Your running warm n tane pushed with propane…this makes me curious.
Why do you run warm solvent as opposed to cold?

Because the custys can’t afford it

Maybe you’re referring to @Roguelab who suggested to use propane to strip volatile, then extract cannabinoids

I use dry ice and used to push with nitro. Now I just have a small 10lb butane tank I heat lightly and push through my material column or dewax column. No more burping the nitro. After I did it the 1st time I never used nitro again.

Try making that a 10 lb propane tank, no more heating!

Will that build enough pressure to get through a crc?
I have switched from burping from collection to vacuuming the nitrogen out from the recovery tank.

With a large fresh w1 column, yes. But on run number 2 or 3 you get clogging of fats

+1 on this. I been running all fresh frozen and build plenty of pressure and pick up very little fats and my dewax column holds as much as my collection pot. Right now I use a Iso heavy iso/butane/propane blend but want to switch to a propane heavy blend so I am gonna order propane and start using propane for push and then see how propane heavy I can get my blend as I want the most terps. I would rather leave a little THC than those fresh frozen terps yumm.

Try straight iso.
Butane yields with propane terps. Imo (yes I have ran nearly straight propane)
The BP is easier to work with too in comparison to propane (sure you are already aware of this)

Nothing like watching 300 lbs of liquid butane get pushed by 1-2 lbs of propane though

Not arguing about the push! Pretty bad ass.
Just saying why I like using iso as my primary solvent.

I’ve actually been doing something very similar, I thought that this process was what the kids called a “hot vapor loop”… Or some such similar shit…

Is using your recovery pump and pumping the gas (pre coil/condenser) back to the top of your material column.
If I’m wrong someone please correct me. This is my understanding of it (I run passive, so not speaking from experience)
I think what you are doing would just be called a warm/hot vapor push, not a loop

What I’m running now is close. I mixed 12lbs 50/25/25 butane/iso/propane and mixed with 23lbs straight iso so about 80/10/10. Now I wanna try propane heavy to compare. I’m getting 4% with my current blend/strain.

Please keep me updated on how you like the heavy propane mix.
Looking back on my propane experience, I would have soaked for 20 minutes instead of the 5-10 that I did. I was 3-4 percent less on yield compared to n-butane, running the same material and parameters (hope that’s the right word lol)

I will. I am getting 4% fresh frozen so more like 16% if it was dry. I have never soaked 20 mins. I only do a 5 min soak. 1st propane heavy run will be a 5 min soak and if yield is bad but no fats/waxes I will try a longer soak. Gonna run the same strain so will be able to get a good comparison. Hoping the yield is close but mostly interested in the difference in the terps. I live for terps LOL.

Neither had I. Until I did it with isobutane. I’m sold. Lol

Do you have a sleeved column with a di slurry in it while you’re soaking?
