Abstract

A pair of chambers each containing a body of liquid are separated by a single heat-conducting partition wall. A guide wall is parallel to and spaced from each side of the partition wall and steam is bubbled up between the two walls to recirculate the liquids in the chambers and thereby effect heat exchange through the wall. The liquid in the hotter chamber is recovered from a downstream stage of an oil deodorizing process. Baffles are provided above the gap between the guide walls and the partition wall to aid in fluid circulation.
