A New Type of Packing Apparatus with High Efficiency and the Experimental Research of its Mass-Transfer Performance

Abstract

In this paper, a new type of packing apparatus with high efficiency and uniform flow was developed to deal with wall effect and scaling effect of packed column. A desorption experiment was made in a circular cold-model experiment packed column by using air-water-CO2 as working substance, determining the height of mass transfer unit of liquid phase of the cold-model experiment packed column under different gas-liquid loads, with and without the packing apparatus. The experimental results show that under different spray densities, the height of mass transfer unit of liquid phase of the packed column added with the packing apparatus decreased approximately above 19% more than that not added the packing apparatus; the height of mass transfer unit of liquid phase lowers more with the decrease of the spray density, which demonstrated that the mass transfer efficiency of the packed column added with the packing apparatus was much higher than that of the column not added the packing apparatus.
