Phase disengagement in liquid-liquid contactors.

摘要

A liquid-liquid contactor has a column 10 of conventional form with a phase-disengaging zone 20 at the base of the column 10. A dispersion band 22 forms at the interface between the phases in the zone 20, and stress wave energy is applied to the band 22 from an ultrasonic transducer 24. Standing wave conditions are produced in the region of the band 22, and the amplitude of the transducer 24 is adjusted such that coalescence is favoured and the width x of the band 22 is reduced.
