dry out oil
I had to dump the trans-hydraulic oil out of a tractor today. Its
contaminated with water. I've always just replaced it before, but the price of oil has went nuts. And I'm a bit short right now. I'm wondering about putting it in a metal bucket on a hot plate out in the field. If you heat it to say 200, will it drive the water off? karl |

You want to "decant" the water first. Get a 5 gallon can and cut the "bottom" out of it. . Solder a small valve into the fill cap. Invert the can and fill with oil. Let it sit for an hour or so and open the valve to drain off the water. Now you will have 90+% of the water removed. Let is sit some more and see if any more settles out. If not you are pretty well set to go - A whole lot faster and simpler than cooking all the water out. warming it up GENTLY to no more than about 215F- 220F won't hurt the oil and will drive the last remnants of moisture out of the oil if you want to be fussy, or put a few bags of Silica Gel in the oil to suck out the last of the water. |

I would just heat the oil in a boiling water bath. i At 215F at sea level water is vapour. At 210 it's just hot water. Somewhere in between there the water trapped under the oil approaches it's "local" boiling point and starts rizing to the surface - and the localized pressure reduces, causing the water to "flash" to steam. When this happens it expands exponentially - something like 1700:1 - blowing hot oil all over the place. This is bad enough on an enclosed element - it is EXTREMELY DANGEROUS when working with an open flame, as the splashing oil can easily ignite, and the possibility of igniting the whole pot of oil, although not terribly high, IS REAL. |

Ignoramus17069 fired this volley in
: No, it will not. And no, you have not done what Karl wants to do. i Actually, it can, Ig. It depends upon how you apply the heat. We had to dry out about 20lb of wet paraffin wax at the factory. I _almost_ had an injurious accident. I was melting the wax/water over an electric burner at high heat. It began to foam and boil vigorously, and didn't look _too_ likely to boil over-- it was just foaming to beat the band. I got called back to the office, and thought, "Well, I better turn the burner down so it won't catch fire while I'm away." I turned it down to a low heat, and began to walk away. I was about 30 feet away, when, at that point, all the tiny droplets of water suspended in hot wax settled to the bottom of the pot, then violently "BLURPED" out in one big surge. So long as the boiling was vigorous enough to keep the water off the bottom, it was fine. As soon as it settled out, it very nearly exploded. Keep in mind that there was enough of a column of wax over the water to at least slightly raise the boiling point. And then, when the water began to boil, it "relieved" its own pressure, which then left the water "superheated" for all intents and purposes. Even if it was only a tenth of a degree over its boiling point at our altitude, when it surged up, its boiling point dropped back to "normal", and thus it flashed to steam all at once. LLoyd |

And I'm a bit short right now. I'm wondering about putting it in a metal bucket on a hot plate out in the field. If you heat it to say 200, will it drive the water off? karl Got a vacuum pump? I doubt you have the volume to justify the sort of thing (as commercially and not cheaply built in Cortland, NY) we used on the transformer oil in the labs, but that was a vacuum-filtration I'm guessing vacuum pump oil costs more than whatever you dump into a tractor. You don't want water settling inside a vacuum pump either. |

It's an APPLE FARM, not a dairy. -- It's easy to think outside the box, when you have a cutting torch. |

If you heat it to say 200, will it drive the water off? karl Try a small ,say cup full first. It should work. then you will need to heat the larger amout in such a way as to not catch it on fire. Watch out. The oil floats, and when the water reaches boiling temperature, it pops up kind of explosively and hot oil sprays around. It's really dangerous. Yes, I have done it. No, it will not. And no, you have not done what Karl wants to do. i Ah, a challenge. g Ok, the single-burner Coleman is going now, under a 3-lb. steel coffee can with 1/4" of water and a half-quart of cheap motor oil...it's sounding like popcorn. POP! There it goes. 'Just sprayed oil all over the plywood scrap I use for mixing small batches of concrete. It better not be ruined, or I'll be annoyed -- at both of us. d8-) Try it, Iggy. Now, if you're going to say that Karl can control the temp to 200 F, my response is, good luck. But stand back. Try putting a 1 inch cube of meat on a fondue fork and plunge it into very hot oil... The water in the meat boils and causes it to spit oil like crazy ! These examples have NOTHING to do with heating oil to be near the boiling point of water. i |

Now, when you've settled down, you might want to go back and look at my original message, to which you objected, in which I said "watch out, don't let it boil." g Good for Karl. I'm glad it worked for him. -- Ed Huntress |

The other way definitely CAN be. |

And I'm a bit short right now. I'm wondering about putting it in a metal bucket on a hot plate out in the field. If you heat it to say 200, will it drive the water off? You can dry oil contaminated with water by heating it to about 90C/190F for several hours. I have done this on a large scale ( about 80,000 litres at a time) at my employers. I was Technical Superintendent of a lubricating oil manufacturing plant and after about 20 years the steam heating coils in the blending tanks fractured, releasing steam which condensed into water and emulsion as the oil was only heated to 60C. We simply transferred the oil to a sound tank, heated to 90C until the oil was dry. The test for water is called a "crackle test", simply put about 10 ml of oil in a test tube and heat with a bunsen burner or electric heater. If you hear popping sounds, the oil is still wet, continue drying until there is no popping. If you have a reasonably heavy gauge 60 litre steel drum with one or two bungs, fill it no more than about 2/3 full, then you can heat it safely until it is dry, the oil will not overflow and the water will evaporate through the bungs. Do not close the bungs. Do not use an open topped grease pail unless it is 180 kg size and filled with a maximum of 50 litres. Open containers are dangerous. You can use a 20 litre drum filled to about 15 litres but they are a thinner gauge steel and you have to be more careful with the heating method. I also have about 60 litres of damp transmission oil to dry from my tractor, will wait until the end of winter when the weather warms up a bit.
