Pour Point Depressants (PPDs) & Wax Inhibitors
Ensuring Marine Fuels & Waxy Crudes Stay Pumpable in Cold Conditions
The Wax Challenge in Marine & Crude Fuels
When fuels containing paraffinic waxes cool below their Wax Appearance Temperature (WAT), wax crystals begin to form. Left untreated, they:
Grow and agglomerate into large structures
Cause gelling or solidification
Lead to filter plugging, pump starvation, and line blockages
Increase downtime and remediation costs
The issue has been amplified by:
IMO 2020 low sulphur fuel regulations → higher wax content in VLSFO and hybrid blends
Biodiesel blending in marine fuels → more unstable cold flow properties
Waxy crude oils in bunkering and transport → prone to deposition during shipping
Rodanco PPD & Wax Inhibitor Solutions
Rodanco’s advanced polymer based Pour Point Depressants (PPDs) and Wax Inhibitors are engineered to maintain fuel fluidity at low temperatures. These additives:
Co crystallize with wax during cooling
Modify crystal size and shape to prevent growth
Stop crystals from adhering to surfaces and blocking flow
Ensure fuels remain pumpable in winter or cold supply chains
These solutions are most effective when injected above the Wax Appearance Temperature (WAT) or Wax Dissolution Temperature (WDT), providing reliable protection against pour point failures and wax deposition risks.
Key Benefits
Pour Point Reduction
Keeps fuels fluid and pumpable (ASTM D97)
Viscosity Control
Reduces flow resistance in pipelines and storage
Wax Deposition Inhibition
Prevents wax build-up on cold surfaces
Operational Reliability
Smooth handling in cold ports, pipelines, and storage
Cost Efficiency
Minimizes expensive mechanical cleaning or thermal remediation
Core Features
High Performance Dispersion-Based PPDs
Advanced dispersions maintain high polymer activity while staying liquid and pumpable at very low temperatures, offering robust pour point and wax inhibition across marine fuels, hybrid blends, and biodiesel-rich systems
Solution Based PPDs
Proven polymer solutions for refinery and crude oil applications, providing pour point reduction, viscosity control, wax inhibition, and enhanced phase separation
Applications
Rodanco PPDs and Wax Inhibitors are trusted in:
Marine Fuels
VLSFO, residuals, hybrids, and bio-derived fuels; ensuring pumpability in cold ports and during long voyages
Bunkering Operations
Stabilizing waxy crudes and blended fuels for safe handling
Refineries & Blending Terminals
Achieving cold flow compliance (ASTM D97, CFPP, PP specifications)
Biofuel Integrated Marine Fuels
Countering wax instability from FAME and other bio-blends
Cold Climate Fuel Supply Chains
Preventing wax deposition in pipelines, storage tanks, and ship systems
Solution Based Pour Point Depressants (Conventional)
Proven polymer solutions for refinery and crude oil applications
Reliable performance in lowering pour points and improving flow
Effective for marine and distillate fuels
Provide viscosity reduction, wax inhibition, and separation control
Strong inhibitors of wax deposition in crude oils and heavy fuels
Generally less cold-stable compared to dispersion-based technologies
