You start runnning into recovery problems 4" and above. It would require applying some sort of heat to the column to fully recover. I have noticeably more loss when using 4" as opposed to 3" columns.
Why is this?
I have yet to run my 4"x36" column so column heat loses me..
When you dump, does the enriched butane just stay in the column somehow? Does the bottom freeze shut or something?
