Parametric Pumping: Separation of Mixture of Toluene and n-Heptane.
Parametric pumping, a dynamic separation technique, comprises alternating axial displacement of a fluid mixture in a column of adsorptive particles upon which a synchronous cycling temperature is imposed. With direct coupling, separations of 10(5):1 between column ends have been obtained, with indications of great potential for further separation. A mathematical model and its solution describe the behavior of the system.
