Abstract
A turbulent transport contactor is formed by a contacting zone or section with means to introduce lightweight elements and gas at high velocity adjacent one end. Liquid is also introduced to the zone. The high velocity gas entrains the liquid and the lightweight elements and transports them through the contact zone. Means are provided to de-entrain the lightweight elements and a significant portion of said liquid at the end of the contact zone remote from said one end and to return the lightweight elements to said one end for re-introduction into the zone.
