Bio-Bunkering and Filtration: Enabling the Biofuel Revolution

Biofuel-Specific Filtration Challenges

• FAME: Hygroscopic nature increases water contamination risk → Phase separation and microbial growth 

• HVO: Low viscosity at cryogenic temperatures → Leakage in standard pumps 

• Bio-LNG: Cryogenic sediments (-162°C) clog fuel lines 

Filtration Solutions

1. Coalescer Filters:

   • Remove 95% free water from FAME blends using hydrophobic/hydrophilic media 

2. Svanehoj CS Fuel Pump:

   • Patented self-cleaning LNG filter prevents clogging in submerged bio-LNG pumps 

3. Thermal Stability Systems:

   • Preheat HVO to -40°C, paired with sintered metal filters (1-µm) for viscosity control 

Bio-Bunkering Hubs: Filtration Infrastructure

• Rotterdam: Uses B100-compatible filtration skids for 24/7 bio-bunkering 

• Singapore: B24 trials with ISO 21072-3-certified separators for high-viscosity biofuels 

Data Insight: Ships using filtered biofuels report 12% lower OPEX over 15 years due to reduced engine wear
