Wow ethos still exists and is still putting pentair fibreglass pressure vessels on their skids?
Thatās a terrifying place to cut corners. ASME stamped stainless vessels are cheap.

Acids and bases have two different faces,
Two different personalities,
And you gotta find out what theyāre all about,
If you want to learn chemistry.
Now the first thing you gotta get straight in your head,
Acids turn blue litmus paper red.
They react with metals with awesome power,
They neutralize bases and taste very sour.
Bases are different from acids, itās true,
Bases turn red litmus paper blue.
They neutralize acids, feel slippery on skin
They taste sorta bitter, and are called alkaline.
Acids and bases have two different faces,
Two different personalities,
And you gotta find out what theyāre all about,

I donāt see why running high pressure Etho would be any different or more dangerous than water in the pentair vessels. Some of their models are rated for up to 1200 PSI.

Well actually I was thinking more mineral acid vs orgainic acid for acidification. The latter buffers out at about pH 3.
Might want to think about that submarine accidents reason !

Curious chemistry indeed.
Shoulda got a peer review on that submarine 
Pretty sure they deliberately ignored their peers on that oneā¦
Peer review is one of the primary reasons I hang around this placeā¦

My degree might be in mechanical engineering, not chemical, but I sure can.
Especiallty when pentair specifically said they wonāt guarantee compatibility with any solvents.
I spent a good amount of time trying to get info from Ethos on the subject, I believe their final answer was āwe soaked housings in solvent for a while and didnāt observe any problems so weāre fineā with it. The thread is around here somewhere.
Let me put it this way: if I were asked to sign off on a peer review of these skids, under no circumstances would I put my personal liability and reputation on the line and stamp them.
They might be fine for a year. Or five. Or twenty. They might not.
I KNOW that the solvents in question donāt attack stainless in the long term. I donāt know a goddamn thing about the compatibility of the epoxies and compounds used by pentair. And pentair knows enough to say they wonāt say.
Equivalent stainless housings with stamps are well under $10k a piece even if youāre shite at sourcing equipment. With how much ethos charges for their skids, they could easily eat that cost.
Not my facility, not my solvent pipe bomb. Everyone takes their own risks. To me, that one falls way too high up on the severity end of the risk matrix to take the chance.
EDIT to continue my safety rant:
Are the housings fine in ethanol? Maybe.
Terpenes are solvents. A lot of people are using heptane-denatured ethanol.
Are they fine with heptane or the absolute shit mix of solvents and unknowns we throw at them? At unknown pressures and temperatures and duty cycles?
Given a timeline of 10+ years, Iād be willing to put a shiny nickel down in the No column.
Will ethos even exist to sue at that time if these are still in use and start exploding? The last half decade Iāve spent in this industry suggests that thatās more than likely a no.
Engineers in Canada wear an iron ring on the pinky of our working hand, which is supposed to remind us that the decisions we make can affect the lives of many many people. Not a lot of professions get to kill people wholesale when they fuck up. Doctors and most other professions do it one at a time. People who drive big trucks could get dozens. Engineers get to count by the hundreds or thousands.
I sleep just fine knowing that everything that Iāve designed and implemented has substantial safety factors and protocols in place. I personally run the equipment I have designed and run, and people that I care deeply about do the same.
We had a major piece of equipment go non-linear a couple of weeks ago. If we didnāt have comprehensive grounding and bonding and inserting protocols and systems in place, you likely would have read about us in the news. But you didnāt. At least one piece of the chain in the protocols protecting that system is āexcessiveā or over and above what the code requirement is.
There are corners I absolutely cut if they donāt compromise the safety of the system. Or if the risk and severity is very low, especially if Iām the only one who might be impacted.
I absolutely would never run a fibreglass housing on a membrane skid. The cost savings are simply not worth it.
But what do I know, Iām just some random guy on the internet.

Looking great man. Applaud you for speaking about it. I feel like there are people that would literally kill to keep this secret, especially when the industry wide ramifications this tech brings with it come to fruition. So many lost dollars in unnecessary equipment when it can be done so easily.

Soon there will be one, hopefully in about a month. Itās being assembled now. Definitely not the biggest one, weāre starting smaller until itās fully proven. Something like 200lbs a shift, but itāll be the first in the cannabis space. They have a few units in other industries already. Looking forward to solventless disty.

No nitrogen in THCa so it can only form tetrahydrocannabinates with basesā¦ magic acid??? Are you guys talking about an acidic aqueous solution that solubilizes acidic cannabinoids? I am not a chemist! I donāt know whatās going on!!!

Well you can look up water extraction chemistry by doing a patent search. Think of what you are thinking about backwards. When the cannabinoate is solubilized in water you have to acidify it to make it insoluble in water turning it back to a cannabinoic acid (r-cooh) which is non polar soluble. When this occurs the cannabinoic acid precipitates .
When working with CBDA this precipitate is not always white and pretty. So the question is: is there a preferred method to precipitate as a R-COOH or does one have a special āmagicā method that yields a carboxylate salt that precipitatesā¦such as R-COO- (X+) and makes a nice pretty white salt. Or is there a special way to make an nice white R-COOH? As Lincoln pointed outā¦there are proprietary methods worked out that are not being discussedā¦because there has been an enormous amount of work put into these subjects.
As mentioned above there are a number of patents concerning such proceduresā¦at least one covering the R-COO-(X+) salts, ones covering the R-COOH forms and at least one other covering the Phenolate salts of the ring hydroxyl(s). The greenies are on the grow.
Then the plant material and Nature have their secrets as well. Butane works but no theory post goes over a number of known unknowns. The āwater scenarioā discussed above is actually much easier to understand.
Iām laughing at my own ignorance. ā¦so donāt feel left out.

Itās a batch process, or continuous?
Is it able to process fresh frozen material?
Have you sampled the end products, how are the terps??!
Any hints with the costs?
