using a common condenser. That's the same thing as using a joining
manifold, and that's the purpose of same (equalization, or balance).
However (always a 'however', ain't there) you need to figure out how
you will return reflux EQUALLY to the columns. Reflux is necessary if
you're using packed columns, or you won't get good separation. It's a
two-way action. Said reflux needs to be equally distributed to the
columns or there'll be variation in each column's separation and
purity. Hence your collected product purity will suffer.
Of course, if you're just using multiple outlets to a condenser in a
potstill setup, then reflux balancing is not an issue.
