are a number of designs of reboilers. It is beyond the scope of
this set of introductory notes to delve into their design principles.
However, they can be regarded as heat-exchangers that are required
to transfer enough energy to bring the liquid at the bottom of
the column to boiling boint. The following are examples of typical
novel development in reboiler design is the self-cleaning shell-and-tube
heat exchangers by Klarex Technology for applications where
heat exchange surfaces are prone to fouling by the process fluid.
Particles are introduced into the process stream and these produce
a scouring action on the heat exchange surfaces. An example
is shown in the diagram on the left. [Click
