Oil recycling hi everyone my bum is itchy.....

the recycling of used oils and the creation of new products from the recycled oils. Oil recycling includes the recycling of Wikipedia:motor oil, hydraulic oil and Wikipedia:cooking oils. There are many environmental benefits in oil recycling: increased opportunities for consumers to recycle oil lessens the likelihood of used oil being dumped on lands and in waterways. For example, one Wikipedia:gallon of motor oil dumped into waterways has the potential to pollute one million gallons of water.[1]

Recycled motor oilEdit

Recycled motor oil can be combusted as fuel, usually in plant boilers, space heaters, or industrial heating applications such as blast furnaces and cement kilns. Recycled motor oil can be distilled into diesel or marine fuel in a process similar to oil re-refining, but without the final Wikipedia:hydrotreating process.

Used motor oil refiningEdit

Used oil re-refining is the process of restoring used oil to new oil by removing chemical impurities, heavy metals and dirt.[1] Used Industrial and automotive oil is recycled at re-refineries. The used oil is first tested to determine suitability for re-refining,and is first dehydrated in order to removes water, which is then treated before being released to the environment. Dehydrating also removes the residual light fuel that can be used to power the refinery, and additionally captures Wikipedia:ethylene glycol for re-use in recycled antifreeze.

Next, industrial fuel is separated out of the used oil then Wikipedia:vacuum distillation removes the lube cut (that is, the fraction suitable for reuse as lubricating oil) leaving a heavy oil that contains the used oil's additives and other by-products such as asphalt extender. The lube cut next undergoes hydro treating, or Wikipedia:catalytic hydrogenation to remove residual polymers and other chemical compounds, and saturate carbon chains with hydrogen for greater stability.

Final oil separation, or fractionating, separates the oil into three different oil grades: Light viscosity lubricants suitable for general lubricant applications, low viscosity lubricants for automotive and industrial applications, and high viscosity lubricants for heavy-duty applications. The oil that is produced in this step is referred to as re-refined base oil (RRBL).

The final step is blending additives into these three grades of oil products to produce final products with the right detergent and anti-friction qualities. Then each product is tested again for quality and purity before releasing it to the public for resale.[2][3][4]
