IVe been scrolling thru threads now for weeks. lol. Finally need some answers if you guys could help would be great.
My System: Jacketed Solvent tank connected to jacketed Material Column. (my Chiller is broke as of right Now. So i have the solvent/recovery tank in dry ice. ). From the column goes into a CRC Stack. 5micron mesh at the bottom. two filter stacks inbetween with filter paper.and final column for crc media. its a 4 by 18 inches. That travels to the recovery tank thats connected to coil and recovery pump.
i have 5lb material column, Note: only the coil and solvent tank have dry ice surrounding them
First question i have is:
At 50- 60 Psi how long does take for your flow to finish into the evap tank so you can start recover. It seems i had to burb it quite a lot to get all the butane out of the CRC stack and column. took quite some time. Im trying to figure out if i had the CRC
column packed to tight or not.
I was asked to USe Cry. I only did 2 runs so far thru the 5lb material column. the first time i used the recomended 250 grams per lb of biomass. Stilll ton of yellowish/brown/blackish. Second run we packed the crc column up to about 1/2inch from top and did another run. The color is still dark dabish color it did lighten up more but not white/yellowish like crc usually produces. So, Is Cry just a Waste of time and do i need to switch to b80 celite mix.
Im really needing find solutions to the problems im having. in next week or to. On Trim run of 5lbs im getting like a 2.5% return that not clear. I know im missing something here. ANy help is really appreciated and needed.
