Right… the Whole Foods thing threw me off big. They sell a few things that might be used, DE or charcoal or bentonite etc… never ashamed to admit when I don’t know something and will throw spaghetti at the wall endlessly until the pain stops lol

Personally I knew all of this all along, I was just waiting for you dummies to figure it out.

Spill the beans. I love Whole Foods, it gives me a reason to leave the hood. Which absorbents are you using? I love extractor riddles.
In case this non-IUPAC name is giving anyone else fits… this is diethanolamine (DEA), correct?

Just to be clear, if we run DE and a mol-sieve, we likely won’t experience this?
I spoke to a dry ice producer here in Georgia, and he mentioned as well that refineries are shutting down. Many of them have been cutting corners and experiencing shortages are no longer able to produce. He’s having to supplement for multiple states. Apparently liquid nitrogen is triple what it costed last year. Don’t know if there is a correlation.

I guess having clean solvent is important after all…

Hey @Kingofthekush420, where are you in the development of butane membranes? Check out the second paragraph. If I were you I’d be checking whether my membranes could remove DEA from the process stream….
This one highlights the use of Rectisol (methanol) for removal of sour gas (H2S)
Who wants to take a guess as to what the big boys are using for amine removal in these large supply chains?
What do you do when you have diamonds that bleed?
Why, I’ll grab me a column and fill it with beads!

We need T-shirts now. It turns out the DEA is messing with us all over the place!

…an adsorbent bed is going to have a fraction of effectiveness compared to a wet scrubber, and ultimately may not solve the issue entirely.
The real issue here is nobody in the cannabis space has created a wet scrubber until @ricky9900 crazy ass rigged one up.
This is not a “go buy some shit at whole foods” type fix
Wet scrubbers are difficult to operate and optimize, kind of the same way fractional distillation towers are difficult to operate and optimize.
Edit–Also, yeah you don’t get any contaminants in the gas stream of you GC-FID because you buy analytical grade gas and filter through a triple trap it at a rate of 0.2mL/min. This is not the same as 100s of lbs of butane a day.
Edit 2: Also, and i’m sorry to do this, but if you’re going to come talk shit on every post here’s some help on spelling–it doesn’t help your arguement when you misspell the important words.
“adsorbant” is spelled adsorbent
“filteration” is spelled filtration
“contaminates” is spelled contaminants

Thanks for the write up @Dukejohnson. I know I’ve been quiet around here—this is the culmination of a lot of new relationships, coordination, and chemists way smarter than I am. We’re still plugging away on some additional improvements and methods to roll a solution into our processing flow. More pieces to put in place before I put more info out but I wanted to drop a line to thank everyone here that participated in helping us in any aspect of figuring this out—an admirable collective effort as far as I’m concerned. An even bigger thank you to Rami, who doesn’t have a presence here himself, but has been an integral part of our team since the very beginning—we couldn’t do anything we do without him. More to come, hopefully sooner rather than later. Cheers y’all

So I should stop scrubbing my collection out with soap and water?

We’re in the process of releasing some new skids as we speak
This one does 3 gpm to start solvent recovery and costs 45 to 50k
It will be available in ethanol or hydrocarbon membranes
DEA is too small to be rejected by tangential flow filtration membranes, doesn’t mean you can’t reject it with the correct ceramic with the correct layers. Methanol can be rejected from ethanol with a specific membrane so rejecting methanol from a hydrocarbon gas stream wouldn’t be hard
@joeltangent is going to be introducing himself to the forum in the next couple days

Sorry I drove 1200 miles yesterday, wasn’t really in the best shape last night 
Grammer isn’t my 1st priority, and I am also quite dyslexic.

I caught two flights, commissioned a new lab yesterday and made 10 pounds of hash and wrote this write up in the airport. My spelling and grammar is not perfect by any means 
Yes @anon64373531 thank you so much my phone really wants to autocorrect diethanolamine. Thanks for the call out!

Just a friendly tidbit, we are both standard know-it-alls who talk too much shit. 
Spelling correctly helps.

did solvent direct have something to do with this discovery?
