Dear everyone,

 

Could someone tell me when we need a stripper instead of a distillation column?

 

Thank you in advance,

A stripper column does not have a condensor, or reflux, or rectifying trays. The column feed is on the top tray and the overhead vapor composition is resulting. It can only be used if the resulting bottoms product has a composition specification, but the overhead vapor does not have a composition specification.

 

A stripper column is normally used to remove light components from a liquid, by reboiling, or stripping with steam or another gas.

 

If not only the bottoms liquid but also the overhead vapor has a composition specification then a stripper column cannot be used and a proper distillation column has to be used.
