Modelado de los fluidos supercríticos
Resumen
Se describen las ecuaciones matemáticas más empleadas en el modelado
de procesos convencionales de extracción de diferentes principios activos,
presentes en materias primas de la agroindustria. Se muestra su utilidad en
la predicción de la solubilidad de estos principios activos en fluidos
supercríticos, especialmente en el CO2 supercrítico.
