So "Guest" what do your "mates" call you?

I guess I thought you were the one who claimed copper was bad and plastic (nowadays) is fine etc, etc, etc...
Recently it seems its not you (if it is you) because of the attempt to be productive in the forum, while, shall I say, still abrasive in your replies.

Why not registered or at least sign the posts with a name?
How do we know what weight to give the advice if we don’t know who it comes from?
Do we call you "take care" :roll: ?

resevoir for what reason?

Postby guest » Sat Dec 03, 2005 8:47 pm

Hi, I'm not building this Bokakob design right now, but I wonder why you would want a resevoir of liquid over your offtake valve? I thought it would be best to have as small as a resevoir as possible. Bear with me... If you do have a resevoir, it will contain higher percentages of the higher order alcohols that are starting to boil when you are running out of ethanol in the column. I figure it's best to just hold as little liquid over the valve as possible, so the vapor that's currently being produced (and hence falling onto the valve) is the majority of what's coming out of the valve. Hope this makes sense to you guys.

I don't think it makes much of a difference either way. If you are running a multiple distillation potstill, a NS offset, Bokokob's EL, tubes through the column, etc. You turn off the distillate take off once you recognize components coming over which you no longer want.

Guest it's not really a reservoir. I got a sight glass there to see if things are backing up. I set the output to a slow draw and then udjust the reflux accordingly. If I see the level climbing much above the reflux valve in the sight glass I open it a little more.

LOL... yeah those are a couple pictures from last year. Ski touring is another passion of mine. I was pretty surprised to see em there on the distillers forum...oh well anyone who was interested probably saw the still pics before.
Cheers!

This is very interesting to me and also above my head, but the pictures would be nice to see, I'm just seeing pictures of 3 dudes on a snow covered mountain, no still in sight!!!!!!!!!

No not a joke there used to be still pics there. I uploaded a half dozen ski pic to that server a couple weeks ago. Those couple must have been assigned the same image tag as the still pics... if I get some time later in the week, I will try to straighten them out.
