methods of detecting glycol in used lubricating oil?

methods of detecting glycol in used lubricating oil?

(OP)
I hope I am in the right forum for this question. Does anyone know of a quick method of determining whether a batch of used lubricating oil has been contaminated with glycol? I've heard of some field tests such as the blotter test or patch test but was curious to know if there are any other faster and more accurate test available.

Thanks for any help/advise.

RE: methods of detecting glycol in used lubricating oil?

FIRST OFF: My lawyers make me say this warning:  Anything dcastos says is all in jest and should not be followed unless backed up in writting by the readers Lawsyer, Doctors, state PE, and other advisors.

Taste it. spit it out and rinse with water.  Glycol will taste sweet.

Has your wife agreed with that?..."other advisors"??? Mine sacked the Lawyer, Doctor, PE and instead hired my mother-in-law.

ok then...thanks

What about removal of a small amount of glycol(~5%)from used lubricating oil? Anyone?

...and yes dcasto, it did taste sweet...j/k

RE: methods of detecting glycol in used lubricating oil?

The vacuum dehydration processes are today the most effective ways of removing the contaminants (including glycol types) from the lubricating oil. There is a whole industry today recycling the used lubrication oil. A plant using a small vacuum pump and a few small stainless steel vessels can recycle and re-generate large volumes of used oils from stationary engines, turbines, long haul transport companies, you name it...
However, if you got 10 gals of contaminated oil, chuck it. Don't taste it, it's horrible..it makes you turn to grapa..
