ABSTRACT:
An apparatus for performing liquid-liquid contacting operations, such as the extraction of mercaptans from hydrocarbons. The apparatus comprises a metal sphere which is retained in position above a mating valve seat in the upper open end of a vertical collar by a vertical retention cage. The collar extends through a horizontal plate, and a first liquid passes upward through a vertical bore in the collar to lift the sphere and contact a second liquid retained above the horizontal plate.
