14.5 Supercritical Fluid Extraction

There has been an increasing amount of interest in the use of supercritical fluids (SCF) for leaching or extracting compounds from solids or liquids in the food and pharmaceutical industries because of the nontoxic nature of the primary SCF—carbon dioxide. In this section we will briefly consider the properties of SCFs that make them interesting for extraction. Then a typical process for SCF extraction will be explored and several applications will be discussed.

First, what is an SCF? Figure 14-6A shows a typical pressure-temperature diagram for a single component. Above the critical temperature Tc, it is impossible to liquefy the compound. The critical pressure pc is the pressure required to liquefy the compound ...
