Re: Tri clamps from China?

I have bought them too. They're fine. In all likelihood the ones you bought locally came from China too. +1 if you REALLY want to pay 5 times the price you can get the original european from from alpha laval. One downside with the Chinese ones I get though, the ferrules are 304 but the clamps are o...

guys, this is a construction thread, isnt there a SPP all purpose, brainstorming, Q&A thread somewhere else ? If not can you create one DAD ? We already have 3 pages of information that does not belong here.

Re: Structured Packing Density

But it is useful to have the density information for all types of packing. Can you give some density numbers for your SPP packing for comparison? about 1.6 kg/Liter. That's the rather compressed density after tapping the column on the floor. It can be less dense if just poured. SS is about 7.8 g/cm...

Re: Another continuous stripper

TL;DR
- wash is not enough to condense all the output, you need a water condenser on the product output
-1% on the spent wash is too much, lengthen the tower or get some SPP

the u bend will have the temp of boiling wash ideally, which is hotter than pure ethanol, the bottom must be maintained at the boiling point of water.

Re: ideas for breaking down an azeotrope

it's probably much more soluble in water than etoh if used as drying agent. Moreover, if we wanted to break the azeo we'd try to bring the boiling points of etoh and water further apart not closer to each other, wouldnt we ? On top of that the use of the salt would only work for one single evaporati...

I completely failed getting 100 % abv under vacuum, in short the trouble with vacuum is that you are trying to make heat and mass transfer between liquid and .... almost nothing.

Re: Boka Needle Valve

you must put it above the liebig because 1) if you put it below then the liebig will likely keep filling up when you close the valve preventing you from increasing reflux as intended 2) after it has more or less filled up you may want to reopen the valve and you will get a temporary high flow becaus...
