Supercritical fluid extraction is a process in which a solute is separated from a solid matrix generally from a packed bed such as in the case of coffee, tea, oilseeds and other applications as highlighted in Chapter 4.Mass transfer tells one how long that it will take for a solute to be removed from a solid matrix. There are many mass transfer models.
