Re-Refining

With time and distance travelled, passenger car motor oils (“PCMO’s) become dirty but the underlying base oils do not wear out. In fact, it is the additives package (i.e. dispersants, detergents, anti-oxidants, etc.) in the PCMO that breaks down, while additional contaminants (i.e. metal filings, etc.) are introduced from the engine. In order to maintain maximum engine efficiency, you need to replace your PCMO on a regular basis. The re-refining process is able to remove the spent additives and contaminants and return the base oil to its original state for blending into new PCMO formulations.

An estimated 2.64 billion gallons of motor oil are sold in North America each year, but it is estimated that less than 50% of that is collected for re-processing. This leaves the possibility that the uncollected oil can make its way into the environment and pollute natural resources. Furthermore, about 50% of UMO is used as a fuel for industrial burners. In addition to the environmental impacts of this practice, this represents the lowest value end use for used motor oil. Re-refining produces high quality end products that are indistinguishable from virgin crude products, while diverting a harmful waste stream and contributing to resource sustainability.

History of Re-refining

Oil re-refining has been around for decades, but it was the OPEC oil embargo in the 1970s that forced innovation in the sector. Before this time oil recycling technologies were not able to produce base oils that met the market’s quality standards. However, a tripling of crude prices incentivized technological development to meet the demand.

In the 1980’s hydrotreating was introduced to the industry in the form of the Phillips Re-refined Oil Process. This first commercial scale re-refining technology demonstrated the viability of hydrotreating and was used by other companies in their emerging used oil management facilities. As more companies entered the market they began to improve on the technology, incorporating another refining technology called vacuum distillation and making further process improvements, resulting in a process that became industry standard for three decades.

From 1991-2008 there were no new re-refining projects in North America. However, the oil boom following this period, combined with a shift towards higher quality lubricants has caused the industry to innovate once again, and ReGen III is leading the way with our breakthrough ReGen™ re-refining technology.

ReGen™ Technology

ReGen™ combines proven refining technologies into a proprietary process that is able to extract a higher quantity of high quality base lubricating oils than traditional re-refineries, including approximately 55% Group III base oil production.

Used motor oil will arrive at the ReGen III facility where it will go through a series of refining processes to remove contaminants and restore the base oils to their original state. As the UMO’s are processed, the highest quality base oils are separated from other petroleum by-products, such as ultra-low sulphur diesel.

The end result is Group III and Group II base oils that meet the American Petroleum Institute’s standards. These base stocks will be sold to bp and mixed with additives packages to create high quality finished PCMO’s.
