Base Oil Vacuum Distillation Machine From Used oil
A lubricating oil becomes unfit for further use for two main reasons: accumulation of contaminants in the oil and chemical changes in the oil. The main contaminants are listed Below.
1.Water. Fuel burns to CO2 and H2O. For every liter of fuel burnt, a liter of water is created. This normally passes out through the exhaust when the engine is hot, but when cold it can run down and collect in the oil. This leads to sludge formation and rust.
2.Soot and carbon.These make the oil go black. They form as the result of incomplete combustion, especially during warm-up with a rich mixtureLead. Tetraethyl lead, which used to be used as an anti-knock agent in petrol, passes into the oil. A typical used engine oil may have contained up to 2% lead, but today any lead comes from bearing wear and is likely to be in the 2 - 12 ppm range.
3.Fuel. Unburnt gasoline or diesel can pass into the lubricant, again especially during start-up.
4.Abrasives Road dust.This passes into the engine through the air-cleaner. Composed of mall particles of silicates. Wear metals. Iron, copper and aluminium released due to normal engine wear.
5.Chemical products.Oxidation products.Some of the oil molecules, at elevated temperatures, will oxidise to form complex and corrosive organic acids. Depleted additive remnants
