Integrated Urea Storage Solutions
We provide more than just storage; we deliver fully integrated flow control solutions engineered for temperature stability, purity maintenance, and operational longevity.
I. Specialized Vessel Construction
- Primary Materials: Tanks are primarily constructed from 316L Stainless Steel for superior resistance to the mildly corrosive nature of urea. For smaller applications, High-Density Cross-Linked Polyethylene (XLPE) with UV inhibitors is available.
- ASME Compliance: All vessels meet the latest edition of ASME Section VIII, Division 1 for Unfired Pressure Vessels.
- Structural Stability: Features heavy-duty saddles and reinforced foundations to ensure the long-term integrity of the installation.
II. Thermal Management & Stability
- Freezing Protection: Essential for urea concentrations (typically 32.5% to 50%).
- 32.5% (DEF): Crystallizes at ~31°F.
- 50% Industrial Urea: Requires a minimum maintained temperature of 80°F to prevent "creeping" crystallization.
- Insulation: Minimum 2-inch closed-cell polyisocyanurate or mineral wool with a weatherproof aluminum or stainless steel jacket.
- Heat Tracing: Self-regulating electric heat trace cables to prevent "salting out."
- Hydrolysis Prevention: Integrated High-Temperature Alarms and automated cut-offs prevent urea from decomposing into ammonia and CO2 (which begins at temperatures above 110°F).
III. Advanced Digital Instrumentation
- Level Sensing: Non-contact ultrasonic or radar transmitters preferred to avoid "urea scale" buildup.
- Temperature Monitoring: Redundant RTDs (bottom and mid-tank) integrated into the PLC to manage precise heating cycles.
- Dosing Supply: Submerged suction lances ensure a constant supply of liquid to dosing skids.
IV. Redundant Safety & Mitigation Layers
- Pressure Management: Conservation vents and manways designed for easy inspection and periodic cleaning of solids.
- Seal Integrity: Utilization of EPDM or PTFE gaskets (avoiding Viton which can degrade in urea).
- Emergency Protection: Integrated systems ensure safe off-gassing management and overflow prevention.
