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:
- Dehydration: This step aims to eliminate water and moisture content from the used oil.
- Heating: Light fractions are removed through heating.
- Solvent Extraction: Contaminants are extracted using solvents.
- 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.
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.
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.
