HYDRODYNAMICS AND MASS-TRANSFER IN A NEW-TYPE (FG) STACK PACKED EXTRACTION COLUMN

Hydrodynamics and mass transfer experiments were carried out in a 0.1m diameter extraction column with a new type (FG) stack packing develop ed recently in our laboratory. The working systems used were n-Butanol /Succinic acid/water with low interfacial tension of 1.50 x 10(-3)N . m(-1) and 30% TBP (Kerosene)/Acetic acid/water with interfacial tensio n of 10.0 x 10(-3)N . m(-1). Experimental results obtained indicated t hat (FG) stack packed extraction column was proved to possess high thr oughput capacity and excellent mass transfer efficiency. Replacing rot ary discs with FG packings in a lube furfural extraction tower was qui te success with significant economical benefits being claimed.
