Hi all,

I have this idea in my head and i cant make up any calculation it'll
do when building this design.

I have an picture here
http://aycu27.webshots.com/image/27706/2003082782343486285_rs.jpg
[/IMG][/URL] cause it'll probably explain more then words only.
The idea is like plates in a reflux colom but then smaller exctually.
The smaller pipe will trap upward steam wich will be forced to
trickle down and so cool a bit wich will be sort of run again.
as the picture shows only 2 backwards pipes it could be more.(ore
less)
the backward pipe could be 2 till 5 inches log as the colom will get
higher offcourse. my hope is to get an volume of about 90% from the
exhaust pipe.

The concept is from the idea to safe up cooling water as were i am
dont have running water only a 30liter vezel and an circular pump.
Wich i need to let cool for a day to run my pot again.
Just to get an 80~85 volume.

Reflux is condensed vapours retutning to the column for further processing.  Your design has no means of condensing those vapours.  If the top section of your column was un-insulated, then you would get a 'small' amount of condensation via temperature loss to the surrounding atmosphere.  It would not be enough to make any appreciable difference to the purity of your product (the reason we employ reflux in the first place).  You need an overhead condenser to achieve useful reflux.

Slainte!

Perhaps it's me who is not totally understanding here, but it seems
that you are maybe confusing the idea of what a bubble plate does. If
this is so, then I would recommend that you read up on the principle a
little bit more.

From the looks of things, there is not going to be any place for
condensed vapour to come into contact with the rising steam, and hence
no reflux. This column will heat up just like a straight pipe and
should, if any, make only a very negligible difference.

And there is negligible condensed vapour. You NEED a reflux condenser
or a stream splitter of some sort, or bubble plates.

On the other hand, having the condensed vapour channel into the center
might help out with equilibrium over the copper scrubber pads? I am not
sure, you would have to compare to a traditional packed column. But why
would you put in the extra time and cost when you know the traditional
column works fine to pull off ethyl alcohol's near azeotrope?

>The smaller tube down the middle will work,but you need some cooling
on the pipe to get reflux.I built one that has a smaller pipe going
down the middle,but I wrapped some 1/4 inch copper around the smaller
pipe,and soldered the coil to the pipe.I run cooling water through it
to cause reflux.The one thing that I did to the bottom of the smaller
pipe is notched out the end with a hacksaw.I cut v shaped groves all
the way around it,cleaned up the edges,and bent all the teeth inward.
The pipe looked like the teeth on a holesaw,but bigger.With them all
curling in,the reflux will drip down the center of the packing.It has
2 seperate condencers.One for the column,for reflux,and one for the
condencer.It works.This is mounted on a 3 gallon presure cooker,and
is made with 1 1/2 inch,and 3/4 inch copper,and is only 15 inches
tall.It will run 85%.My friend has it,and runs it on the stovetop in
his apartment.

Ok,
so either it wont work unless i putt so many in this colom it wont fit
my sealing, ore i still need cooling coils to get the reflux needed.

So this design can be burnt at the staple.
And better turn the liebig condenser of the potstill up 30 degrees so
there will be more reflux in it the in this design.
And probably more volume from the exhaust.

Ok thanks for all the reply's

JD,

The column needs some sort of packing for reflux not
the condenser.

The column is where the reflux action is achieved.
The condenser is where the vapor is, well, condensed
back to liquid. Whatever purity goes over at the
opening on the condenser, will be your result. You
might want to look a little further into the process.

What you have, at this point, is a fancy looking pot
still.
Harry' reference library has some good stuff too,
but I can't find my link (no pun intended) right now.

hmmmm?))

If you want less feints while keeping the quality you can use reflux
detail in his corn whiskey book. The process requires careful
monitoring and adjustments but gives good results.
