@kingofnights I tried to be cautious when opening the valve above material column, but the recovery vessel valve was wide open. Should this be done slowly or a quick open?
Left most valve wide open to let solvent into line, slowly opened right most to allow solvent to wash material column. Middle valve is for when I’m recovering butane after a blast/distill.
@cyclopath The column is 1.5" x 18". It’s posted to run 90-135 grams of material. I pushed just over a quarter pound, at like 123 grams of material, shake/popcorn buds. 5 cans of neon 11x at 300 mL a can. This wasn’t exactly what I washed over my material. From what I understood was I can distill more solvent than needed, just have to keep an eye on color change when doing the material wash.
Noticeable liquid butane, could see liquid in the splatter platter through the sight glass. Could see it bubbling up, evaporating off when put in the warm water bath.
My next thought was crunch some numbers and figure out minimum amount of butane I’d want to wash with.
cyclopath:
did you see anything like the same amount of liquid after washing material column?
there appeared to be similar amounts of butane in the collection pot after both distill and material wash.
