Abstract

Sieve trays have become popular contacting devices for the mass and heat transfer applications because of their relative simplicity and low cost. As a result, much has been published in the recent years on their hydraulic and mass transfer performance. However, little has appeared on improving contact performance by adding a shallow bed of packing on the trays. The purpose of this study is to determine the effect of installing a thin layer of mesh packing on the performance of sieve trays under distillation conditions. Since the installation of mesh packing can be easily carried out at a low cost, this could provide the best method to revamp existing sieve tray columns. This type of arrangement is termed as packed-tray. The Acetone-water system is chosen for the study so that the result could be applied to aqueous as well as organic system. This study is initiated with the objective of developing a computer program that can be use to predict, design and to determine the influence of such packings on the hydraulic and mass transfer performance of sieve trays. The results of the program are further used in the separation of multicomponent mixture, and a computer program was developed for the solution of the same mixture. During the course of the study, several novel ideas for improving the contact performance of conventional sieve-tray were studied.
