Hi there, new to the site and running this machine. Today and associate of mine and myself were attempting to run a dry run to better acquaint ourselves with the equipment. We began by vacuuming the system, turning on our gas, turning on the back red valve on the rail, slowly turning the red valve on the extraction vessel, getting it to our desired weight on the scale, turning off the red valve ON the extraction vessel then letting it soak. We then opened our bottom green valve, opened our yellow rail valve, slowly opened our black valve on the collection vessel until reaching 25psi, then opened the green valves on the sides of the extraction vessel.Then we turned on our haskel. Everything was fine until we reached the second column to repeat the process. We got what looked like a “shower” of solvent coming out into the collection vessel from what seemed like the top of the dome on the extraction vessel. It also was not recovering very much of anything which to us meant to turn everything off. What could have happened in this situation? Should we have turned the valve on the gas rail OFF, or was turning the valve on the extraction vessel the right step? We just had training yesterday so I don’t think we could be far off. Thanks for any and all help in this matter.
hot water on while dumping second column? Its all about psi if your hot water makes your collection pot higher in psi than your tank is pressurizing your columns the gas will just slowly shower over like that
try turning the water off when you dump the column
what psi is it recovering at and what psi are your columns at
Are u vapor assisting the column before starting the next what’s your collection temp
what is your propane source?
@6teege6auru6 Yo I re read your post I run two meps by myself your opening the yellow vapor recovery valve on the rail and your only supposed to open that when all the tubes your running are done flushing and vapor assisted then u open the yellow valve once theirs no solvent dripping in pot so u can take tubes off and switch socks
running in an explosion proof environment I would hope?
Your expansion tubes r filling with liquid and has no where to go but into your collection pot…
@710enigmatic is correct you must make sure that the yellow bypass stays CLOSED until the very end of your run. When you are ready to recover from the top of your material column, and there is no more liquid in your coil is when you open the yellow valve. Your expansion chamber is your last stop before your haskell pumps, so hopefully you didnt hurt your pumps by allowing such a big mistake to go unnoticed for such a long period of time.
Thank you!!!
Yes, vapor assist was happening at the end of the three columns as well as dual recovery.
Thank you so much for the help and explaining it, both @Griffin.Labs and @710enigmatic. So, let me recap: After injecting our first column we open the bottom green valve open black valve and then both green valves (whilst leaving the yellow valve shut) then continue with injecting the next columns. Once final column has been injected and soaked, then open the yellow and move injection hose to blue recovery, then begin haskel? I’m sorry if i’m becoming redundant, I just want to make sure I am fully understanding the process and operation of the machine.
You are on the right track . After you fill your last column move your red injection hose from the injection coil to the second recovery quick connect, then open the red valve again on the top of the last column and leave it open until your are finished recovering from all 3 columns, once you are finished recovering through your collection vessel for the run, you can then open the yellow to pull that last bit of solvent from the top of your columns.
