When oil is saturated with water, it will appear milky or foggy. Removing water from used motor oil can be done in a number of ways. Recycling plants will remove water and other impurities from oil. Chemicals are used during this process. Water can also be removed from motor oil in a simple way without the use of any chemicals. - Water can be removed from oil by recycling machines.Clean water and water bubbles in blue image by Suto Norbert from Fotolia.com
Oil recycling machines act to remove water along with other impurities from used oil. They use dehydration systems along with filtration and demulsifying techniques. Chemicals used in these machines include tetraethylene pentamine (TEPA), activated white clay and water glass, otherwise known as sodium silicate. - A filter can extract water from oil.water splash - bottle and water in a moment image by Stasys Eidiejus from Fotolia.com
A filter cartridge with an outer layer of polymer and desiccants will absorb the water from the oil, which can then be removed. The cartridge will remove emulsified water as well as free water. - Additive packages can be used with motor oil to purify it.motor image by Petr Efremov from Fotolia.com
Additive packages can be added to motor oil to aid purification although they are primarily for removing foreign chemicals and acids. They include detergents, buffers such as calcium or magnesium, solvents, lubricants such as zinc or phosphorous, and chemicals to improve viscosity. Corrosion inhibitors will stop oil from oxidizing. - Water and oil can separate.water drop is falling down and impact with water surface image by Alexander Potapov from Fotolia.com
When motor oil is left in a tank the water will settle to the bottom. This can then be removed by opening up a drain valve. However the oil may need to be left to settle for some time, depending on its characteristics and temperature.
