I think that would create a situation that would fight against the piston. You’d need a way to lock one out, a 2 stage basically. I have a 150 on my collection base and a cmep on my tubes.

what is the cmep on the tubes for?
To recover all the solvent in the tubes. After dumping a rack of tubes, I close them off heat them to 140 and recover out of the top in a seperate loop from my collection base. I only lose maybe a half a pound of butane per 4 tubes.

does it make it tougher to unpack the tubes?
Quite the opposite. They are completely dry by the time I unpack them. I use an air compressor to blow them out from the top directly into a contractor bag. Takes just a couple minutes to completely evacuate 4 tubes worth of material with zero labor, except for removing the bottom plate and turning a few valves. They never leave the rack. I can have them packed and vac’d before the first run is even finished recovering.

I’m not getting a ton of loss but always want it to be better. I’ve only run cmep and their larger green thing, that was replaced cause our mechanic couldn’t fix it (which has me questioning why we pay them). I know the majority if the loss comes from the column itself because any vapors making it up past the top of collection have no reason to come back down. Pretty sure I can borrow your idea of isolating the column and getting a more full reclaim if I do it separately after the collection is finished. Are you running jackets goose?
Blowing the post blast out was something that I had heard and the more I consider it the more I like the idea.
Yeah I am running jacketed tubes with hot water circulating. 95% of your loss is for sure in your material tubes, when you are pulling during recovery the phase change is keeping the solvent in your tubes. If you don’t have any heat to counteract that, it stays locked up and frozen in your material, just as you wouldn’t be able to recover your collection base without heat.
You don’t necessarily have to isolate it, I only do that because I heat mine up much more than I would my collection and I don’t want any undesirables dripping down into my collection base once the tubes get hot.
I rigged up one 240kbtu heater per collection and one per columns, all in a closed loop. This was before we finished building out the facility but you get the idea.

Glad it s working out, it really is the only efficent cost effective way to do it. I like the cmep to help the mvp, never ran a mvp im about to fire up a few cmepol’s here next week so maybe ill grab a mvp also

Grab a Corken you will need a good recovery tank thou
Still fighting that isseu
22kw coil with a jacket and still
Not enough to keep 45 psi on 100 butane runs
Not gonna be running a huge system at the moment, so a corken would be overkill and as much as i like to overkill all equipment its just not practical

i use a corken atm with 2 dry ice coils inline in acetone slurry…i shovel dry ice like a motherfucker all day but it works

I think I’ll be taking one of my CMEP’s out of retirement and hook it up to the top of the columns. I had that idea when I first came across this issue, but now that someone else mentions it I will for sure be doing it. Next obstacle is finding a way to melt the dry ice in the open-top jacket column. The best idea I have is to pour warm water through the top.
Yeah I’m honestly disappointed with the mvp 150 sucks compared to 4 trs21s its slower . My tank psi is too high and it sucks that the mvp can’t handle any outlet pressure . The little piston pumps rip compared to it . What a waste of 12k i just don’t run dry ice at all so thats my problem . It wasn’t an issue with the piston pumps . I even bleed my head pressure to a separate honey pot and its not very impressive . Oh well guess ill just have to get some dry ice . But at that point why not just run passive lol . It isn’t even worth it for crude let alone crc . Damn diaphragm pumps

What psi do the 150s not like, the original was nothing over 60psi head pressure.

I keep my recovery vessel at 5 psi and still feel like those 150’s are working too hard. . . They’re in the way . . . Just go passive or truly positive displacement . . .
Bhogart projects are hilarious …two vapor pumps and one liquid pump on the system I’m running, and it still requires nitrogen injection to generate enough pressure on demand (if you want to recover with any damn efficiency while running multiple material columns back-to-back) . . . And it begs for a -40°C or colder recovery vessel …yep just go passive.

Somethings wrong with your setup or pump. I can easily hit 2# a minute. What are you using for chilling and heating?
