I have a closed tank. I pull 20 hg on it at 160 deg. I have a sight glass. How do you know when the methanol is out?

The methanol is sufficiently out when it passes the flash point test at 230C. A flash point tester is a necessary piece of equipment for you.

With that much vacuum (and good circulation and spraying) I would guess you could achieve ASTM at less than 190F.
