Hello
i know i will have advice for not use used coolant back in engine.
Im interested un the chemical process of removing oil from coolant , specifically propylene glycol (in VW)
Ive spill power steering oil in my coolant pan i was removing for a job. At least i will keep it to clean metal part as aluminium.
I know i can filter the fluid, but for the oil it seems a bit emulsified in the coolant, I think glycol is easily diissolved in oil.
Then i thought i could try to filter the fluid through a tshirt filled with Milkweed seed pod. Ive used those pods last year to clean an oil spill in my garage and it works liek a charms. Those fiber are hydrophobic but they absorb oil. my only concern is thatif glycol is dissolved in oil, i will lose it.
According to some tests, 155 g (5.7 oz) of milkweed fiber can absorb a total of 7 L (1.8 gal) of oil at a rate of 0.23 L (0.06 gallons) per minute, twice as fast as competing products made from polypropylene.
Last question, whats the best way to get rid of used collant after? is there an easy chemical process that neutralize ethylene/ propylene glycol ? or the only way is to bring it back to disposal center?
If Milkweed adsorb oil with glycol, then i guess it could be burned to hight temperature?
