Modified Contactor for Experimental Studies of Mass Transfer and Chemical Reaction across a Liquid—Liquid Interface

摘要

A modified stirred-cell type contactor has been designed and tested for its use in experimental investigations of mass transfer and chemical reaction in liquid—liquid systems. Its design overcomes the shortcomings of previously proposed contactors. It is easy to operate and has the ability to investigate the effect of a wide range of operating conditions. The mixing performance of the contactor was tested using a dye injection and a tracer technique. Experiments to evaluate mass-transfer coefficients across a liquid—liquid interface have been conducted to determine its effectiveness. The results verified that the contactor could be successfully employed as a useful experimental research apparatus.
