ABSTRACT:
A column of solvent containing foaming contaminants is provided. Gas is injected into the solvent in the column so as to generate foam in the column. Foam generation continues so as to push the foam up in the column, wherein much of the solvent that is in the foam is allowed to drain back down into the column. The drier foam is pushed out of the column and into a container. The foam is broken up into gas and the liquid foaming contaminants. The gas is vented and recirculated for injection into the column for foaming purposes. A portion of the liquid in the container is recirculated as a spray, which spray breaks up the foam. Another portion of the liquid in the container is recirculated into the column as reflux. Another portion of the liquid in the container is removed from the system in order to remove foaming contaminants therefrom.
