hey guys
issue is as follows.
Currently ive been using a chilling coil inbetween my storage and
material column to try and improve my final product,
needless to say i believe I have been yielding less because of it.
i nitrogen push from the storage tank at 100psi to move the chilled lpg
I get all the solvent out of the storage tank.
its dry when I finish my dump.
i use 25 pounds LPG for 4 pound run ( 6x24 non jacket )
is this not enough ?
questionshould i be closing off my storage tank as soon as the last bit of lpg flows out or should i allow the pressurized tank to let it flow through a bit, no? should i only reopen it after my soak and flush once my solvent slows down , as to pressure out whatever is slowly dripping in the column
i flow lpg entry with the dump collection valve open.
once any amount comes through I lock it off and let it saturate
eventually everything starts to ice up because of the chilled coil
NOW RIGHT HERE IS WHERE I FEEL LIKE I MUCK SOMETHING UP.
now once i feel like ive reached the desired soak time because
its all been covered long enough. or whatever.
I pull the dump valve
the solvent flows to the collection pot and its glorious !
(collection pot is has no heat applied during this process)
as the solvent flow to the collection pot slows i send nitrogen through t
the lines in whatver effort to push out whatever keeps dripping.
at a point it just stops completely, Did I chill the material in the
column with n2 and lock up all the flow?
at this point i vent out all the pressure in the system. b4 recovery
because NITROGEN IS COMPRESSIBLE NOT CONDENSABLE
(thank you greywolf)
turn the heat on the collection pot and begin recovery.
now thats my woes.
after the majority of flow is completed and dripping starts and i use
n2 to push the remaining fluid out .
I feel like it dries it out or locks it up.
