Introdução detalhada do processo
A detailed display of the main re-refining modules, matching product-level technical presentation needs for industrial buyers and investors.
The First Critical Step in Waste Oil Re-Refining
The pretreatment system is the first key stage in the waste oil to base oil process. Its function is to remove water, sludge, metallic particles and unstable contaminants from the raw feed, creating more stable conditions for downstream distillation and refining.
- Filtration: removes suspended solids and particles.
- Dehydration: lowers water content before thermal separation.
- Feed Stabilization: reduces fluctuation in raw material quality.
- Equipment Protection: helps reduce fouling, blockage and corrosion risks.
One of the Core Separation Technologies
Thin film distillation is one of the core separation technologies in the plant. Under controlled vacuum and temperature conditions, the feed forms a thin liquid film, enabling rapid evaporation and efficient separation while minimizing oxidation and thermal damage.
- High Heat Transfer Efficiency: improves evaporation and separation performance.
- Vacuum Operation: helps reduce thermal stress on recovered oil fractions.
- Short Residence Time: helps preserve valuable oil properties.
- Low Oxidation Risk: supports brighter and more stable base oil output.
- Continuous Processing: suitable for industrial production.
Precise Recovery of Different Base Oil Fractions
The fractionation system allows separation of recovered oil streams according to boiling range, helping produce different base oil grades such as SN150, SN350 and SN500 with improved product consistency and resource utilization.
- Precise Fraction Split: improves control of target base oil ranges.
- Multi-Grade Output: supports production of several base oil classes.
- Better Product Consistency: improves stability for downstream blending use.
- Higher Resource Utilization: increases value recovery from waste oil.
Improving Color, Sulfur and Stability of Base Oil
Solvent extraction refining is an important deep-treatment stage for premium base oil production. It helps remove aromatics, sulfur-containing compounds and unstable materials, improving clarity, oxidation resistance and product value.
- Color Improvement: supports brighter and cleaner finished oil.
- Sulfur Reduction: improves suitability for higher-grade targets.
- Acid Value Control: helps achieve more stable quality results.
- Higher Product Value: supports stronger commercial marketability.
Final Polishing for High-Grade Base Oil Production
Adsorption finishing uses activated clay or molecular sieve media for final purification. It serves as a polishing step to improve appearance, reduce trace impurities and enhance the final market acceptance of regenerated base oil.
- Final Clarification: improves visual brightness and transparency.
- Trace Impurity Removal: helps reduce residual polar compounds.
- Flexible Process Combination: can work together with solvent extraction.
- Market-Oriented Output: supports premium finished base oil positioning.
