Abstract
Liquid–liquid extraction of the recommended test system, cumene– iso butyric acid–water (CBW) as a typical example of liquid–liquid extraction processes has been carried out in a new two-opposed-jets contacting device (TOJCD). The experimental results clearly indicate that TOJCD provides much higher overall volumetric (capacity) mass transfer coefficients, K L a, than those of conventional extractors. This high overall volumetric (capacity) mass transfer coefficient, K L a, indicates greater performance capability of TOJCD relative to those of conventional contactors. In addition, the effects of the upper disk speed, solution flow rate, disk diameter, and the distance between disks on the extraction efficiency have been investigated. Furthermore, the effectiveness of two-opposed jets was evaluated by employing another new non-opposed-jets contacting device.
