35 min recovery time closed loop active

Hey all so I haven't posted on here for long time but I thought I would share some knowledge of how I cut my recovery time from almost 2 hours to 35 min....

KEEP IN MIND MY BHO IS PUT THRU ROTARY EVAP PROCESS SO I DON'T MIND BLACK BHO.... DOING THIS MIGHT MAKE YOUR BHO DARKER...


I'm using standard Bhogart 5lb active closed loop unit and recovering with cmep refrigerant pump... I use a blender to grind up material. This allows me to fit 7lb in my column. Im using cmep recovery pump and just bought appion g5 but I'm not using it yet. ..Running about 40lbs of butane.... For weeks i have been improving my system but recovery time was my biggest problem... just today i purchased a 500 watt aquarium heater and it has greatly reduced my recovery time by keeping my water at constant 95-105 degree.... Again All my oil is put thru rotary evap so I don't mind making black/amber bho.... so in conclusion keeping the water above 90 degrees drasticly reduced my recoveru time...just thought I would share this tip for anyone that is experiencing long recovery time like I was.

We've run the Mk III as hot as 210F for maximum recovery speed, when we're extracting bulk oil for medibles.

wow really...b hogart told me it wasnt safe to recover over 125 degree but if your doing it no pRoblems then I'm going to try that. .. how much butane are you running?

BHOgart could very well be right about their system, so I will let them speak for themselves. The limit on a Mk III is the 6" clamp, which is rated at 300 psi.

The higher the pressure, the faster the pumping rate, because the vapor is denser under pressure and the pump volume is fixed.

The boiling point is suppressed some under pressure, but not enough to cause the boiling point of the butane to get much above 32F, as long as the recovery pump is running, regardless of pot water temperature.

Except for dumping a cold column into a preheated hot lower pot, pressure usually stays under 45 psi. It typically stays under 100 psi even dumping, and quickly goes down as the remaining butane chills the chamber.

i think im doing something wrong im experiencing psi ranging up to 250! running active =(

no lol. Grey, i use a 70/30 butane propane mix. my solvent tank after recovery is always ranging up to 250 if I dont burp it off . The line runs out of the collection through the drier/pump/condenser So i thought i was doing it right. I even take the condenser out for the last bit of recovery and put it in hot water so it can gas but i feel like burping off that vapor is also losing my fuel.

I feared I was leaving too much solvent in my column so I learned i could use a little bit of nitrogen push on the liquid line to push the last liquid through and down the column while the actual siphon line was closed, But I dont think Im doing it correctly. When I read your words on the subject you stated after you push it through to burp your collection pot to atmosphere before you continue to run the recovery. i felt like after doing that push that burping to atmo was aiding to the loss of much fuel via vapor? Would it be safer to just run a T from the out on the recovery to loop it to Push the last bit , Or is there a better way?

also my column isnt "iceing" up like ive seen on some peoples runs does that mean my fuel isnt getting cold enough?
