Why cool the reflux column?
- Perhaps some of you running reflux columns can answer this: Why pass
the condenser cooling water *through* the column? It seems that this
would mess up the reflux "plate" arrangement. If you wanted to 'cap'
the column to allow for total reflux, could you not just have a coil
or some other separately controlled cooling device at the top of the
column, just below the vapor take-off? "Preheating" the cooling
water seems like a bad idea, and I can't see why the water should
pass through the *bottom* of the column, at least...

the idea started.
The best plan is to have the reflux enter the top of the column at
boiling. Cooling anywhere other than in the condenser, or cooling the
reflux below boiling, is a) a waste of energy, and/or b) detrimental
to output quality.
