Parametric pumping is a separation process characterized by periodic changes in axial displacement, coupled with synchronized changes in some variable affecting the position of the interphase equilibrium. Both continuous and semicontinuous pumps were investigated at various operating conditions using a model system of toluene-n-hep-tane on a silica gel adsorbent. It has been shown that when the penetration distance for the cold cycle is less than or equal to that for the hot cycle and the height of the column, the pump has the capacity of complete removal of solute from one product stream. A quantity which is important in determining pump performance is the equilibrium parameter, b. Pump performance is enhanced by large interphase movement and hence by large values of the equilibrium parameter.
