Detailed Process Introduction
A more detailed display of the main process modules, matching product-level technical presentation needs for industrial buyers.
01 / Pretreatment System
The First Critical Step in Waste Oil to Diesel Processing
The pretreatment system is the first key stage in the waste oil to diesel process. Its function is to remove water, impurities and unstable components from the raw feed, providing more stable and controllable conditions for downstream distillation and refining.
- Impurity Removal: removes solid particles and metallic contaminants.
- Dehydration: reduces water content to a safer operating range.
- Feedstock Stabilization: minimizes raw material fluctuation.
- Equipment Protection: helps reduce coking, blockage and corrosion risks.
02 / Thin Film Distillation
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 component separation with shorter residence time.
- High Heat Transfer Efficiency: improves thermal exchange performance.
- Low-Temperature Operation: vacuum reduces thermal stress on products.
- Short Residence Time: helps minimize cracking and oxidation.
- Continuous Processing: supports stable industrial production.
- Anti-Coking Design: lowers carbon deposition risk.
03 / Fractionation System
Precise Separation of Different Boiling Point Fractions
The fractionation system is a key separation unit in the waste oil to diesel process. By separating components according to boiling range, it allows graded recovery of light oil, diesel fractions and heavier streams, improving product consistency.
- Improved Diesel Quality: controls fraction range for cleaner diesel.
- Multi-Product Recovery: improves resource utilization.
- Reduced Downstream Load: lowers burden on later refining stages.
- Stable Production: supports continuous output consistency.
04 / Refining System
Enhancing Stability, Cleanliness and End-Use Performance
The refining system is the deep-treatment stage of the plant. It removes residual impurities and unstable components remaining after distillation, helping improve product cleanliness, storage behavior and practical fuel performance.
- Higher Product Quality: lowers impurity content.
- Improved Performance: supports cleaner combustion behavior.
- Longer Storage Life: helps reduce oxidation deterioration.
- Wider Market Adaptability: supports broader downstream applications.
05 / Oxidative Extraction Desulfurization
Deep Desulfurization for Higher Diesel Standards
Oxidative extraction desulfurization is an advanced deep-treatment process combining oxidation reaction and solvent extraction. Sulfur compounds are converted into more separable polar compounds and then removed more effectively.
- Highly Selective Desulfurization: effective for difficult sulfur compounds.
- Mild Operating Conditions: suitable for medium-low temperature treatment.
- Synergistic Process Design: oxidation and extraction work together.
- Solvent Recycling: helps reduce operating cost.

AdvantageHigher investment generally delivers higher total profit and stronger long-term competitiveness
Recommended Choice: The 10–50 T / Day Standard Plant is the most recommended configuration for most customers because it offers moderate investment, fast profit recovery and stable commercial output. At the same time, in this industry, larger capacity usually means higher total profit.
Balanced Investment
The 10–50 T / Day range is suitable for customers seeking a practical balance between capital input, output scale and business controllability.
Fast Profit Recovery
This model range is widely preferred because it can achieve stable output and relatively fast return under normal raw material supply conditions.
Bigger Scale, Higher Profit
For investors with stronger feedstock channels and market demand, larger-capacity plants usually generate higher total profit and stronger market expansion value.
