I have read on this site others doing stripping runs can you please explain
what the benefits are and the procedure and do you think it is worth while.
cheers Ken Mc
a) Rapidly boiling the wash and condensing everything that is vaporized,
without bothering to separate the heads and tails, is an easy way of
reducing the volume of liquid you will subsequently process with care,
saving a lot of time overall
b) The reduced volume of liquid you get from a stripping run is clear of all
solids, salts and dissolved gases.
c) The liquid you get has a very much higher concentration of volatiles,
enabling far better separation in the subsequent rectification run as you
start out in the middle of the equilibrium chart (the one that plots the
concentration of volatiles in the vapor against their concentration in the
liquid the vapor came from ... the one that looks like a fat cigar leaning
at 45 degrees)
In essence, it is much easier to clean a muddy kid after a football game if
you first give the brat a quick hose-down to get rid of most of the mud, and
then then shove him in a clean, hot bath with a cake of soap with
instructions to wash behind his ears, than it is to try and do it all in a
bath full of muddy water. Whiskey distillers, who have to tackle the
difficult job of dealing with a mash full of solids, first concentrate on
separating the low wines from the mash in a big still, where the only
problem is to prevent burning, and then move on to a smaller still where
they concentrate on getting the right cut from the clean low wines.
Experience has taught them that this is a very effective and efficient
procedure that results in a much better product than if they tried to do the
whole job in one go. It is definitely well worthwhile.
