Hydrodynamics of Extraction Devices:Residence Time Distribution in Centrifugal Extractors for Organic Phase

摘要

Annular centrifugal extractors (ACEs), also known as centrifugal contactors or annular centrifugal contactors, are one of the most effective devices for liquid-liquid extractive separations. ACEs, consisting of a high-speed rotor positioned inside a stator, accomplish mixing and separation of phases in very short residence times. Additional advantages of ACEs include rapid approach to equilibrium and steady state, and high mass transfer rates in a compact volume [ 1 ].
