This blog delves into the detailed production process of Base Oil SN 500, its numerous uses, applications, advantages, and disadvantages. Additionally, we highlight why Peak Universal Business is the preferred supplier of high-quality Base Oil SN 500.

Understanding Base Oil SN 500

Base Oil SN 500 is a Group I base oil with a viscosity of approximately 500 SUS (Say bolt Universal Seconds) at 100°F. It is derived from the refining of crude oil and is widely used in the production of lubricants. Group I base oils are known for their solvent extraction and dewaxing processes, providing good performance characteristics for a range of applications.

Production Process of Base Oil SN 500

The production of Base Oil SN 500 involves several key steps, each critical to achieving the desired quality and performance characteristics. The process generally includes the following stages:

1. Crude Oil Distillation

The production begins with the distillation of crude oil in a refinery. This process separates the crude oil into various fractions based on their boiling points. The fraction suitable for base oil production is further processed to remove impurities and unwanted components.

  • Atmospheric Distillation

In this initial distillation stage, crude oil is heated in a distillation column. The lighter fractions (such as gasoline and kerosene) are separated from the heavier fractions. The heavier fractions, often referred to as vacuum gas oil, are directed to the next stage of processing.

  • Vacuum Distillation

To further refine the heavier fractions, vacuum distillation is employed. This process operates at lower pressures, allowing the separation of components at lower temperatures, which helps preserve the quality of the base oil. The desired fraction for Base Oil SN 500 is collected and sent for further treatment.

2. Solvent Extraction

Solvent extraction is used to remove undesirable components such as aromatic hydrocarbons, which can negatively affect the performance of the base oil. This process enhances the oil’s stability and improves its viscosity index.

  • Furfural Extraction

One common method is furfural extraction, where furfural (a solvent) is mixed with the base oil fraction. Aromatics and other impurities dissolve in the furfural and are separated from the desired paraffinic hydrocarbons. The paraffinic-rich phase is then distilled to recover the solvent, leaving behind a purer base oil.

3. Dewaxing

The dewaxing process removes waxy components that can cause the oil to solidify at lower temperatures, ensuring that the base oil remains fluid under various conditions.

  • Solvent Dewaxing

In solvent dewaxing, the base oil is mixed with a solvent (typically a mixture of toluene and methyl ethyl ketone) and cooled. Waxes crystallize out and are removed by filtration. The remaining oil-solvent mixture is then heated to recover the solvent, leaving behind dewaxed base oil.

4. Hydro finishing

Hydro finishing is a hydrogenation process that further refines the base oil to improve its color, stability, and performance. This step ensures that the base oil meets stringent quality standards.

  • Hydrogen Treatment

The base oil is treated with hydrogen in the presence of a catalyst. This process saturates any remaining unsaturated hydrocarbons, removes sulfur and nitrogen compounds, and enhances the overall purity and performance of the base oil.
