Revamping a Distillation column

Revamping a Distillation column

Revamping a Distillation column

I would like to know what are the most important parameters when a distillation column needs a revamp and why?

RE: Revamping a Distillation column

Wow! what a simple question !
I will try to answer the question's first part, in repsect to capacity enhancement.
you need to get vapor+liquid flows on each trays, downcomer backup, flooding margin, velocity under donwcomer, increased pressure drop and adequate margins for foaming tendencies.What kind of trays you have in column, if antispin valve trays are there.... This is besides the reboiler and condenser duties.

You can best refer to Distillation "Design" and "operation" by Henri Kister.

why part: refer to these books.
