MODIFIED CONTACTOR FOR EXPERIMENTAL STUDIES SF MASS-TRANSFER AND CHEMICAL-REACTION ACROSS A LIQUID-LIQUID INTERFACE

A modified stirred-cell type contactor has been designed and tested fo r its use in experimental investigations of mass transfer and chemical reaction in liquid-liquid systems. Its design overcomes the shortcomi ngs of previously proposed contactors. It is easy to operate and has t he ability to investigate the. effect of a wide range of operating con ditions. The mixing performance of the contactor was tested using a dy e injection and. a tracer technique. Experiments to evaluate mass-tran sfer coefficients across a Liquid-liquid interface have been conducted to determine its effectiveness, The results verified that the contact or could be successfully employed as a useful experimental research ap paratus.
