REFRIGERATED LPG STORAGE TANK DESIGN SERVICES

Refrigerated LPG (liquefied petroleum gas) storage tanks are critical components in industries like oil and gas, refineries, and pharmaceuticals where safe and efficient storage of liquefied gases is essential. Here’s an overview of their design, types, parts, and applications:

Types of Refrigerated LPG Storage Tanks

1. Horizontal Tanks: Typically used for smaller capacities and are easier to transport.

2. Vertical Tanks: Commonly used for larger capacities and can be more space-efficient.

Design Considerations

• Insulation: Essential to maintain the low temperature required to keep LPG in its liquid state.

• Safety Features: Pressure relief valves, emergency venting systems, and leak detection mechanisms are critical.

• Materials: Tanks are usually made of materials like carbon steel or stainless steel, chosen based on factors like corrosion resistance and strength.

Parts of Refrigerated LPG Storage Tanks

1. Inner Vessel: Holds the liquefied gas.

2. Outer Shell: Provides structural support and houses insulation materials.

3. Insulation: Various types like perlite, foam glass, or polyurethane foam are used to minimize heat transfer.

4. Safety Systems: Pressure relief valves, temperature sensors, and alarms ensure safe operation.

Manufacturing and Prices

• Manufacturing: Tanks are fabricated under stringent standards (e.g., API 620) to ensure safety and durability.

• Prices: Can vary significantly based on size, materials, and additional features. Prices are typically obtained through specialized suppliers or manufacturers.

Applications

• Oil and Gas Industry: Primary use for storing LPG before distribution or further processing.

• Refineries: Integral for managing by-products of refining processes.

• Pharmaceutical Industry: Used for storing gases in production processes where precise control and safety are paramount.

Associations and Standards

• API (American Petroleum Institute): Provides standards like API 620 for design and construction of large, welded, low-pressure storage tanks.

• NFPA (National Fire Protection Association): Provides guidelines for safe storage and handling of flammable liquids and gases.

Conclusion

Refrigerated LPG storage tanks play a crucial role in various industries by ensuring safe storage and distribution of liquefied gases. Their design, construction, and operation adhere to strict standards to mitigate risks associated with handling volatile substances. Prices and specifications vary widely, depending on capacity, materials, and regulatory compliance, making them specialized assets in industrial operations worldwide.
