Experimental study of liquid distribution in packed column

Abstract

This work presents the results of an experimental study ofIiquid distribution for the air/water system, carried out in 0.3m diameter Perspex column packed with 25mm plastic pall rings of equal length and diameter. Measurements of flow rates were performed at different radial and axial positions at the end of the column. The column was operated with gas flow rates varying over the ranges of 0.0 to 1.2kg/m2s, liquid flow rates varying over the range 9.9 to 19.9kg/m2s and with the ratio of the initial flow to the bulk and wall regions varying between O. 8 and 0.5. The packing height was increased by the addition of a fixed amount at a time, until a height of 1.05m was reached.
