I’m getting ready to piece together or preferably have a machine built. I’m trying to get my recovery to ideally 2.5-4lbs of solvent recovered a minute going to be to passively recovering because recovery machines are slow, too expensive For good enough ones and down for servicing constantly
Will be using n2 assist also
Currently on the drawing board.
2x 150lb jacketed solvent recovery tank
2x condensing coils
3x rolling racks for columns, tanks, & collection
Either 4 or 5x (8”x60” jacketed material columns) aiming for (10-12.5#material per column)
1x (6”x60” dewaxing column) w/ (6”x12” or 24”spool) for crc W/ or indofab v2 6” crc
2x @Indofab sintered disc filters 3&5 um
- all hoses, gaskets obvious necessities,
Filter plates for all columns
This where where I have some questions on collection vessel.
2x (12x60”) jacketed collection vessels
3x (12”x48”) jacketed does I can have 2 to collect into and if I wanted to dewax or crc runs I could run them into the 3rd
Or 1 huge collection vessel which is gonna run me into problems with long heating and cooling times.
There’s a chiller @Dred_pirate linked to me that I’ll link when I find it again that I’ll be since I’ll be recovering passively instead
Heater I haven’t picked yet comparing prices and power right now.
So In theory with this new machine my plan is to
Be always running cold over each column with anywhere from 4:1-7:1 solvent : material ratio
so about 40-70lbs Of solvent per column
200-350lbs of solvent per run also using one by one using of the victor regulators pump 10psi n2 to push and solvent through.
Another question here, if I’m running them single column one after the either I would be able to just soak and inject the column then repeat that over with each column then at the end get rid of that n2 from my collection Vessel before I recover.
Now when I go to recover I’ll be bringing my recovery vessels to vacuum and relative negative pressure with the chiller before hand then heating up the columns and collection vessel then thermodynamics does its job open collection pot to recovery tank with coils in slurry as well
in theory with enough heat and enough cold you can get up to 4-6lbs solvent recovered some say they are getting I’m hoping for 2-4.
any advice appreciate what’s really cutting those recovery numbers and making the difference when recovering passively
Basically looking to get my production to about 50# material a run every 4-6 hours= 8-12 hour days at work and being able to max production at 100-150# a shift.
With the 2 solvent tanks and collection vessels it will be easy to have a collection vessel or recovery vessel readily available to swap out but is this also inconvenient should I just go with the 1 huge solvent tank and 1 collection vessel?
