The Challenge: Wax in Waxy & Paraffinic Crude Oils
Waxy and paraffinic crude oils are prone to wax precipitation when temperatures fall below the Wax Appearance Temperature (WAT). In cold subsea lines, long pipelines, or during unplanned shutdowns, wax crystals can form and grow; causing a chain of flow assurance problems:
Pipeline restart failures due to crude solidification
Throughput loss from wax deposition and flowline restriction
Higher pumping costs from increased viscosity and back pressure
Difficult oil/water separation, complicating downstream processing
Without a robust wax management strategy, these issues can lead to production losses, costly remediation campaigns, and safety risks.
Rodanco Comprehensive Wax Control Solutions: Ensuring Flow, Safety, and Reliability
Rodanco provides field-specific wax management programs combining pour point depressants, wax inhibitors, dispersants, and wax/asphaltene removers, supported by flow assurance expertise and custom laboratory testing. These solutions are designed to maintain steady production rates, prevent unplanned shutdowns, and ensure safe and reliable operation of pipelines and processing facilities.
Key Solution Areas & Benefits
1. Pour Point Depressants (PPDs) & Wax Inhibitors – Prevention
• Modify wax crystal size and shape to prevent adhesion to pipeline surfaces
• Lower pour point and reduce viscosity, keeping crude oil flowable
• Suitable for injection above wax appearance or wax dissolution temperatures
• Advantages include high polymer content, pumpability in extremely cold climates, and effective performance for subsea and cold environment operations
2. Wax Dispersants – Control & Stabilization
• Prevent agglomeration of existing wax crystals, keeping wax suspended in crude oil
• Reduce wax build-up, pigging frequency, and mechanical cleaning
• Improve oil/water separation and maintain steady flow rates
• Effective in wet production systems and adaptable across diverse crude types
3. Wax & Asphaltene Removers – Remediation
• Dissolve and mobilize existing wax or asphaltene deposits, especially after shutdowns or in cold climates
•Enable safe pipeline restart and minimize mechanical intervention
• Reduce downtime and operational disruption during cleaning or maintenance
• Compatible with hot water wash, circulation loops, and batch cleaning operations
