Speaking of burping...
I know that when you tap cap's to fill a storage tank some atmosphere is pulled in and that there is some propane in the canned butane as well.
So how far down would you have to chill a storage tank so that the only gas in the tank was atmospheric gases and propane?
Would -20 degrees celsius -2 farenhiet be cold enough?

Yes. Propane boils at -42C, and Isobutane at -11.7C. The N-Butane boils at -.5C.
Depending on operating conditions, the Mk IIIA may hit 50 psi, and with multiple screw ups has hit 80 psi, but it is a 150 pound system, so it isn't of concern.
We occasionally see leaks at the Triclamp connections if we don't keep the seals and o-ring grove clean. I have noticed that the double hinged clamps work better than the single ones, so have started using them where available.

What was strange was that there wasnt any leaks for the first 3 pulls, then it started to spurt i shut the in line dumped the column and it stopped and started to recover butane.
Did a run after with no problems.

probably due to more pressure. i had my top tri clamp leak on me once and it wasn't until the third cycle that it started to leak.
the other times i've had a leak, it has been at the return tube ball valve and the 1" main ball valve. it always happened when i just cracked the valves enough to dump, but slowly. i took them apart, cleaned them, and no problems since.
i freeze my tank when not in use and use to burp, but i actually had more problems until pressure was built back up in the system. now i don't worry about purging propane or pressure anymore. but then again, most of the time we have our tank in dry ice.
i do highly recommend running a filter before the appion in case of a screw up where you dump too much butane into the system. a site glass before the filter that tells you what the water content is also helpful for a variety of reasons.
we developed a small leak in our g5 after about a month and a half of use. i tend to wear ear plugs when around it, but discovered it when it was off. well, i heard it.
i also highly recommend this: http://www.amazon.com/gp/product/B0017Z5DZO/ref=oh_details_o08_s00_i00?ie=UTF8&psc=1
it is cheap but works amazingly well. interestingly, cleaning the unit with denatured alcohol or making absolutes is quick to set it off compared to opening the terp up after a cold extraction.

So with a pressure gauge attached to a tank at -20C if the pressure was not zero that would be evidence of gas other than butane and the tank could be bleed to zero, while of course observing standard safety precautions.
Interesting thought, cooling the tank to -20C it should be possible to recover the propane and atmospheric gases to another tank and then chill the second tank to less than -42C to separate the at atmospheric gases from the propane.
Any off the cuff idea about how much propane is typically in the lucienne butane?

Was there any resin or plant matter on your oring?
Did you pull a full vacuum and let it sit for awhile @-29.5 before your run to make sure there were no leaks?

No, it just was too full.
As soon as I shut Valve #4 (butane in) and dumped the column it stopped right away and began recovery. Luckily I didn't mess up my G5!
Now I am much more careful about my flood time and packing the tube

They don't break it down, by percentage on the MSDS, but typically propane runs around 11/27%.
We pull the whole system down to -29" Hg before valving off the dump valve and the vent valve, prior to changing columns.
After the new column is in place, we open both valves and pull to -29" Hg again, before proceeding with a flood cycle.

GW as always your light shines bright in the darkness. I was surprised just how much propane and atmospheric gas I had in my tank. Did a L O N G burp and then a run. Recovery time dropped by about 35%.
Really?
Well if thats the case it makes alot more sense that there would be empty cans to me.
For a product of this nature 11-27% is a HUGE difference imo, kinda shows how strictly regulated the industry is, or isnt for that matter...
"Hey! How much propane we need in these cans boss?"
"Just fill em with the usual, somewhere between 1/10th and 1/3rd"
Perhaps we can suggest a canned butane episode of "How its Made"??
I wonder if the variation in amounts of propane has to do with gasses settling (not sure if thats the proper term) in the machine before they fill the can.
Also the variation in gases might have something to do with that "mystery oil"...lots of possibilities....
The variation that I quoted was by brand. They keep the same mix within brands.
Typically they are mixed with a proportioner, which blends the gases from individual sources, so there is no settling and they typically wouldn't settle out sitting around, as they are a mixture, not a suspension.

Ok gotcha, simple misinterpretation. Penzen was asking about lucienne specifically so I thought that's the brand you were referring to. Thanks for clearing things up as that makes much more sense.
Since they typically dont settle is it just a conditioned habit of mine to want to shake each can before using it?
GW just want to take a quick moment and let ya know I really appreciate all that you do. I have a patient with stagev cancer in his bones and he has been loving the extracts in the various forms I have given him. Nothing is giving him this level of relief.

this thread is awesome! i hope to be at you and gw level in the near future, keep making those bomb extracts man!
I think this alarm would be of more use for my application.

If I were to use the one posted it would be going off every time I vac down my column at the end of a run. That one may be more practical for indoor use, eh Durden?
The buna gaskets expand and contract with the temp changes, as well as are susceptible to leaking if not clean. I tighten my clamps until the gasket just begins to bulge out of the clamp. Ill try and get a snap of it.
ICdog Ill also get you a loading pic
Nice first run Veg, hope you come back and join us.
A crystal update .....
