You could then blow off (into another large cylinder) about 10% of the gas, check it with a PT chart and if all good reuse the gas. Most of the non condensable gas will sit on the top.

i don't think there mutch left to recover. you can presurise the condensor or evaporator whit NGO, repair the leaks, triple vacuum and refill whit exact amound of refrig. a dirty job, but rewarding if it is nicely done.

There are many ways of recovery!
only if gas is present!
If gas is leaking , inside gas will not be
contaminated.

Good chance if it's sucked in a gutful of air, the oil is going to have a stack of moisture in it. Make sure you treat it like a burnout and put a burnout dryer in and try and get rid of the acids and moisture once you have the evaporator sealed up.
