摘要
Hydrodynamics and mass transfer experiments were carried out in a 0.1m diameter extraction column with a new type (FG) stack packing developed recently in our laboratory.The working systems used were n-Butano1/Succinic acid/water with low interfacial tension of 1.50×10-3N·m-1 and 30% TBP (Kerosene)/Acetic acid/water with interfacial tension of 10.0×10-3N· m-1. Experimental results obtained indicated that (FG) stack packed extraction column was proved to possess high throughput capacity and excellent mass transfer efficiency. Replacing rotary discs with FG packings in a lube furfural extraction tower was quite success with significant economical benefits being claimed.
1 INTRODUCTIONOne of the major objectives in the study of extraction column is to minimize column di-mensions to fulfill a certain specific separation process.This has led to the intensiveemployment of structured packings in extraction columns [1].One of the recentdevelopments targeted for greater interfacial areas without excessive dispersion is the useof structure packings contactive claiming advantages,such as lower fluid flow
