Re-refined Base Oils

Re-refined Base Oils

Re-refined base oils find application across various industries, including automotive, industrial and other usages. In the automotive sector, they serve as an eco-friendly alternative for lubricating engines, gears, and hydraulic systems. Manufacturers often incorporate re-refined (recycled) oils into their processes to reduce costs and enhance sustainability.

In the pursuit of sustainable practices and environmental consciousness, industries are constantly seeking innovative solutions to reduce their carbon footprint and minimize waste. One such solution gaining traction is the utilization of re-refined oils. These oils offer a promising avenue for businesses to not only meet their operational needs but also contribute positively to the environment. Let’s delve into the intricacies of recycled oils: their usage, stages of production, and types available.

The commonly method for producing Re-Refined Base Oil (RRBO) involves solvent extraction. In this approach, several sequential steps are typically followed:

  1. Dehydration: This step aims to eliminate water and moisture content from the used oil.
  2. Heating: Light fractions are removed through heating.
  3. Solvent Extraction: Contaminants are extracted using solvents.
  4. Hydro-treatment: This step facilitates a molecular conversion process.

FAQ Re-refined and Re-generated Base Oils

Re-generated (recycled) base oils are oils that have been processed to remove impurities and contaminants, making them suitable for reuse in various industrial applications.

Re-generated base oils offer a cost-effective and environmentally friendly alternative to virgin base oils. By reusing oils, you contribute to resource conservation and waste reduction.

Price: re-refined base oils are usually priced cheaper versus similar quality virgin base oils which gives economical benefits to the lube blender. Regenerated base oils could be used in the most cost competitive applications due to it low prices.

Environmental Impact: Opting for regeneration significantly reduces the greenhouse effect and the emission of CO₂. Unlike renewable energy sources, oil is finite, and regeneration extends the lifespan of this scarce natural resource. Re-generated oil production generated about 5 times less CO₂ vs similar virgin base oils according to one US leading re-refined base oils producers.

Sustainability: Used oil can undergo regeneration indefinitely, whereas burning or utilization of it after a single use is not sustainable. By choosing regeneration, we contribute to the conservation of resources for future generations.

Global Benefit: Regeneration is particularly beneficial for regions without access to their own oil sources. It provides a sustainable solution that reduces reliance on external oil supplies, cut delivery period and excessive transport emissions.

Energy Efficiency: Compared to obtaining fresh oil through traditional refining processes, regeneration consumes approximately two-thirds less energy. This significant reduction in energy consumption contributes to overall energy efficiency and conservation efforts.

Quality Assurance: Recycled base oils maintain at least the same quality standards as first-refined oils. Through advanced regeneration processes, the integrity and performance of the oil are preserved, ensuring reliability in various applications.

Compatibility: Recycled oils can be seamlessly mixed with first-refined oils in any proportion without compromising quality specifications. This flexibility enhances the versatility of regenerated oils, allowing for their widespread use across industries.

There’s a growing interest in re-refined base oils (RRBOs) paralleling the global emphasis on recycling, minimizing carbon footprints, and safeguarding the environment. Rather than discarding waste oils, more producers are adopting practices to collect these used oils and employ advanced technological processes like vacuum distillation, hydrotreating, clay treatment, and solvent extraction to eliminate impurities.
The environmental advantages of products utilizing RRBOs are substantial compared to conventional lubricants derived from virgin base oils. Research indicates a noteworthy reduction in carbon dioxide (CO2) emissions by 20% to 40% when compared to products originating from virgin oils. Moreover, this process effectively addresses concerns surrounding the disposal of spent lubricants, offering a sustainable solution to manage waste and minimize environmental impact.

Re-refined base oils (RRBOs) is another name for recycled or re-generated base oils. RRBOs are increasingly favored as the focus on recycling, shrinking carbon footprints, and environmental conservation intensifies. Rather than simply disposing of used oils, an increasing number of producers are opting to collect them and subject them to advanced technological treatments like vacuum distillation, hydrotreating, clay treatment, and solvent extraction. These processes effectively eliminate impurities from the used oils, elevating the quality of RRBOs and overcoming previous challenges such as differences in color and noticeable odors.

Although the rates of oil collection and regeneration differ across regions, there’s a notable expansion in the volume of used oil being collected and re-refined worldwide. The global market for Re-refined Base Oils (RRBOs) was valued at USD 6.4 billion in 2021, and forecasts suggest that it will surge to USD 8.8 billion by 2027, with a c growth rate of 6.5%. Particularly, the Asia-Pacific region is anticipated to emerge as the swiftest-growing market for RRBOs. USA and Europe are the markets with biggest penetration of re-refined base oils.

Re-generated base oils come in various grades and qualities, ranging from standard to premium. The price may vary depending on the purity, viscosity, and other specifications of the oil. The price of re-generated base oils is also influenced by factors such as volume and delivery location. Usually re-refined base oils are trading at a discount to virgin base oils with similar quiality properties. To get an accurate quote please contact us via Get a Quote form.

Regenerated base oils are usually available in light grades between SN60 and SN150, rare viscosity can go up to SN200, SN300 and SN400 and very rarely can reach SN500. Most of quantity is usually produced between viscosity 4 and 6 cSt @ 100C which is equivalent to SN100 and SN150 grades.

Re-generated base oils can be Group I, Group II or Group III depending on the refining process. Some refineries are flexible to switch between Group I and group II when they see more demand or better margin in one of the groups.

Group I re-cycled base oil can be different in terms of colour, smell, sulphur content and pour point compared to virgin base oils. In lower quality re-refined based oils mechanical admixtures could be found. Regenerated base oils can also oxidate faster, that should be taken into consideration during storing of the product.

Group II and Group III re-refined base oils are very similar quality of virgin base oils.
