vacuum column distillation with stripping steam
(OP)
hi all
i want to ask about the stripping steam in vacuum column
what will be the problem if the bottom level of the column increased and the inlet steam will go under the level?
thanks

RE: vacuum column distillation with stripping steam
1)agitation in stripping section,
2)very high expansion ratios exist in vacuum if somewhat wet/ saturated stripping steam is employed,even accidentally!

High turbulence, possible entrainment, difficult liquid level control, false liquid level signal, flooding, etc.
One suggestion: read chapter 13.2 (Liquid level in columns) in the book by Henry Z. Kister: Distillation -Operation- McGraw-Hill

i want to ask you Mr.25362 about the book is it available as e-book? and thanks again
RE: vacuum column distillation with stripping steam
I'm afraid not yet. It is offered for sale via the Internet.

Same is the case with authors; if such a thing is somehow missed or inaccurately reffered/ quoted!

I have not come across any such high temperature limit; other learned forum colleagues may enlighten on the subject.
However I've seen temperature(s) 645 +/- 20 degrees F for 35 psig stripping stream coming out after heat recovery from Fired Heater flue gases stream; while at previous employer's refining complex.
Hope this helps.
