So I run my system, then pull my material columns down into a vacuum w my recovery pump and heat.
How do I know when all the butane is gone and it's safe to remove the material?
If I leave the columns overnight, the pressure raises in them again to around 10-20 psi even after being in a vacuum w heat the night before?
I have been passing co2 through the columns and venting that outside to remove and residual butane but I'm still concerned it is being released into my room when I open the columns?
