- Title
Detection of Microscale Mass-Transport Regimes in Supercritical Fluid Extraction.
- Authors
Salamatin, Arthur A.
- Abstract
The problem of detecting supercritical fluid extraction regimes on the particle-scale level is discussed by using a generalized multiparameter model, which includes the shrinking-core (SC) and broken-and-intact-cells (BIC) approaches as its limiting cases. The model accounts for two internal mass-transfer resistances attributed to cell membranes and transport channels. A wide spectrum of particle-scale extraction regimes, described by the model, agree with available up-to-date relatively short laboratory experiments. Simplified concepts (like SC or BIC) could only be used for available experimental data correlation, and do not allow a reliable extension to long process times. The experimental methodology was suggested to detect limiting internal mass-transfer mechanisms.
