re refined base oil SN350

Base Oil SN350 is a high-quality Group I base oil, commonly utilized in the formulation of various lubricants and lubricant additives. Derived from the solvent refining and dewaxing of crude oil, SN350 exhibits properties that make it suitable for a wide range of industrial and automotive applications.

Physical and Chemical Properties

These properties indicate that SN350 has a moderate viscosity, a high flash point, and a low pour point, making it versatile for various lubricant formulations.

Production Process

Base Oil SN350 is produced through a series of refining processes:

• Solvent Refining: This step removes undesirable components such as aromatics and sulfur compounds, enhancing the oil’s stability and performance.
• Dewaxing: Dewaxing improves the oil’s low-temperature properties by eliminating waxes that can solidify at lower temperatures.
• Hydrotreating: This process further purifies the oil by saturating hydrocarbons, resulting in improved oxidation stability and color.

These refining steps ensure that SN350 meets stringent quality standards required for lubricant base stocks.

Applications

Due to its balanced properties, Base Oil SN350 is widely used in the production of:

• Automotive Lubricants: Including engine oils and transmission fluids, where its viscosity and stability contribute to efficient engine performance.
• Industrial Lubricants: Such as hydraulic fluids, gear oils, and compressor oils, benefiting from its lubricating properties to reduce friction and wear.
• Metalworking Fluids: Serving as a base for cutting oils and grinding fluids, aiding in metal fabrication processes.
• Transformer Oils: Utilized in electrical transformers for insulation and cooling purposes.
• Marine Lubricants: Applied in marine engines and machinery, providing protection against corrosion and wear in marine environments.

Re-refining and Environmental Considerations

The re-refining of used lubricating oils into base oils like SN350 is an environmentally friendly practice that conserves resources and reduces waste. Processes such as vacuum distillation and thin film evaporation are employed to remove contaminants and recover valuable base oil fractions from used oils. This approach not only produces high-quality base oils but also minimizes environmental impact by recycling used lubricants.

Conclusion

Base Oil SN350 is a versatile and reliable component in lubricant formulations, offering properties that meet the demands of various industrial and automotive applications. Its production through advanced refining techniques ensures high quality and performance, while re-refining practices contribute to environmental sustainability.
