... and the solvent in the tube goes round and round

put it on a crank and pedal it like a bike! :joy: :rofl: :joy:

a closed loop ā€œfuck-it bucketā€ is an interesting thought

It works. Definitely works. Works great with heavy alkanes and alcohols. The solution to the heating problem is of course to put a heat exchanger to a chiller after the pump discharge. Havenā€™t ever tried it with light alkanes

How do you sonicate an LPG extraction system in a C1D1 environment?

at 5:1, do you think weā€™re close enough to the saturation point that this is required?

flowing 5lb a min for 10 min would give me 50lb solvent over 5lb of material.

should one not expect that flowing 10lb a min for 5 min would give a better yield than soaking with 25lb for 10?

didnā€™t @Graywolf suggest something along those lines?

P&ID is crude, but something like this essentially?

ive always run alot of tane over a small column and still get returns after re running = 10 grams per lb maybe? But its for a gummy bear and I dont like waste. If i see trichs under a scope ill rerun it.

I mean if you really want to get technical how are you even going to hook up a pump in a c1d1 when you canā€™t change anything on the system here in CA

You mean like, a compressor, or a vacuum pump?

This

that could be approximated by connecting the exit of column one to the inlet of column two, two to three, three to four, four to oneā€¦ which allows as many ā€œre-extractionsā€.

I did give someone the ability to play that particular game. they gave me permission to remove that capability. so Im guessing it was more trouble than it was worthā€¦

pretty sure they didnā€™t keep the ā€œfirst cutā€ separate, but letā€™s be honest, it would have been identical to ā€œall of itā€ as currently run.

Well, thatā€™s why I had to get something equivalent to ETS in MI. They are certified to be used with a Corket T91. So, no alterations are necessary. Same with the PIAB.

Funny. Thatā€™s how those first bhogarts with the manifold worked, recycling liquid back thru the columns. I never really saw much of an increased yield

from one column to the next?

then not seeing a decrease in yield might be data.

sounds like you need a butane falling film evaporator

This is very similar to how commercial hexane moving bed extractors work. The material moves counterflow to the solvent, meaning the feedstock that is least-depleted is first washed by the most laden solvent, and it continues forward until nearly completely depleted where it is washed with fresh solvent. This drastically reduces the required solvent and I really want to get there with the barrel-tek design

Edit: skip to the ā€œthe solvent extractorā€ section for a better explanation of what Iā€™m saying
