Base Oil SN-150 is one of the most widely used mineral base oils within Group I, produced through solvent refining and hydrotreating processes. With its medium viscosity, stable thermal behavior, clean appearance, and excellent blending compatibility, SN-150 serves as a core component in the formulation of a broad range of lubricants, including engine oils, industrial lubricants, greases, and process oils. Owing to its balance of performance and affordability, Base Oil SN-150 remains an essential material for lubricant manufacturers worldwide.

This product is derived from vacuum-distilled petroleum fractions and further refined to remove aromatics, sulfur compounds, and other impurities. The result is a stable, clear, and well-balanced base oil suitable for numerous industrial applications requiring durability, oxidation control, and consistent viscosity.

Production Process of Base Oil SN-150

Base Oil SN-150 is manufactured through several refining steps that ensure purity, stability, and optimal performance:

1. Atmospheric and Vacuum Distillation

Crude oil is first distilled under atmospheric pressure and then under vacuum to isolate the heavy fractions used for base oil production.

2. Solvent Extraction

Aromatic compounds, nitrogen-containing molecules, and unstable hydrocarbons are removed using solvents such as phenol or furfural.

3. Dewaxing

This step eliminates long-chain paraffins to improve the pour point, enhancing low-temperature fluidity.

4. Hydrotreating

Hydrogen treatment improves color, odor, oxidative stability, and overall performance of the base oil by saturating unstable hydrocarbons.

5. Final Filtration and Polishing

The final purification stage ensures clarity, stability, and contaminant-free product ready for blending or bulk shipment.
