Re: multiple columns?
- multiple reflux columns will work. That is a excellant way to gain
more productivity from the same heat energy input. However, unless
you can figure out a way to divide the reflux flow to go back down
the individual columns, you will need to build a reflux condenser for
each column. Unless the columns are experiencing reflux, they wont
be giving you the product purity that you are expecting. You also
should build the columns as long as possible. 36 or 39 inches of
packed column section is the usual reccomended starting point.

multiple columns will get you a greater throughput, but it won't help
with purity. They're really no different to say just having a fatter
column. For purity, you need enough physical distance between the
low purity and high purity ends of the column. Its the height of
packing up the column which does the trick, not just the volume of
Its an interesting point though if you're talking more about a pot
still than a reflux column. If you were to put multiple vertical
pipes off a pot still (coming together at the top for a common lyne
arm & condenser), you'd be increasing the surface area generating the
internal reflux, and hence you'd probably get a higher purity /
lighter flavoured product, for little extra bother.
