Per your guidance, where do you recommend operators dispose of the toxic mystery oil they are distilling from their systems containing benzene known to the state of california to cause cancer and reproductive harm?

Do you provide recommendations on the appropriate PPE for handling toxic mystery oil? Do you recommend EPA compliant hazardous waste per the Federal Regulations for Specific Wastes requirements?

To be fair, everything causes cancer in California

We’ve had many ppl come in and tell us you specifically told them they didn’t need to distill your gas.

“We do however advertise significant savings of the time, money and risks of distilling “mystery” oil out of “clean” gas when these dangerous exposures and wastes can be prevented by decontaminating cylinders before refilling.”

You’re literally telling ppl you can save money by buying your gas, not having to distill it, because your cylinders are clean. That’s highly misleading in telling ppl they save time and money and don’t have to distill your gas because it has no mystery oils when in reality, it still has contaminants.

And I tell my customers the truth, which they appreciate. We don’t add a bunch of marketing fluff to sell gas.

Are you on the same page that Cortland sells industrial gas? If diversified stream was affected, SD and us would be seeing the same issues from our current base

How much operational time and money you need to spend on safely distilling and disposing of mystery oil depends on the supplier you buy it from.

Show us your COA’s changminXD.

what is the other .200 in the gas??

Why not get a COA showing the heavier hydrocarbons and showing .00000 on those espeically the C6 compound we are talking about; benzene?

And @Cannagas would have seen it pop up, also my coa’s would have failed for it

Not at all. I’m rather familiar with the process as I live a few minutes from Cortland’s facilities. I’ve been on board since around September of last year so I can’t speak for before that.

As to Diversified, that’s why I said it’s somewhere in the stream, because (thankfully) not all of its distributors are being impacted.

Exactly. Diversified literally owns the gas market in the USA for instrument grade. No matter who you go to for instrument grade, it is supplied by them. They’re a multi billion dollar public company and if there was a contamination issue from them, they’d catch it before it left their facility to their distribution chain.

I wonder if the wax suppliers on candle making forums trash each other like how we see all the suppliers trash each other here :thinking:

what if this was just a simple error like a lot of tanks got filled without cleaning… we are all human… we all make mistakes. seems like any company could have simply not cleaned some tanks and had a build up of benzene in the tanks

This is exactly why I mentioned spot testing from end use cylinders as a final control. Along with testing through the entire supply chain, it should help eliminate human errors before product leaves the facility. You’re right though, shit happens, we (gas suppliers) just need to be committed to minimizing it as much as possible since it clearly can have widespread, harmful effects when we don’t.

I spoke to Rex and Steven at Cortland a few months back about their gas and they mentioned distilling their own gas, which made me very curious. After doing some more research into the entire LPG instrument grade industry for butane/propane, diversified came up as the biggest one that is supplying all of us through a bunch of distributors/resellers. Cortland is not tapped into that same supply chain as far as I’m aware. I could see cross contamination of the actual tanks from them and other gas suppliers being the issue because gas companies usually take in cylinders from any one as long as it’s a similar valve and cylinder type.

Great point Killa. With the potential for dangerous petrochemical waste accumulations inside LPG cylinders, why doesn’t everyone show us how, where, when and how often they clean their cylinders. Provide documentation with signed certifications and DOT serial numbers would be a great idea.

Anyone?

arent all you guys using diversified all getting your tanks cleaned every fill. thats what i gather from speaking to most of the people that send their tanks to a central fill station.

Ain’t no benzene in the gas if it’s good gas. Let it accumulate for a decade, still 0 benzene.

Absolutely true that we are not part of the Diversified chain and that they, by far and away, supply the majority of the extraction has in the country. However that doesn’t mean that we provide industrial gas because we are not part of the largest supply chain.

I think there may be a terminology issue, Cortland doesn’t distill it’s own gas, it cleans the gas it takes in to further purify it by removing paraffins/olefins/sulphurs. Either way, glad you’re in touch with Stephen and Rex—I’m sure they told you the same thing, but if you’d ever like to take a trip and check out our facilities/process we’d be happy to show you around. Also always happy to hear constructive criticism if you spot something we could be doing better.
