The Production Roadmap

Our 8-step quality assurance process transforms raw feedstock into international standard Biodiesel.

01. Virgin Oil Drying

Removing moisture content to prevent soap formation during reaction.

Our Innovations

Our vacuum drying systems reduce moisture content to <0.05%, critical for preventing catalyst neutralization. We utilize high-efficiency heat exchangers to preheat the oil, minimizing overall energy consumption.

02. Transesterification

The core chemical reaction converting oils into fatty acid methyl esters (Biodiesel).

Our Innovations

We employ a proprietary continuous reactor design ensuring 98%+ conversion efficiency. Optimized residence time and mixing intensity allow for lower catalyst usage while maintaining high yield.

03. Biodiesel Washing

Removing residual catalyst, soap, and methanol impurities.

Our Innovations

Our advanced counter-current washing columns remove trace impurities with minimal water usage. This system ensures rigorous ASTM D6751 compliance for soap and catalyst residue limits.

04. Biodiesel Drying

Final moisture removal to ensure fuel stability and efficiency.

Our Innovations

Using a final vacuum flash drying stage, we remove all traces of water. This step is crucial for long-term fuel stability and preventing microbial growth during storage.

05. Cold Flow & Bleaching

Improving cold weather performance and visual clarity of the fuel.

Our Innovations

Our integrated winterization process significantly improves the Cold Filter Plugging Point (CFPP). Additionally, our bleaching earth filtration system ensures crystal clear visual appearance.

06. Glycerol Purification

Separating the byproduct glycerol for secondary value streams.

Our Innovations

Through acidulation and neutralization, we recover free fatty acids and salts. We achieve 80-85% crude glycerol purity, making it a valuable byproduct for industrial applications.

07. Glycerol Concentration

Increasing purity levels for industrial grade applications.

Our Innovations

Our multi-stage evaporation systems concentrate glycerol to 99% technical grade. Energy integration with the main plant significantly reduces operating costs.

08. Methanol Rectification

Recovering excess methanol for reuse, ensuring process economy.

Our Innovations

High-efficiency distillation columns recover >99.9% pure methanol from both biodiesel and glycerol streams. This closed-loop system minimizes solvent loss and operating costs.
