B80 seems my go to as well no matter what I try.
Just rig up a air compressor hose to go outside and vent all the nitro out
How much t5 tou adding, im just running straight b80 and getting great color and flow.
I don’t even weigh it anymore since it’s so cheap I just use like roughly 4 cups of each, try adding t5 tho b80 alone works but I get better results with both
Ya i dont weigh the b80 just a couple of cups or so, works great in thw column as well. Ill grab some T5 and five a shot.
They have released a more aggressive CRY product if the CRX was not sufficient in meeting your expectations. If you want request a free sample of the CRY product. Also did you follow this handy cheat sheet?
DO this:
Any hydrocarbon solvent will work.
Use a 6:1 up to 10:1 ratio of solvent to biomass.
Use between 150g to 250g of media to 1lb of biomass. (More is better for clarity!)
Use a 3" to 4" diameter column/spool.
Use a 5 to 10-micron screen or mesh on your column.
Run the column/spool directly inline after your biomass vessel.
Use MORE than you think. It is okay! You will not strip terps or cannabinoids.
Do NOT do this:
Run crude through our media.
Run distillate through our media.
Run ethanol or CO2 through our media.
Prewash or saturate our media.
Use any acids or saline to treat your biomass.
Add any silica, bentonite clay, or other adjuncts to our media. (it is redundant!)
On the pressure issue the finer the media the more pressure it will take to move the oil through it. Since this media is more coarse it should take less pressure to move the oil through it. I am surprised you did not experience this?
Question about Nitro Push-
If my material column is at 50psi and I want to increase it to 70psi via a nitrogen push to get everything through the CRC column, do I set the dial on the regulator to 70psi and it will inject the correct number of lbs to get the material column to 70psi and then I close the valve or keep it open until all the solvent has passed?
I’m going to evacuate the nitrogen via a quick disconnect at the top of my column prior to turning on the compressor, though I’m pretty sure if I wanted to I could collect with the nitrogen in and bleeding it off from my solvent tank. Though I’m not sure if that would be the correct way to go about it.
Just want to make sure I understand the pass through of the nitrogen into the material column that’s under pressure.
I always bleed off nitrogen from the collection pot once everything has been pushed through. I also bleed my solvent tank with a Venturi vacuum pump to get it back to negative pressure after pushing my solvent into the material columns.
As far as the nitrogen push, I always just use valves and a pressure gauge on top of whatever I’m using N2 on. I keep the nitrogen regulator set fairly high - about 140PSI - and then just open up the valve and let in as much pressure as I need. Use your pressure gauges to determine how much pressure is in your headspace.
@greggoose710 I am not sure who you got the sample from, but our SOP would suggest you needed more media. For 30lbs of low quality biomass you should use 7.5Kilos of media. You can either DM or DM the person you got the media from and we can work with you on it.
I followed the instructions I had, and been using CRC daily for almost a year now.
With that said, I have been offered a larger sample, I will try they new recommended ratio they seem pretty content that it will work so I’m happy to try it.
7.5 kilos of media for 30lbs of material??? Surely this is a typo.
100g/lb will get you water clear pretty reliably. For 30lbs you’re talking 3kg at MOST. I’ve been running roughly 50-70g/lb of W1 and getting gold to clear
They aren’t talking w1. They’re talking about a different media.
So do y’all prefer slow flow or fast flow through your Crc media?
Man yesterday I did a crc run and idk if I packed it to tight but the flow was so god damn slow that bybthe time it would reach the collection vessel it would all recover/evaporate. Got a small ass yield and took god an near 3 hours. ![]()
Is your sintered disc dirty? Sounds like it could be.
Shit could be bro, I honestly got a bit rushed prepping to column that I didn’t check that. We’lol see tomorrow. As for the flow going into the Crc. You think slow or fast is better? I imagine slower going through the clays might be better since the slow flow going down would really pass through the medias, what you think?
Well, I’m finding doing things like @FicklePickle mentioned give me a good run. I let my material column soak for about 2 minutes, then slowly let the solvent fill the crc with the bottom valve closed, once the crc is full, I let it dump at about 1/2 of what I would normally do on a non crc run. Couldn’t say the flow rate, but I do know I have to throttle the bottom valve of the crc or things flow like there wasn’t one.
Lemme find that post, he describes things better lol.
He doesn’t mention flow rate, but it’s a good description of what I said above.
Really, from my personal experience, flow rates with crc shouldn’t really be too much different from when you run non crc.
My flow is all dependent on what media I’m using, but I don’t like for my input to go any faster then an lb every 30-40 seconds.
I’d start with an hour or so with an ultrasonic bath for the disks (no heat obviously) then fully dry them. If I have time I usually go ahead and start this immediately after my run, recovery and then break down. I use acetone for my disks and if times an issue I will let them sun dry outside in a black box since black absorbs more heat and helps accelerate the process of drying out the remaining solvent used to clean with. I have started using a little trick to make sure that the disk is fully clear. I’ll pull the disks one by one and use 160 psi air compressor to make sure the air is passing through the disk(it’ll bubble), then it’s into the oven or goes outside into the sun for at least an hour or so.
Faster flow rate for me was 60lbs solvent in 12 minutes, but I won’t go at that speed ever again for many reasons. It’s all about the resistance time to me and that’s why I have been getting cleaner results and higher terp retention. I will post more data for others to compare with on almost all chemtek products I’ve used and established benchmarks on time and pressures that’s worked out for me.
@Waxplug1 has me sold
@StoneD is officially a chemtek user!
The flow rate plus terps retention is awesome
And it’s the only way I know I could go completely colorless w ease
I’ve used it about 10x now and am in love
W1 for crystalization win
I’m curious to play w w2 and w3 and jar it up see what happens
