Processed Natural Gas Storage Tanks

Natural gas storage tanks are specialized containers used to store compressed natural gas (CNG) or liquefied natural gas (LNG). They are designed to withstand high pressure or low temperatures and are commonly used in industrial, energy, or residential applications to ensure the safe storage and supply of natural gas.

Types

1. Compressed Natural Gas (CNG) Storage Tanks:
   • Store compressed natural gas at high pressure (typically 200-250 bar).
   • Typically cylindrical or spherical, manufactured from high-strength materials (such as steel or composite materials).
   • Used for natural gas vehicles (NGV), industrial gas supply, or small storage facilities.
2. Liquefied Natural Gas (LNG) Storage Tanks:
   • Store liquefied natural gas at low temperatures (approximately -162°C).
   • Employ a double-walled vacuum insulated design to maintain low temperatures.
   • Commonly used in large storage facilities, transport ships, or receiving terminals.
3. Underground Storage Facilities:
   • Facilities for large-scale storage of natural gas, such as abandoned salt caverns, underground gas fields, or aquifers.
   • Used to regulate seasonal supply and demand or for strategic reserves.

Key Features

• Materials: Typically made of high-strength steel, aluminum alloys, or composite materials, with compressive strength, corrosion resistance, and low-temperature resistance.
• Safety: Equipped with pressure relief valves, temperature monitoring, and leak detection systems to ensure safe operation.
• Insulation Design (LNG tanks): Double-walled structure with insulation material in between to reduce heat transfer.
• Standard Compliance: Must comply with international standards such as ASME, API, or ISO to ensure safety and reliability.

Uses

• Energy Supply: Provides a stable supply of natural gas to industries, power plants, or homes.
• Transportation: Used for natural gas transportation, such as LNG carriers or CNG vehicle fuel tanks.
• Strategic Reserves: Stores natural gas in case of energy shortages or emergencies.
• Peak Shaving: Balances natural gas supply and demand, especially during peak winter periods.

Advantages

• Efficient Storage: After compression or liquefaction, natural gas occupies less space, making it easier to store and transport.
• Environmental Protection: As a clean energy source, natural gas storage tanks support its widespread use and reduce carbon emissions.
• Flexibility: Suitable for small vehicle fuel tanks to large industrial storage facilities.
