10lb Xtractor Depot CLS ( I know I know)
6” crc w/ 900-1000g (W1 or t5/t41/sil)
10:1 solvent to material ratio using n-butane
Push with nitro from solvent tank @40psi push from material column @50psi
I’ve been having an issue with injection, system doesn’t want to flow like a hose into collection, it only trickles/ has a light stream that’s broken by trickle. Sometimes it will flow very hard if I open the valve to filter dryer (molecular sieve) and only flows for 5 seconds or so. What could be causing this?
Your probably getting to the equilibrium in your system thats why opening the mol sieve takes a lil of the psi and lets more gas come in. Is tour collection chilled or heated while tour injecting
You dont push the columns with n2? I dont, sometimes ill let the tank empty and use the headspace charge push the columns but normally only for injection since the chiller is -40c+ i got no psi for injection
I cut the screen side off the crc screen gasket so it’s only the wire mesh and it flows perfectly like it should. The screen was compacted against the mesh so much that it wouldn’t allow a nice flow! Absolutely insane
So I grabbed a gasket support from glacier tanks, crc gasket kept ripping but also works to separate butane upon entrance to crc and make it hit other spots. Have that in conjunction with a sintered disk/ring combo that sits directly on top of powders THAT works like a dream.
