Influence of mass transfer direction on the performance of pulsed packed column

An experimental investigation has been carried out in order to determine the influence of mass transfer direction on the operation of pulsed packed column. The ternary system that studied was water-acetone-toluene as recommended by the E.F.C.E. In this paper the influence of mass transfer direction on hold-up, drop size, interfacial area and overall mass transfer coefficient is investigated. It was observed that the dispersed phase hold-up in the c→d transfer is greater than that in the opposite direction and c→d transfer tends to produce smaller drops. Also, from a practical point of view, it was found that the overall mass transfer coefficient in the case of d→c mass transfer direction is higher than that in opposite direction, in spite of a lower interfacial area.
