What is the point of saying it was available for that price in the past? Thca Diamonds were $100 a gram in the past, but stating that does nothing for us in the now!
Residence time when distilling tane out of your material columns is key, having multiple material columns helps for sure

Could you elaborate on that a little more please? Thank you
shoot material column 1, warm it to promote pressure, send that psi to your corken
while the above is happening you can technically start shooting material column 2 if you have the cold butane and by the time you cycle to column 4, the 1st column has been on recovery for hours, you will want to keep the pressure up to feed your corken because they dont like to be used as vac pumps

I cant let a single column warm up, only option would be to turn chiller pump off and let everything warm up. Yeah i donât let corken run without some pressure feeding it, gotta do the mod on it soon so it can suck. Thank you for the response and info!

Definitely donât want to be a BLEVEr, thatâs why im asking here and appreciate all the info and responses! Thanks guys
that controlled ignition of atomized fuel is very impressive

Unlike unpredictable market swings, our sales are regular and rotating. The point is making you aware just how much money you can save if you catch the next one. This month GoodFast is on sell for 30% off all January. I wonder what next month will hold? To find out be sure to swing by:
Even when itâs not on sale, though, youâll save money. Save $40 today or buy it when it goes on sale again and save almost $80.
As far as getting the puddle out, you can at least push that forward or into a separate vessel just before opening your material column, but you wonât be able to get much dryer even with a recovery pump without the addition of heat or by pulling a vacuum on the column with that pump. The process of evaporation is only going to cool those already cold columns further.
At least doing it this way youâll be able to safely pull your columns back down to a full vacuum before beginning your next run.

Does your EX-40 have the hot gas loop? Will be in-between the recovery pump and the lower condensing coil. Right before the coil. A ball valve with a quick connect fitting. If so, use that instead of the Nitrogen push. Push that hot gas into the top of the column. Will build pressure as well as heat the column. If yours has it then he would have sent a steel braided hose with male quick connects on both ends. One end connects at the hot gas loop right before the condensing coil and the other end connects to the female quick connect at the top of the column. Close the valve at the bottom of column and let it build pressure. Let it get to like 50psi and then open the bottom valve to burp it. Youll see it blow a bunch of butane into the collection vessel and then slow down to a trickle. At that point close the bottom valve again and let the column build pressure again. Repeat as many times as needed. I can usually get down to less then 10lbs of butane loss across all 4 columns. Thats with a wet pour.
Iâve always imagined that it just made sense to have a hot-rack for your socks. a column or 2, kept warm, rip your socks out of your material columns and straight into these and recover till the next swap. Wasting solvent is silly.
That sounds like a fuel air mixture waiting for a source of ignition.

sucking a bunch of oxygen into your solvent tanks is even sillier though.
A lil nitro purge never hurt no butane lol
If your lab has a butane distillation system, itâs easy enough to add some recovery columns to that without slowing down production.
It helps to have a space at the bottom of the column. Assuming your pushing CRC and going slow.
I used a screen gasket at the bottom of material column. then even a 6x6 wth a hemi cap.
This allows the sock to drip while your pushing the last bit of butane out. that can give you 5-10 min of the sock being above the liquid layers and drip drying.

I donât have jacketed columns. Mine are 6x48 and I use the seed heating mats wrapped around and around. Overlapping them and taping them up really works. I leave the columns being heated over night and it pushes through the crc and into the collection tank naturally by morning. If you have a passive system and only aided by a pump as I do you can leave all valves open for 12 hours and nearly all butane will recover into the freezer. Then turn on the crc heat mat and use the pump until you get down as low into vacuum as possible. Most of the moisture seems to travel up the material column and what does get through seems to get caught in the filtration powder.
Youâre dangerous
Thatâs all fine and dandy, if you only need to get one run done per dayâŚ

Might as well invest in jacketed columns at that price.

If you want to be cheap, wrap a hose around your column (one that is grounded and wonât generate static).

Attach an ignition source to your pipe bomb and leave for the night! What could go wrong?!
