How long of a condenser would you recommend?

22

Currently looking at glacier tanks. 19 3/8” tubes in a 3x24.

I’m also curious about mounting it at an angle as I’m restricted on height

Like a 3-4"x18-24"

Have you tried Haskel? Pressure should be no problem, should be able to find something compatible in the DSF series. I know they offer full atex certs and they’re pretty inexpensive

I have a MVP liquid transfer pump for sale in normal

Downsize and split it between two evap and two condensing columns.

Not using an evap coil in this case. Just trying to use the tube in shell for condensing the butane vapor.

You’d suggest splitting it up though?

I upgraded to1/2" recovery and a sous vide, no coil, for 1 and 2lb runs, amazingly quick, like 10 -15 minutes, i can dial it up a bit
I will collect data on my next runs

Beautiful

Id recommend doing the heat transfer equations, or finding someone who can, so that you purchase the right setup the first time. That being said, if you wind up in a situation where the ideal column length exceeds your ceiling height, i would run 2 columns instead of angling. If you angle it, id worry that liquid would pool to one side and flow through too rapidly.

I have a 200lb honey pot.
I’ve considered throw a spray ball and use a mvp liquid to circulate as a ffe.
Any folks done this?

Anyone using a Hydra-Cell for membrane filtration?

The one Im looking at is rated for use with the 5w30 oil, but I see they have a “Food contact” oil option. Is this a concern, or am I correct in thinking that there is no oil contact possible with the pump type?

That is the one to use, just make sure it has rated seals

I’ve used hydracell and oil is not supposed to bleed through under normal use. CAT pumps on the other hand can’t be used for a food grade application as they allow some oil in the fluid stream by design.

Thanks guys.

My next googling and questioning is about proper/adequate flow rates.

Is a 1gpm feed rate a usable rate with 1812 sized membranes. I gotta learn more about cross-flow velocity and such I think.

I would consider 3-4 gpm more adequate

I dont mind if the process takes longer with a lower flow pump as long as the overall results are the same, which Im not sure is the case.

I remember someone mentioning PLC to enhance control. Hydra-cell offers metering pumps w/control freak system control. The trade off is a lower flow speed for the model in my price range. Its rated at 25gal per hour.
I have to find out if that will still pair well with 1812 sized membranes!

38

Different crossflow will completely change the way it performs and too low of crossflow will make the membrane clog very rapidly. Those metering pumps are way overkill. If you want hydracell get the d04. That will be pretty adequate for a 1812. Or get the d10 and have some room to grow

I can get either a p100 metering or a seamless F20 for the same price, others are currently out of my price range.

What price is a p100? If it’s cheaper than a d04 then I’m shocked.
