MATERIAL TRANSFER EFFICIENCY IN THE MULTISTAGE PACKED DISTILLATION AND ABSORPTION COLUMNS

Material transfer efficiency by height transfer units and height of equivalent theoretical plate wasinvestigated. Several correlation models have been studied. The overall and individual height oftransfer units were examined. Based on correlation models of the individual phase material transferunits for the gas and the liquid phases the overall material transfer units were determined. Themodels were tested with different systems. The comparative study of the different models which usedfor the prediction of height of transfer units and height of equivalent theoretical plate in packedcolumns. The obtained results show efficiency of material transfer and it using for column designand operation. These results can be used for packing efficiency determination.
