Propane Mounded Vessels are specialized tanks designed for the safe and efficient storage of propane and other liquefied petroleum gases (LPG) while being buried under a protective mound of earth. This design offers enhanced safety, insulation, and environmental protection. Key Specifications: 1. Design & Construction: • Shape: Typically horizontal cylindrical or bullet-shaped to optimize space and storage capacity. • Material: o Constructed from high-grade carbon steel or stainless steel, compliant with ASME Section VIII, API 620, or equivalent standards. o External coating and cathodic protection to resist corrosion. • Capacity: o Ranges from 10,000 to 500,000 liters, with custom sizes available based on specific requirements. • Pressure Rating: Designed to handle pressures up to 400 psi (27.5 bar) or higher, depending on operational needs. 2. Mounded Installation: • Mounding: o Tanks are buried under a mound of earth or sand, providing natural insulation and additional protection. o The mound helps protect the vessel from external environmental conditions and fire risks. • Protection: o The mounding provides thermal insulation, reducing the risk of temperature fluctuations. o Helps in reducing the risk of mechanical damage and environmental impacts. 3. Safety Features: • Pressure Relief Valves: Essential for managing overpressure and ensuring safe operation. • Leak Detection Systems: Integrated electronic sensors for early detection of leaks. • Emergency Shutoff Valves: Allows immediate isolation of the tank in case of emergency. • Fire Protection: o Optional fire suppression systems including water spray or foam. o Mounding acts as a fire barrier to protect the tank from direct flames. 4. Piping and Connections: • Piping Material: High-quality steel or stainless steel designed to handle high-pressure propane. • Connections: o Includes standard flanged or threaded connections for easy integration. o Features shutoff valves, filters, and strainers as required for safe operation. 5. Instrumentation and Controls: • Level Gauges: Both visual and electronic gauges for accurate measurement of propane levels. • Pressure and Temperature Sensors: Real-time monitoring for pressure and temperature inside the vessel. • Control Panel: Centralized control panel for managing operations, with options for remote monitoring and control. 6. Environmental and Compliance: • Vapor Recovery Systems: Optional systems to capture and recycle propane vapors, minimizing environmental impact. • Secondary Containment: Integrated spill containment to prevent environmental contamination. • Compliance: Meets industry standards including ASME, NFPA 58, and local safety regulations. 7. Applications: • Industrial Storage: Ideal for large-scale industrial facilities requiring bulk propane storage. • Commercial Use: Suitable for commercial facilities with significant propane storage needs. • Utility Storage: Provides safe and efficient storage for utilities and energy providers. Benefits: • Enhanced Safety: Mounding offers superior protection against environmental and operational risks, including fire and mechanical damage. • Operational Efficiency: Natural insulation reduces the need for additional temperature control systems. • Durability: Built to withstand high pressure and harsh environmental conditions with minimal maintenance. • Environmental Protection: Mounding minimizes environmental impact and protects against soil and groundwater contamination.
