Hey guys,
So I have been bouncing around this forum for while now and just made the transition from distillate to crc bho. I have a 6 inch system, with nitro, 6 inch crc and a cmep.
I have been doing pretty well with my runs and can run approximately 3500 grams of material in about 45 minutes. I have been reading that people are getting insane recover rates using passive systems. Up to 5-6lbs of recovery per a minute.
How is this possible? I’ve read about
maintaining a proper sealed system
Removing the recover tank from the ground
Dry ice slurry
Difference between cryo and Sub-Zero temps
And a rudimentary understanding of gas exchange laws.
I’m just having a hard time accumulating all the small steps that lead to this large recovery rate.
Ps… I know ethanol extraction pushes the largest volume. I’ve just had customers complain that they can tell a difference. Whether or not that’s true, sales drive my market.
Well they are getting insane recovery speeds like that because they have spent alot of money on there passive recovery system. I’m running a basic 3/8s hose and coil system and have a dhiity recirculating heater and I do 50lbs of solvent in 1 hour to 1.5 hours depending on conditions. Pumps are loud and cost money to rebuild and can hemp contaminate your gas. Which are the main reaso6o switched
+1 for passive, you’re not limited by the capacity of a recovery pump and with quality equipment, enough heating and cooling and some good insulation, you can achieve incredible efficiency. I insulated a large loop for a friend of mine and at the time it was recovering upwards of 6lb/min, god only knows how fast he can run it now.
Im currently converting my setup to passive, I think Im going to use a separate 25lb warm tank of butane to pressurize and push solvent from the prechilled solvent tank to and through the material spool.
I wonder if there are reasons that others use nitrogen as there push gas that Im not seeing?
I’ve thought about a “hot” tane push because n2 loitering in the system could possibly slow recovery. Can’t purge n2 from your sight glasses. That is, in my ocd fantasy engineering apparatus in my mind. But then I still would like n2 for clearing vapor from the material column before opening to discharge spent biomass.
Anyone know why I couldn’t have a lid built for my recovery tank that has one or more dry ice wells? I mean 1” or 1.5” closed bottom tube extending down to the bottom of the recovery tank from the lid, to drop dry ice into. -70 could recovery propane down to vacuum pressure. And how many wells could you fit on a 6” lid with ports gauge and glass. @Killa12345 ?
I have something similar; a 36"x4" spool with a closed ended 34"x2" spool welded to the bottom of a 4"x2"cap reducer(the two inch tube is the DI reservoir) , Its got 2" ports on the top and bottom of opposite side on the 4" tube, its basically a big dewar style cold trap.
