Process and apparatus for directly contacting two counterflowing immiscible liquid phases

摘要

A process for contacting two counterflowing immiscible liquid phases in a column in which perforated plates define mixing zones and separating zones and in which each mixing zone receives a heavy-liquid phase entering through perforations from above and a light-liquid phase entering through perforations from below and a dispersion formed by the two liquid phases in each mixing zone is transferred from the latter into a juxtaposed separating zone from which the heavy-liquid phase is withdrawn downwardly through perforations and the light-liquid phase is withdrawn upwardly through perforations. The dispersion is contacted in the separating zones with a filling of a material which accelerates coalescence.
