Column or tower?
Column or tower?
(OP)
I've heard the terms tower and column used interchangeably through out my career. What, if any, difference would there be between a tower and a column?

RE: Column or tower?
I've seen these words indistinctly applied to mean vertical, cylindrical vessels used in chemical and petroleum processing, for example, to increase the degree of separation of mixtures by distillation or extraction, with mass and heat transfer processes, and sometimes chemical reactions, taking place.
However, it is not always so, for instance: cooling towers aren't usually cylindrical, and vacuum towers may have three different cylindrical sections.
Any comment ?

But this is not a hard and fast rule, and Perry seems to use column in preference to tower. I am in South Africa and both terms are used here, but in the industries where I have worked column has been the more common terminology.

While it does not answer the specific question (above) it does provide some background to some vessel terminology along with the design guidlines relating to the location of nozzles, external piping, pipe supports, ladders and platforms.

James O. Pennock articles are exemplary (see, for example: http://www.pipingdesigners.com/Training.htm), and very instructive. Pennpiper's referee posting merits a star.
