Liquid-liquid separation apparatus

摘要

Apparatus is disclosed for separating a multiphase liquid mixture of lighter and heavier liquids which includes a caisson into which the liquid mixture is introduced. A surge plate extends horizontally across the interior of the caisson dividing it into upper and lower sections. The lower section forms a reservoir for receiving the liquid mixture. A wier plate extends vertically from the surge plate forming a reservoir and a spillover bucket chamber in the upper section for the lighter liquid. An opening in the surge plate communicates the lower and upper section reservoirs. Means are provided for supplying liquids to the lower section reservoir and for removing the lighter liquid from the bucket chamber.
