Butane membrane? Anyone seen this?

Fight into the falling film game?

English please

We all couldn’t give a sqit about the squabble & who said what.

Lets focus … Do you have a working n-butane membrane yet ?

But also…

Is there a lot of energy savings on desolvating with butane?

I’d think the dewax is worth it, but is there a ton of KW thrown into the phase change with the evaporation at room temp?

Obviously on scale I guess it’s just another solvent, but I’d imagine the savings are considerably less relative to hex/hep/alcohol

The membranes are pressurized. Why would energy be needed to keep butane a liquid?

Or am I misunderstanding your question?

He’s asking if a membrane for removing solvent really saves a lot of energy considering butane evaporates at room temp, compared to the increased savings on other solvents.

That makes more sense.

In the end I imagine it would, assuming you’re in it for process speed. Most people don’t want to put so little energy into evaporating the butane that it takes half the day. It certainly seems like membranes remove the need to put enough energy to induce phase change at a similar rate of speed.

I’d like to see a race between a membrane and a falling film.

I actually think the most exciting application for membranes are in use on a closed loop system, super excited to see proper dewaxing, terpene separation and a whole lot more to come in the future. Being able to buy one and slap it on my system would be dope as fuck.

I’ll pass on bringing butane to 1000 psi or whatever

Yall never felt how hot butane is at 100 psi and it shows

You’re right I’ve never had to get my system or any other up to 100psi to make it work properly, so I have no experience with that but I’m assuming an appropriate sized heat exchanger could make it work, and what about inert gas like nitrogen? Isn’t it possible to use that to pressurize? I’m asking because I genuinely don’t know anything about membrane systems, not to be argumentative.

I dont really know but 100 psi is scary hot

100psi from cooking the solvent to create the vapor pressure? 100psi of n2 isn’t hot. I mean I understand that pressure equals heat on some level.

Can you clarify that further for us. You know in layman’s terms

I guess you could be right maybe the pressure is generated from an inert gas and has nothing to do with the solvent. I assumed a transfer pump would compress the tincture into the membrane. I’ll just see myself out of this convo

A couple different ways for us to look at it. Lol.

We’re conceptualizing. :call_me_hand:

I know nothing about membranes but when i would vapor push with 100+ psi butane you couldn’t hold onto the columns they were so hot. Cant imagine how hot it would have to be to get to 1kpsi, i was using 2 stingers for vapor push bath and they get hot.

Membranes are generally running over 400psi, at least with current desolvation ones. :neutral_face:

At 550 psi if you don’t control the temperature of butane below 152C it will be a supercritical fluid.

Below 152 and above 550psi it becomes a super-compressible liquid.

Definitely beyond the realm of typical thermo you would apply to a regular closed loop—when you involve compressibility shit gets WEIRD

shhhhh, some wook is gonna load their boss’ supercritical extractor with butane now…

There’s a co2 license for sale

You definitely would not generate that pressure by heating it. It would be done with a pump and backpressure regulator. Not to say that it wouldn’t be very interesting to see what would happen with supercritical butane, but that’s an engineering challenge that I don’t think anyone going to throw themselves into right now.

Might as well just start making bombs :man_shrugging:
