module and formulated a CFD-based Ergun-type semi-empirical relationship in which the gas-slip and radial acceleration effects, the laminar and inertial drag effects, and the centrifugal effect were aggregated additively to recompose the pressure drops.

Characteristics of a Rotating Packed Bed
TL;DR: In this paper, the mass transfer and pressure drop of a rotating packed bed were investigated under 13−273 equiv of gravitational force with two packings, and the results indicated that the mass-transfer coefficient (KGa) was enhanced due to the centrifugal force as compared to a conventional packed bed.
