Implementing biodiesel distillation: choose the right path for your needs

Introduction — choose the implementation path that fits

Upgrading an existing unit or building new capacity? Sulzer offers flexible delivery with guaranteed performance. You can choose from Full ISBL, skid supply, or a customizable scope. Our testing facilities allow you to validate outcomes before you commit.

Integration options

Retrofit

You can insert distillation and, if necessary, adsorption into your existing line. This approach allows you to leverage current tanks and utilities while achieving winter-grade and ultra-low sulfur biodiesel.

Skid supply

Accelerate your deployment with pre-engineered skids. This option is ideal for meeting time-to-market demands and brownfield constraints.

Full ISBL

We provide end-to-end delivery, including methanol recovery, drying, glycerin refining, and FAME fractionation. Everything is engineered as one integrated train.

Typical scope of supply

• Biodiesel Distillation (+ post-distillation candle evaporator for high FAME yield)

• Adsorption Polishing for guaranteed <10 ppm sulfur (optional)

• Methanol Recovery with the highest recovery rate and purity from biodiesel and glycerin

• Biodiesel/Glycerin Separation, Biodiesel Washing, Biodiesel-Water Separation

• Biodiesel Drying, Glycerin Drying, Glycerin-Fatty Matter Separation

• Glycerin Refining to USP and Glycerin to Propylene Glycol (optional valorization)

• Static separation philosophy: no rotating separation equipment required

  
  

Performance, cost, and delivery

• Typical distilled biodiesel cost: USD 25–30/ton

• Adsorption treated cost: USD 28–33/ton

• Distilled biodiesel typical specs: monoglycerides ≤0.2 wt%, FFA ≤0.25 wt%, moisture <100 ppm, CSFT ≤300 s, sulfur <15 ppm

• Guaranteed <10 ppm sulfur with the adsorption add-on

• Reference plant in operation and a long reference list

• Testing facilities available to de-risk your decisions

  
  

Execution roadmap

1) Define targets

Identify your feed slate(s), winter-grade requirements, sulfur target (choose between <15 ppm and <10 ppm), and product handling specifics.

2) Test & validate

Run samples through our testing facilities to confirm performance, energy balance, and color improvement.

3) Engineer the scope

Select between ISBL, skid, or custom options. Align utilities, controls, and tie-ins. Confirm the static separation design to minimize maintenance.

4) Deliver & guarantee

We will manufacture, install, and performance test your system against the agreed guarantee.

FAQ — project delivery

Q1: How fast can we implement?

A: Timelines depend on the scope and permitting. Skids accelerate delivery, while ISBL provides full integration.

Q2: How do you guarantee performance?

A: We contract on specific product specs (e.g., <10 ppm sulfur with adsorption), yield, and operating parameters.

Q3: Do we need rotating equipment for separation?

A: No, our design employs static separation—no rotating separation equipment—which reduces maintenance needs.

Q4: Can you integrate our methanol and glycerin loops?

A: Yes, we ensure the highest methanol recovery rate and purity, along with glycerin refining to USP or glycerin to propylene glycol.

Q5: How do we ensure winter-grade performance?

A: Distillation effectively removes low-temperature precipitating fractions. We validate CFPP performance in our testing facilities.

Q6: Do you provide references?

A: Yes, we have a reference plant in operation and a long reference list available.

The importance of biodiesel distillation

Biodiesel distillation is crucial for producing high-quality fuel. It enhances the purity of biodiesel, ensuring compliance with stringent industry standards. The process also helps in removing impurities that can affect engine performance and emissions.

Benefits of high-quality biodiesel

High-quality biodiesel offers several advantages:

• Improved Engine Performance: Reduces engine wear and enhances fuel efficiency.

• Lower Emissions: Contributes to a cleaner environment by reducing harmful emissions.

• Regulatory Compliance: Meets the stringent requirements set by regulatory bodies.

  
  

Conclusion

Implementing biodiesel distillation is a strategic move for any operation in the chemical and petrochemical sectors. It not only enhances product quality but also aligns with the industry's shift toward low-carbon manufacturing.
