ABSTRACT:
A mixture of a first liquid of one density and a second liquid of a different density and which is substantially insoluble in the first liquid is separated by flowing the mixture through a gravity settler tank where the mixture separates into a clear upper layer of the lighter liquid, a clear lower layer of the heavier liquid, and an intermediate layer of uncoalesced droplets of one of the liquids dispersed in a continuous phase of the other at the interface between the upper and lower layers. Clear liquid from the upper layer is withdrawn through an overflow, and clear liquid from the lower layer is withdrawn through an underflow. An impediment or baffle extends across the settler tank transversely to the direction of liquid flow, and is disposed in the intermediate layer of the mixture of the two liquids to impede the flow of the intermediate layer away from the tank inlet.
