Recycled Base Oil: An Eco-Friendly Lubricant Solution
Recycled Base Oil is a refined product obtained from used lubricating oils through advanced recycling and purification processes. It serves as a cost-effective and sustainable alternative to virgin base oils while maintaining high performance for various industrial and automotive applications.
Key Characteristics of Recycled Base Oil
- Viscosity Range: Available in different grades such as SN150, SN300, SN500, and SN600, catering to diverse lubricant needs.
- Color: Light to pale yellow, depending on the refining process.
- Flash Point: Typically above 190°C, ensuring good thermal stability.
- Pour Point: Generally between -9°C to -15°C, making it suitable for moderate and cold climates.
- Oxidation Stability: Enhanced through hydrotreatment or clay treatment to extend oil life.
- Low Impurities: Free from harmful contaminants like heavy metals and excessive sulfur.
Production Process of Recycled Base Oil
- Used Oil Collection & Pre-Treatment
– Waste lubricants are collected from automobiles, industries, and machinery.
– Initial filtration removes sludge, water, and large contaminants. - Dehydration
– The oil is heated to eliminate moisture and volatile compounds. - Distillation & Fractionation
– The oil undergoes vacuum distillation to separate different viscosity fractions. - Purification & Refining
– Hydrotreatment, clay treatment, or solvent extraction removes impurities and enhances oil quality. - Blending & Additive Treatment
– The refined base oil is blended with necessary additives for enhanced performance. - Quality Testing & Packaging
– The final product undergoes strict quality control checks before packaging and distribution.
Applications of Recycled Base Oil
- Automotive Lubricants – Used in engine oils, gear oils, and transmission fluids.
- Industrial Lubricants – Suitable for hydraulic oils, compressor oils, and metalworking fluids.
- Rubber & Tire Industry – Acts as a softening agent in rubber manufacturing.
- Transformer & Insulating Oils – Used in electrical applications requiring high purity.
