Abstract

Experimental study has been carried out in a dual-flow sieve plate scrubber to study the flow characteristics such as dry plate and total tray pressure drop, average clear liquid height and fraction of holes passing gas. The flow characteristics were observed for air ewater system at different gas liquid rates with 8.297 x 10-4 to 27.6 x 10-4 Nm3/s gas flow rates (QG) and liquid flow rates (QL) of 20.649 x 10-6 to 48.183 x 10-6 m3/s. The dry plate pressure drop values are measured experimentally and compared with the predicted values from the existing correlation in the literature. The experimental results of tray total pressure drop and average clear liquid height on tray are plotted against gas load factor (Fs) based on which the flow regimes on present dual-flow sieve plate are discussed. The fraction of holes passing gas values are calculated using correlations available in the literature using average plate pressure drop. The average clear liquid height values from experimental study are matched well with the predicted values of average clear liquid heights from the modified form of clear liquid height correlation.
