re refined base oil SN300

Base Oil SN300 is a Group I solvent neutral base oil, commonly utilized in the production of lubricants and lubricant additives. It is derived from mineral crude oil through processes such as solvent refining, dewaxing, and hydrogen treatment, ensuring its purity and performance.

Physical and Chemical Properties

These properties make SN300 suitable for various lubricant applications, providing a balance between viscosity, thermal stability, and fluidity under different temperature conditions.

Production Process

The production of Base Oil SN300 involves several key steps:

• Vacuum Distillation: Used oil undergoes vacuum distillation to separate it into different fractions based on boiling points. This process removes water and light hydrocarbons, yielding a heavier fraction suitable for base oil production.
• Hydrotreating: The distilled oil is treated with hydrogen to remove impurities such as sulfur, nitrogen, and oxygen compounds. This step enhances the oil’s stability, color, and odor, resulting in a high-quality base oil.
• Solvent Refining and Dewaxing: Further refining processes, including solvent extraction and dewaxing, are employed to improve the oil’s viscosity index and low-temperature properties. These steps ensure the base oil meets the desired specifications for lubricant formulations.

Applications

Base Oil SN300 is widely used in the formulation of:

• Automotive Lubricants: It serves as a primary component in engine oils, transmission fluids, and gear oils, providing essential lubrication and protection for vehicle components.
• Industrial Lubricants: SN300 is utilized in hydraulic fluids, compressor oils, and other industrial lubricants, ensuring efficient operation of machinery and equipment.
• Process Oils: It is employed in the manufacturing of rubber, plastics, and other materials as a processing aid, enhancing the properties of the final products.

Environmental Considerations

The re-refining process of used oils into base oils like SN300 contributes to environmental sustainability by:

• Resource Conservation: Recycling used oil reduces the demand for virgin crude oil, conserving natural resources.
• Waste Reduction: Proper re-refining prevents the improper disposal of used oils, which can contaminate soil and water sources.
• Energy Efficiency: Re-refining used oil consumes less energy compared to producing base oil from virgin crude, lowering the overall environmental impact.

Quality Assurance

To ensure the high quality of Base Oil SN300, manufacturers adhere to standardized test methods such as ASTM D-445 for kinematic viscosity, ASTM D-92 for flash point, ASTM D-97 for pour point, and ASTM D-1298 for density measurements. These standardized tests guarantee that the base oil meets industry specifications and performance requirements.

In summary, Base Oil SN300 is a versatile and essential component in the lubricant industry, offering a balance of desirable properties for various applications. Its production through re-refining processes underscores the industry’s commitment to sustainability and environmental responsibility.
