Mass Transfer Performance of a Novel Structured Packing for Liquid-Liquid Extraction

Abstract:

The flow pattern of the dispersed phase through three types of packings, 700Y rhombus mesh frame packing (RMFP), 350Y polypropylene corrugated sheet packing (PPCSP) andФ16mm plum flower mini ring (PFMR), was observed. According to the characteristics of solvent extraction, a novel hybrid structured packing, consisting of 700Y RMFP and 350Y PPCSP, was developed for liquid-liquid extraction. The mass transfer efficiencies of the novel hybrid structured packing andФ16mm PFMR were investigated in a 150mm diameter column, working with the 30% tributyl phosphate-kerosene (dispersed phase) / acetic / water (continuous phase) system. It is found that the apparent height of mass transfer unit of the hybrid structured packing is 21% smaller than that ofФ16mm PMFR in average under the same experimental condition. It can be concluded that the hybrid structured packing is a high-efficiency packing for liquid-liquid extraction.
