Benzene in butane

azeotrope need plates in a fractionating collumn to even begin

seperation and then the amount needed in some cases is well

beyond a normal labs abilities hence the need for massive

petrolium cracking towers.

these are petrochemicals and I would probably think they are

already run up one of them towers I doubt any of us could

do anything to remove benzene.

and really again ?

food grade you don’t cook your meals in ghetto solvent that

has been distilled form a benzene mix.

whats the difference here.

I honestly think all products for making human consumable

substances should all come with a food grade cert and being

you are all doing this on a large scale and for comercial product

there should be a testing stage of all products that are used.

if one does not meet standard then it is to be returned and

not purified.

again what you do in research and for your self I could not

care less about.

but for open market it should be all food grade and if you

have impurities it is not.

so after purification how do you call it food grade if you do

not get it certified as such.

this is much like me working as a chef dropping your meal on the

ground then dusting it of and going don’t worry I got the

dirt out of it.

there really should be no discussion on this its wrong.

John Skyler (Skyhighler) Posted the following regarding quantity of mystery oil by brand.

I had the mystery oil tested for content. Here is a good example of the green alligators and long neck geese present:

C6H6 Benzene and C6H14 Hexane are both carcinogens, and both can form azeotropes with C3 and C4 alkanes like Propane and Butane.

You probably can’t see it at the lab’s printout resolution, but the Benzene content of the Mystery Oil sample itself was 306.5 ppm, which came from a lot of Lucienne lighter butane at a rate of about 15 ppm, so its concentration in the original butane/propane mix was low.

When we were experimenting with scrubbing Praxair Instrument Grade gas, we found that overall purity of 99.5% Instrument grade as received, was 99.9% with regard to contaminants heavier than C4.

We scrubbed that 99.9% gas by fractionally distilling it one time and passing it through a gas scrubbing cartridge supplied by VICI Metronics, to achieve 99.98% purity.

If I was trying to remove Benzene, that would be where I would start.

co distillation is the issue.

I was unable to find anything on-line showing that hexane is a carcinogen.

Many sources advised that hexane / n-hexane is not considered to be cancer agent.

If the variable contaminate exceeds the threshold of impurity stated on the COA, the COA is bullshit.

Why is it invalid should be the question you are asking… This is what we asked ourselves 7 years ago when we were trying to find a way to help our friends and family make clean medicine. Could it have something to do with the cleanliness of the container?

If suppliers are refilling cylinders without decontaminating potential back flow contaminate, sediment accumulations or other variable contaminate from the cylinder manufacturing process - a batch analysis COA from the refinery doesn’t mean much.

This is why we post pictures of dirty coffee mugs. It might be annoying to some, but the concept is basic and there is plenty of precedent across several other industries that would require a clean chain of custody.

redissolve in clean gas and run through magsil and t5? but if that doesnt work, you have now contaminated more gas as well.
if that doesnt work, into the short path.

Well maybe the MagSil is a bit much for expenses

Carbon works to scrub benzene apparently quite well

from the dirty tank through carbon into collection to boil into clean ready to use storage tank.

:thinking: I’m not sure if it does remedial work in the liquid phase

If it did, I don’t see why not, Solvent CRC pops in my head cuz I wouldn’t want to use that spool for anything else lol

Then boil to remove the scums as per usual

If it only remediates vapour you would have to put it between your boiling tank/collection and your pump/heat exchanger much like a sieve

The quote is even more surprising given they have some set of data to start with… :thinking:

My guess the analyses set would just go with

  • XRF (chemical composition),
  • XRD (mineral composition), perhaps two type of preparation, like powder and oriented)
  • CEC and leaching tests (what’s is sorbed on clay, and what can dissolve in water)
  • particle size analysis
  • putting the data together

There are some more kind of physical and chemical tests that can be performed to know to material deeper, but I doubt it goes that far regarding what manufacturers generally supply.

That should be less or about 4 figures, I believe.

5 figures is closer to what a small university team would charge to perform complex lab experiments with various bentonite, including many of such tests, some modelling and in-depth discussions as well.

How’s about a tio2 filter of sorts for the benzene removal. Pretty sure that’s what vici uses…

I was unable to find the study from a decade ago that I quoted either and note that it is not currently on the OSHA list as a carcinogen.

Basis of OSHA Carcinogen Listing for Individual Chemicals (epa.gov)

Our livers metabolize Hexane into 2.5 Hexane Dione, which is a neuro and reproductive toxin, as well as a mutagen, but not a proven carcinogen.

The purification we do is via media not fractionating.

I believe that’s proprietary, but I’m going down to the plant for meetings tomorrow so I will confirm what I can and can’t share and follow up with you.
