Does anyone know if using a blended solvent for a long time results in the blend changing?
Say your running a 70/30 butane/propane blend, you fill a 100lb solvent tank and use it for say 30 runs @ 24lbs of solvent per run, Every time you recover, you take .5lbs of solvent out with your pour. If propane evaps quicker than butane, will the .5lbs of solvent poured out with each run be mostly butane? And will your ration eventually go from 70/30 to 60/40 and so on?
