Hydrostatically test it to 2x operational pressure.

everybody is brokering china steel unless its asme or made in usa by a trusted person. I was gonna be a steel broker prior to me even finding future but i got 2nd thoughts due to it being used for illegal purposes potentially. I didnt/dont know shit other than when i looked on alibaba I see all the same stuff for way cheaper. Its expensive to ship unless you buy it by the palletload and then its cheap.Also theres good and bad sources and you need samples and then the final product may not be the same as the sample so its a trial and error to find the best suppliers.

If anyone wants to get away from using dry ice to recover. Iāll soon have an item available that will save your pockets and be efficient!

Yea I love watching @Boomtownpharms equipment come to life. Always looks so nice and clean. Love all the hard piping. Hoses are overrated!

Quality hoses cost just as much if not more than stainless tubing too. Basically itās cheaper todo it right in this case.

Interested in more info, out of curiosity(I doubt I can afford something like that but DI is fuckin expensive and heavyā¦that looks like you donāt have to lift anything
Iām sure it will be affordable. Iāll tell you this, it wonāt be $100k and you donāt have to buy a system from me to purchase it.

You would need an initial chiller to get your solvent tank cold, but not a powerful one. Like a Julabo fp90 or similar. But as far as recovery, you will not use any chilling power or need dry ice.

For sure bro. I just ran 140lbs in a little over 9 hrs on a 20lb system. And my compressor on my chiller barely turned over (only when I added tane to my solvent tank)ā¦ā¦ thatās how efficient this piece is. This is only my prototype, the one Iām having done will be 316L stainless, and your choice of sanitary or Swagelok fittings.

Well I canāt find a reputable shop to make my piece and I donāt have the time to commit to making it happenā¦ Iām on the skirts of leaving the state of Oklahoma. But Iāll go ahead and put the drawings on here for everyone to see and maybe you can build something to replicate it.
I will say through R&D, you will have to have a lid on your collection column that has a minimum of 3ā dip tube on the incoming solution. Otherwise, The vac created from the recovery port will pull the solution through due to the solution being nearly at boiling state when it hits your collection column. (Donāt end up with a lot of your solute in your Sieve column!)
I would maintain a 15-20psi pressure to push the solution through the cross-flow heat exchanger going to the collection. Use a valve to be able to āthrottleā the flow coming into your collection column.
To be cheap, I would just use a standard cooling coil lid (like the ones found in solvent tanks {$3-400}), change the middle port of the lid to a larger diameter fitting for better recovery flow. So you would run cold solvent from your expansion, CRC, or material columns, through that coil going into the collection column with the 3ā dip tube Iāve mentioned earlier. Then after the boil off, run the recovery path through youāre Sieve and then through the middle top port that you made larger diameter. By the time it crosses (cross-flow) through that heat exchanger, it will already be mostly condensedā¦. Finish off with a Exergy 1/2ā x 1ā tube n tube heat X to make sure the minuscule amount of vapors are all condense and at near chiller temp heading back into your solvent tank.
Again, not much of any chiller power is used for recovery. Mostly just a back-up in case you put too much too quickly into your collection column with no more solvent flowing through the coil.
Good luck

Man Iāve been trying get someone to let me make a cross-flow condenser for recovery for years, glad youāve finally done it!

damn the fp90 is 60k smh. I was thinking this was gonna be like a 10k chiller or something the way youāre so nonchalant about it
