150 psi rated loop
What’s the most propane I can mix with the n-butane?!
Is 50/50 to much?
My method I’m using now is-
Solvent tank in dry ice isopropyl bath (cold cold cold)
Chilled column with live flash frozen material (the good stuff lol😎)
Using nitrogen to push the butane into column
30 minute soak
Run more butane through
Nitrogen push in column/tank/honeypot have been maintained to 60psi on gauges. The nitrogen is burped out do solvent tank and honeypot to prevent the gas from getting between the honeypot and solvent tank particularly (during recovery). Solvent tank gets burped also to prevent pressure/mixing after running more butane following soak.
Getting rad results, but maybe a little more propane could continue consistent results. Maybe more propane could even improve quality even more?
