I was just thinking about how much pump oil I go through (20L+/mo) and got to wondering what else it’s good for/how to down cycle it.
I use the spent oil in vacuum pumps that I don’t need as deep of vacuum for, and it slowly evaporates from a couple of those.
I was Also thinking it might be a good heat bath oil! I have a jacketed still for evaporation, as well as using it for the jacket on a hot condenser for my short path. (I should check gasket/hose compatibility now that I think of it). It’s got quite a high boiling and flash point!
I hate waste! Anyone else have any good ideas for the stuff?
