Abstract
A skimmer/coalescer system includes a skimmer which skims a two-component liquid from the surface of a liquid mixture in a tank, and a pump which pumps the skimmed liquid to a coalescer for separating and collecting a lower density liquid component from the mixture and returning the rest of the liquid to the tank.
The skimmer includes a housing submerged below the liquid surface in the tank, an outlet operatively connected to the pump and an intake which supplies liquid to the housing by gravity. The intake includes a vertically movable inlet which remains adjacent the liquid surface regardless of liquid level changes in the tank, thereby to skim near the surface where the lower density liquid dominates, and to enhance skimming efficiency. The skimmer also includes a sensor inside the submerged housing which cooperates with the intake to expand or contract the size of the inlet to increase or decrease in-flow to the housing, respectively, depending on whether the liquid level in the submerged housing is receding or raising. This maintains consistent and continuous liquid flow through the system during operation and minimizes the possibility of pump damage.
