Pressure issues with gas assist with Passive

It was the plumbing for

heated the columns to 150F during recovery

that I was hoping to see again. Pretty sure you’ve posted it here or elsewhere.

There are some links over here…

@Graywolf

Once I’ve recovered to -15" Hg, I valve off the columns and recover them separately, while simultaneously heating them to 150F with hot water through their jackets. At -22" Hg recovery, I switch to high vacuum pump and pull to -29.5, before backfilling with N2. I then pull -29.5 HG a second time and again backfill with N2. The material will contain less than 1% LEL.

And I’m with @pangea

@pangea

I could have sworn @GrayWolf posted a design that uses a air pressure to push/evacuation the glycol to a reservoir, then switches to hot water, I cant find it so maybe im out to lunch

Maybe it’s snack time?!?
