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.
Claims18
A distillation column comprising:
- at least one heat exchanger,
- wherein a bottom portion of the at least one heat exchanger is positioned within a bottom sump of said distillation column,
- wherein said heat exchanger comprises a central vapor inlet pipe and an outer shell forming an annulus shaped space between said central vapor inlet pipe and an inner surface of said outer shell, and
- wherein said heat exchanger contains a series of internal concentric ring baffles for directing flow of vapor inside said outer shell.
