Along the same lines, GW, have you seen the vapor assist a couple extract companies are doing?
They are using the vapor pressure from a warm tank of butane hooked up to the vapor port on an iced tank to push solvent and alleviate some stress on the pump and then later hooked to the top of the column to expedite the final dump. What are your thoughts on this technique?

Why do you recommend end cap reducers vs regular end caps like the ones you'd put on the bottom of an mkiii's 6x6 and weld a flush male pipe thread on it?

Concentric reducers are only really wanted for top down showering. For the simple fact that there isn't a crevice that solvent can have a hard time reaching during the injection.
And for the extra space on the larger ones..

I love this idea. Very smart.
Because it is available off the shelf without having it custom made.
It allows the top and bottom caps to accept 2" columns, and expand up to 4" with end cap reducers.
We wait and separate before heating the columns.
Haven't tried it, but it shows some brothers and sisters have been scheming, hee, hee, hee........
We are taking our design in a slightly different direction, and keeping the butane in the tank around 30F, so that it is still easy to pump.
We plan to use a counterflow heat exchanger, chilled with liquid N2 at the injection port, so that the columns themselves only see subzero butane.

Short chiller after the pump and another one, possibly longer, before the injection port? A longer coil before the tank so the tank is warmer than the chiller ahead so the tank is pushing to go to the chiller? Short guy being around 10' and longer one being somewhat past 20'? Or am I way off?

Dab,
A counterflow chiller is kinda like a tube inside a tube. A donut and the donut hole, so to speak. Coil it up to increase the contact length and run the solvent through the inside tube, LN2 through the outside tube. It's called counter flow because the LN2 flows the opposite direction of the solvent for max efficiency. They are a very efficient type of chiller overall.
Sounds like GW is planning to have the chiller right before the injection port on the column to minimize the length the chilled solvent has to travel as it can be a gel at low temps and strain pumps/take time.
Gray Wolf, do you think a vapor assist would still be beneficial to implement with the counterflow chiller setup to quicken recovery time of the column? It really looks like those guys are able to drain their columns at a good rate.

..i just killed a trooper of an appion and realize this is not the pump i want to be using ..i'm currently firing up a cps tr21 with an mt69 ..
..in my facility i have a huge compressor tank with a 6hp motor ..will this be sufficient to drive a haskel 59025 ..? the specs list a 10hp...
..thnx in advance for any thoughts

It will run the Haskel, just not at full speed. It is a fixed volume pump, so 24 scfm will run it at about 60% speed.

I just wanted to chime in on the previously mentioned technique of joining a vapor port from a warm tank to a vapor port of a -20f tank. It' been a game changer for me as I have no access to dry ice or liquid nitrogen.I'm bottom flooding room temp material with -20f butane and getting gorgeous light coloured oils from fairly gnarly outdoor. The only down size is needing multiple tanks to freeze if i want to do multiple runs in a day. (I still havent gotten a blast freezer yet)
Anywho, big thanks to this glorious community of info sharing. You guys are great.

so let me get this right ... you warm an LP5 and connect vapor to vapor to another LP5 which is at room temp. Than you use that second LP5's liquid line into the system? Than I'm assuming you'd put your gas back into the first tank? Hmm ... I'm really fighting the TR21, maybe this would help?

Im running the warm tanks vapor into a -20f tank to build enough pressure to push the subzero butane out of the frozen tank and into the extractor. The warm tank is also my recovery tank. When i said room temp I meant the material I'm extracting.

Jay,
Everything is setup the normal way, with the tank on DI. Then you bring in a second solvent tank on warm water so it has some vapor pressure. T the warm tank's vapor port an run a line to the cold tank's vapor port, inline with the pump so you can meter in pressure from the warm tank to assist pushing the cold liquid into the extractor. The other branch of the T off the warm tank's vapor port goes to the top of the column, inline with the injection manifold up there. Valve it such that when you are dumping the column, you can meter in the warm vapor to push the cold liquid out.
I haven't actually done it, just seen it setup. What do you think? Seems like it would apply to any size column.
