TL;DR: Mass transfer models on supercritical carbon dioxide extraction of vegetable oils are reviewed, that may facilitate the scale-up of laboratory data for industrial design purposes and the role of the solid matrix on high-pressure phase equilibrium is given.
Abstract: Mass transfer models on supercritical carbon dioxide (SC-CO 2 ) extraction of vegetable oils are reviewed, that may facilitate the scale-up of laboratory data for industrial design purposes. Reviewed mechanisms of oil transport within the solid matrix include the desorption from the solid, the formation of a shrinking core of condensed oil in a non-adsorbing porous matrix, and diffusion in a homogenous medium. Analyzed simplificat ions of a general mass transfer model include external control of mass transfer rates, internal control of mass transfer rates, consideration of a linear driving force, and steady state approximations, among others. More complex two-stage models, and critical comparisons of some of the proposed models are also included. Trends for the external mass transfer coefficient and effective diffusivity in the solid matrix from studies on SC-CO 2 extraction of oil from vegetable substrates are thoroughly discussed and contrasted with those obtained using simpler model systems. The possib...

TL;DR: In this paper, a model was established to illustrate the mechanism of gas-liquid mass transfer with reactions in rotating packed bed at higher gravity level, and experiments were carried out at various rotating speeds, liquid flow rates, gas flow rates and temperatures in RPB with Benfield solution as the absorbent.
