I wish the title of this thread was the mentality of the forum. It was at once. Ego is a son-of-a-bitch. This thread holds true.

Just got off the phone with Emerson/Copeland America. Excited about this next project Iâm working on. Iâm building a custom evaporator to get away from my AV30 ffe. This unit will incorporate the Cross-flow Heat exchanger design, with direct refrigeration on a new unit using vapor injection technology to keep things running smooth during ultra-low temps with high head pressures. The system will evaporate up to 500 litres an hour of ethanol using 30hp condensing unit paired with a 96kw Hubbell heater. Will have CIP and all to allow us to stay GMP certified and work towards getting our FDA approval so we can ship internationally next year. Iâll post pictures next month when the custom pieces are done being manufactured.
I also designed a system that requires only 144kw of heating power and 60hp on cooling power and will evaporate over 1200L an hour. It will use ambient temp to run a good portion of the machine. Now that Iâm back in Cali, the move now is to be the most efficient in power and consumables. 2025 will be a great year! Happy New Years everyone! Much love!
With all this being said, I will soon have a like-new gen 3.0 AV30 for sale that Iâll include Hubbell 36kw heater and Nordic 11.2 ton chiller and TACO pump. Asking $90,000 for it all. I also have other items that I havenât used at all that will be for sale. Location is in NorCal. Thanks!

Damn I hope youâve got a membrane stage in front of that. If not, youâre wasting a ton more energy/opex than you need to be.

Iâll be using this for hexane recovery. I wish to use membranes but havenât found suitable membranes for my usage.

Thatâs fair. There are a couple of acceptable-ish alkane membranes, but they are all extremely expensive, and we had the best results from designing our process in such a way that it didnât require an alkane membrane that would exclude cannabinoids.
We got the cannabinoids out of the alkane a different way, then used a membrane to remove the other compounds that we didnât want from the alkane, then sent the alkane back to extraction. That worked really well once we got it dialled in.
I was planning to validate a bunch of pre-commercialization alkane membranes for our industry, but then we moved away from traditional solvents and that project got shelved.

Yes, Iâve heard of certain ones that could possibly work and youâre right, they were nearing $10k per. I would love to have some just for solvent recovery, even if it did leave 4-10% of the product in the âcleanâ hexane. I would love to get on a line with you and see whatâs the best possible option. I do have some 4040 membranes I could use. Donât need to winterize, just need solvent recovery.

Does anybody have calculated and quantitative proof that a cross flow hx actually reduces the amount of work preformed by the chiller? Or is this just strictly anecdotal? Or is this just strictly anecdotal? I know the concept is used effectively w steam turbines at the power generation level.

I donât have data to back up my claims. I just know that my chiller always kept up with my recovery and really helped on pre-heat.
Any pics/updates on this project?

Ah, @Tech1145, always here with the GIFs and gas, never the science.
Interesting that someone who claims my patents are not valid also spends so much time trying to reverse-engineer and publicly post variations of it. Thatâs the kind of energy youâd expect from someone who smells their own flatulence and calls it innovation.
If you truly believed the tech wasnât novel, you wouldnât be trying to discredit it â youâd just ignore it. But here we are, with you obsessively trying to make it public domain post-issuance. That doesnât scream âprior art,â it screams caught off guard.
Hereâs a tip: when you spend more time trying to undermine than innovate, youâre not the inventor. Youâre the footnote.
If anyone wants to challenge the validity of the patent, do it through the USPTO like a professional â not by waving a GIF around like itâs a peer-reviewed publication.
Until then, Iâll be over here, building the future. You can keep sniffing.

Cool looking vessel. Using lots of different types of heat exchangers.
It looks like the plate exchanger on the right is probably the cross flow, correct?
How does it work?
Hereâs my guess:
It looks like incoming cold/room temp solution (hexane?) enters through the lower left fitting on the plate exchanger and exits through the upper left fitting into the tube-in-tube. It gets pre-heated in the tube-in-tube and then goes through that multi-valve distribution manifold (Iâm a little confused on whatâs happening there) into the left side tube-in-shell (or is it a jacketed column?) for primary heating.
Then it drops into the main vessel body with the stirrer.
Vapor flows through the large braided line into the plate exchanger (crossflow) where it imparts some heat into the incoming solution. Then it flows down and out the plate exchanger into the tube-in-shell main condenser. Liquid is removed through the pipe/fittings on the right side of the vessel.
Iâve heard you mention youâre using direct refrigeration on this project so youâve probably got the compressor outlet (high side) running through the tube-in-tube and jacketed column to preheat the incoming solution. Do you still need another external condenser for the refrigeration system? The TXV must be at the entrance to the tube-in-shell condenser and the compressor pulls on the exit port of the condenser.
What exactly is up with the multi-valve distribution setup thatâs on top of the jacketed column? How does it work?
Would love to see pics/vids of it all setup ready to go. Nice work!

Iâm over the road right now but will answer your questions and do a follow up video when itâs running during a test. I will say the multi distribution nozzles have been replaced now with a custom sprayer and I have a sight glass around it. No direct refrigeration on this unit, just pulling from cold tincture storage (~-50C). Exergy coil is the pre-heater. Liquiflo pumps I got on the cheap (Under $800 brand new off eBay). And the main heat flash under the sprayer is a bulb-like hot finger as to prevent clogging of crystalline product. cheers
