WASTE MINERAL OIL

General definition of oil: it is called lubricant or oil is used to
move material simply because of decreasing the friction power between two solid material.
Oils are classified two groups by production ways.
1.    Synthetic oil
2.    Mineral oil

Synthetic oil: Synthetic oil is oil consisting of chemical compounds which were not originally present in crude oil (petroleum), but were artificially made (synthesized) from other compounds. Where mineral oil is not used, synthetic oil is used into place instead of the oil. 
Mineral oil: Mineral oil or liquid petrolatum is a by-product in the distillation of petroleum to produce gasoline.

 Waste oil: The definition of waste oil or used oil is used oil of vehicles  and used oil in industry.Used oil is any oil that has been refined from  crude oil or any synthetic oil that has been used and as a result of  such use is contaminated by physical or chemical impurities..                                                                       

The statute of waste oil control  has become valid on 21.01.2004 at official gazette. It is forbidden with the statute to spilling waste oil into environment and burning waste oil.

 Oil through use or handling, has become unsuitable for its original purpose due to the presence of impurities or loss of original properties. 

 During normal use, impurities  such as dirt, metal scrapings, water, or chemicals can get mixed in with the oil, 

 so that in time the oil no longer performs well. Eventually, this used oil must be replaced with  virgin or re-refined oil.

 Why is waste oil hazardous?

 Waste oil is ecotoxic. It pollutes environment. Therefore, it should not be spilled into environment.

 It is forbidden burning waste oil because of including heavy metal. When it is burned, its smoke  harms  every liveliness.

 One liter waste oil pollutes one million liters water.

 How is Used Oil recycled?

Once oil has been used, it can be collected, recycled, and used over and over again.

Generally, the definition of recycling is a reprocess of used oil into re-use oil. The first category waste oil can be recycled with regeneration and re-refinery.

   * Regeneration, which involves removing impurities from the used oil and using it again.

   * Re-refinery, which involves treating used oil to remove impurities so that it can be used as a base stock for new lubricating oil. Re-refining prolongs the life of the oil resource indefinitely. The waste oil is recycled with distillation and acid-clay refinery process. The distillation process include to collapse, heating, vacuum, filtration and centrifugal. Big particles in waste oil are collapsed in collapse tank. After that, the oil is heated; water and volatile hydrocarbons are removed by vacuum.
