Equilibrium Parametric Pumps

Abstract

Semicontinuous and continuous pumps were experimentally investigated at various operating conditions. The model system used was toluene-n-heptane on 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 a large value of b.
