Analysis of breakthrough curves: effect of mobile and immobile pore volumes

Abstract

A new technique of evaluating readily displaceable liquid has been outlined. The use of this technique has been illustrated for several breakthrough curves, highlighting the deviations in earlier estimates of pore volumes which are either positive or negative. The implication of these deviations has been discussed. The effect of this change in pore volume on Peclet number is presented. The prediction made with the new set of parameters is illustrated and compared with the observed data resulting in an overall improvement in predictions.
