We have, it helped a little but still having the issues. Using more media seems to help also for some reason. Still trying to figure out the exact culprit though

More media helps? Hmmm thatās weird
Are the areas in effect suffered from wild fires near by like one guy mentioned?
Iām just wondering bc w the Media helping it seems odd to meā¦whatās medias help it might point somewhere like clays like heavy metalsā¦other like mold spores and pesticides?

Why would none of these things show on tests then? We have seen the opposite issue where more media makes the chalking issue and fast crashing issue worse.

Thatās what I was thinking bc it does that naturally pulling everything but mainly thca left when u over powders
The digging it out u get chalky sugar
Iām going to temp cycling for making diamondsā¦I discovered it 2 years ago and documented here but I didnāt know what istumbled upon
This was after hr they were growing fast
To much tane so u keep doing it till it low enough not to melt the diamonds they just keep getting bigger and nugget up
And seeing ppls temp cycling jars and pans I know we own to something to bad I didnāt keep on experimenting 2yrs ago I knew I was on to something I remember talking to @cryo13 and @Killa12345 about(doubt heāll remember with all the disty consumed he drinks it like I do honey!)
So is the answer to switch expensive pharma grade gas?

Propylene peak appears between propane and isobutane. Weāve never seen a peak for propylene in C3 or C4ās.
Whose we? You sell gas out of your garage, and have told us that
We know itās testing positive for propylene now. What weāre test results on propylene during the same time as the results you showed above for neo pentane

Hmmm.
Even 10 ppm ought to show a bump on the GC report.
Iāll check with the lab come Monday and post what I learn.

Thatās strange since this is the same gas though, right? I mean I get that thereās an extra party in between, but Cannagas is Diversified > GI > Cannagas and QEG is Diversified > QEG.
@GasGuy-QEG / @n-beardtane, are the new fractionation towers online at Ironhorse yet? Iāve noticed theyāre situated adjacent to ExxonMobilās polyethylene refinery which, I would assume, is a large consumer of propylene. Given all the close ties between the companies, proximity, and railyard location, maybe the new plant has become a source of contamination? From what Iāve seen that plant came online (though potentially not at full capacity) in December 2020/January 2021. To me it makes sense that the products wouldnāt have worked their way into our market until early summer when these issues started popping up. Iām not insinuating that propylene is or isnāt the culprit, but if itās there and shouldnāt be there, maybe thatās a reasonable explanation.
As to neopentane, it always has and always will be in nBut. As @GasGuy-QEG has quibbled with me about before, certain ASTM standards donāt even resolve it from nBut. So if youāve seen a COA that doesnāt list neo, you can safely assume itās rolled into the nBut peak but still present.
Jim, itāll be interesting to see the propylene numbers from 2019-2020 when Diversifiedās only supply was out of Jolliet. If the Ironhorse location isnāt yet operational to the point itās putting products into this market, then I find it strange that two top tier Diversified distributors (GI & QEG) wouldnāt have identical COAās.
My 2 pennies for now, Iāve gotta go mow a couple acres

Hey Adam, HNY and hope all is well.
Not sure if the Diversified expansion is in operation yet. Our gas comes from their Illinois plant because theyāre only a couple hundred miles away.

Donāt know if any of this really helps point to the source of the problem, but I share it because inquiring minds might find it interesting.
The Cannagas analysis above is in the same format as the N-butane product certification on available from GI website. Notice that the table showing the results isnāt centered on the sheet (ok, thatās a little picky).

Couple significant differences: the GI document does not list propylene as a contaminate and the neopentane contaminate in the Canna document exceeds the GI tolerance.
@dr_terpene Cannagas has 2 different fill plants, one in MA and One in Cali. Do you know which of these facilities provided the analysis you posted?
Here are PDFās showing the order hydrocarbons present themselves in GC-FID testing. Two sources, one referencing more hydrocarbons than the other. The exact time each presents will vary slightly from one sample to another because of temperature, the column being used, ambient pressure and, for all we know, butterflies flapping their wings in Singapore, but the order of appearance is always consistent.

My laptop allowed me access to a recent GC report of the contents of the gas in our bulk butane tank. Propylene, if present, peaks after propane. No peak.

I suspect that itās there below 10ppm. From what Iāve been told, we will see problems arise even at the ppb level.
You say your machine will see a 10ppm bump on the gc. What about lower?
Seems to me, your able to see ppb. So weāre you just not testing for propylene then?
If your data is true then propylene seems to be our culprit. Especially if itās truly not there before and is there now.

actually no.
the elution order can (will) vary based upon the specific column (chemistry) used.
if using the same method (which specifies the column chemistry, temp(s), times, carrier gas pressureā¦etc), then elution order should absolutely remain the same, and elution times should be close.
variations in column length (one trims the column to deal with various issues) or carrier gas pressure will absolutely effect elution time without effecting elution order. in some cases the elution order can be changed simply by changing the temperature profile used (which == a new method).

The neo numbers I shared were %ages. .1041 = 1041 ppm. 1 ppm = 1000 PPB, there are very few if anyone in the industry with the equipment and standards to qualify let alone quantify < 1 PPM of propylene.
@FicklePickle You know a lot more about the extraction process than I do.
I donāt really expect the gas guys to help solve this.
āHey guys, hereās what you should sue us over.ā
Not likelyā¦

None of the companies in the supply line of this potentially defective butane have addressed the issue. Iāve invested time, effort and insight in hopes of isolating the cause and source of the problem. Wasnāt expecting a round of applause for my efforts, but I sure didnāt expect to have my integrity called into question.
