The Process of Re-Refining Used Oil
- Collection & Pre-Treatment – Used oil is collected from vehicles, industrial machinery, and other sources. It is then filtered to remove water, solids, and contaminants.
- Dehydration & Distillation – The oil undergoes dehydration to eliminate moisture, followed by vacuum distillation to separate lighter hydrocarbons.
- Hydrotreating & Purification – Hydrogenation or clay treatment removes impurities, sulfur, and other unwanted compounds, restoring the oil’s chemical stability and performance.
- Blending & Additives – The refined base oil can be blended with performance additives to match the quality of virgin base oils used in lubricants.
Advantages of Re-Refining Used Oil
- Environmental Benefits – Reduces hazardous waste, lowers carbon emissions, and prevents oil pollution.
- Resource Efficiency – Extends the lifecycle of oil, minimizing the need for virgin crude oil extraction.
- Cost Savings – Provides a more cost-effective and energy-efficient alternative to refining new oil.
- Regulatory Compliance – Supports industries in meeting environmental regulations and sustainability goals.
