The extended crossflow model was proposed earlier 5 to account for the role of the stagnant zones of liquid in a packed trickle bed during absorption with a chemical reaction. Here the model is applied to a second order reaction to investigate the behaviour of the effectiveness f of the interfacial area of the static hold‐up during absorption with a chemical reaction. General criteria are developed which give conditions for the limiting behaviour of f for reaction kinetics of any form. Finally, a possible pitfall is described in detail which must be avoided in conducting kinetic experiments in a packed trickle bed.
