  • Patent number: 12233363
    Abstract: Heat exchangers (also referred to as exchangers herein) are provided that fit within a bottom sump of a distillation column. These heat exchangers may be at least partially submerged in the bottoms fluid of the distillation column so that the exterior surface of the heat exchanger can contribute to the total area of the heat exchanger. The internal configuration of the exchanger allows for annular coaxial flow of the hot fluid (condensing vapor stream) and eliminates the need for top and bottom channel heads.
    Type: Grant
