HELP!!!
New member, have definitely skimmed/read/absorbed/learned from the site in the past however this is my first post, first thread, first handle.
Greetings...
So, have been running a pair of 2lb CLS's passively for a while, took a bit to work through numerous newb issues, mistakes & tribulations. Got my system down and recovery times Andretti quick with gluttonous amounts of dry ice and silly amounts of elbow grease, but got it down.
Decided what the heck, grab a couple rec.pumps one sleeve/ball valve to start and upgrade the necessary parts to go active.
Had issues all over the place on the first day, starting when I set up the dewaxing sleeve & ball valve...
I don't soak at all, but flow about three column volumes LPG through the material.
- How long is an acceptable soak time before dropping your tane into column?
I leave the ball valve open until pressure drops to around -15" Hg
- If not running active, do you close ball valve after allowing tane to drop into column before starting to recover or keep open?
Less of an issue with a recovery pump. Just leave both the vent and dump valves open until -15".
- How do you know when all tane has flowed through to your column without a sight glass, and what can you do in order to help speed this up??? I had huge issues with wayyy too much butane left in material tubes above the ball valve multiple times. Every time actually, even after allowing way more time to flow through than normal.
I put two volumes from the bottom and one from the top
- If/when going active how long should you run it?
I run the pump constantly
- Should recovery pumps run full time during recovery/active extraction or should you toggle a bit when pressure levels reach 0 on gauge, wait for some to build back up and then turn pump back on?
I appreciate any and all reply's and fully encourage any other applicable thread links to be posted rather than rewriting information that has already been discussed, though Coles notes would be greatly welcomed as I'm really having a difficult time wrapping my head around these issues, can't figure this ball valve/tane flow situation for the life of me and losing these huge amounts of n-tane & end-result is costly... Help!

I would dump the Molecular Transformers and use 3/8 or 1/2" X 50' stainless tubing coil. The transformers ID is constricting and surface area limited.Gage's on my unit are slightly different than the ones it sounds like you are running Graywolf, would you suggest switching over to yours for reasons previously mentioned?

High pressure shut off on the pumps suggests that you have non condensible gases in the system, typically atmosphere. Burping should fix it unless you continue to aspirate air.Now, on to the issues...
Holy crap, talk about almost starting from scratch. So many little problems I ran into that again had me really scratching my head.
LPG flow much better running the recovery pumps, strong point greywolf and brought much relief.
Biggest problem last night was recovery of all things, which is so strange because the first night running the pumps/sleeve recovery was a breeze, made me wonder why I hadn't been running pumps all along and really was the only thing that seemed to go right.
Last night, absolute nightmare.
This time round I left the ball valve open entire time which definitely allowed for better LPG flow and in theory a far better recovery ability so I dunno what was up but for a real long time nothing was coming out.
Gage stayed around 20, pump kept cycling on and off due to a high pressure shut off on the TR21. For a bit I thought I may have sucked liquid into it which thankfully I didn't.
I watched liquid levels through the sight glass into the column rise and fall numerous times which was totally strange.
Nothing going into tank, pump running.
Tried burping it a few times, didn't do much if anything, then decided to try and pull recovery through the top valve on unit that I use to wash which actually started to pull.
When running my previous passive, heavy dry ice and aggressive tank agitation method I would commonly toggle between column valve and material tube valve intermittently with great results so this didn't surprise me that it was working, other than completely surprising me that it was working if that makes any sense as it was completely stale for like an hour.
I'm wondering if perhaps my tank wasn't cold enough as now I have drilled through the top of a freezer and have it placed in there with pump feeding it as opposed to elbow grease and dry ice.
Still tho, wouldn't/couldn't explain this outright block that seemed like it would never pass, or the multiple tane liquid levels rise and fall within the column so drastically.
Questions:
Hopefully graywolf sees this as I am humbly hoping for follow up with his generous answers and insights already givin earlier in thread.
Send me a picture or diagram of your plumbing and I will tell you. It is typically the valve at the head of the column that you open for top flooding or venting when bottom flooding.
- When you spoke on leaving my vent valve open, is this something equipped onto mother CLS I'm running? And if so which valve would it be?
That is how I do it.
- When running active should I be creating an absolute loop from tank through to recovery and back to tank?
It won't work as well as an ice bath and typically isn't NEMA 7, Class I, Div I explosion proof.
- Is a freezer a viable option for tank to sit during extraction w/pumps being used
Dirty peeecture to save a thousand words??
- How should the valves on my particular CLS be used, I'm unclear of how the t'd off valve should be manipulated
Once again very, very much appreciate any and all insights as well as taking the time to read my thread. Especially these last few posts as I was up way late and running way behind for an appointment which tends to lead to my writing and/or thought processes a little all over and not nearly as organized as I would normally compile.
*will add/edit more once I'm back and re-read posts...
Thanks for the input.
I would dump the Molecular Transformers and use 3/8 or 1/2" X 50' stainless tubing coil. The transformers ID is constricting and surface area limited.
I use a JB M2-250 compound pressure gauge, which shows both negative and positive pressure.

You appear to be missing some connections that I put on mine.
High pressure shut off on the pumps suggests that you have non condensible gases in the system, typically atmosphere. Burping should fix it unless you continue to aspirate air.
Where is your sight glass in the system?
