Abstract

See full text

The invention is a reboiler-condenser which increases the efficiency of heat transfer between boiling and condensing fluids, such as oxygen and nitrogen in air separation or similar cryogenic applications. The exchanger is built up from individual plates, the opposite sides of which have enhanced condensing and boiling surfaces. The condensing channels are inclined slightly downward so that condensate can be removed at many elevations in the exchanger.
