Cold process to recycle waste black oil

Is an advanced cold-process waste oil regeneration technology designed to convert dark, contaminated used lubricating oils into clean, reusable base oil without the use of heat, sulfuric acid, or other hazardous treatment methods. The process combines multi-stage chemical adsorption, solvent decontamination, and precision filtration to effectively remove sludge, carbon residues, oxidized compounds, emulsified water, and suspended contaminants. The result is a high-quality base oil with excellent color, stability, and performance suitable for reuse in a wide range of lubricant applications.
