compressed air storage tank

Types of compressed air storage tanks

A compressed air storage tank provides a buffer between the air compressor and the system using compressed air. These tanks serve several purposes depending on their type, the main two being to store excess compressed air and to separate moisture from the compressed air system. Compressed air storage tanks come primarily in two designs: vertical and horizontal.

• Vertical compressed air storage tanks

  Vertical compressed storage tanks are cylindrical storage tanks that compress air in an upright position. Vertical storage tanks are usually made up of steel material and commonly get utilized for the storage of water, fuel, or other liquids. Vertical storage tanks can hold up to 896, 579 liters (240, 000 gallons) of water. Due to the tank holding such large volumes, it appears as if it is standing tall. The height of the tank is greater than the width.

• Horizontal compressed air storage tanks

  A horizontal tank is a storage tank that is positioned horizontally or in a laid-back position. A horizontal compressed air storage tank comprises steel plates that are welded together in such a way that no liquid or fluid passes externally. This welded combination creates a secured and leak-proof horizontal storage tank. Horizontal tanks are usually located at refineries, petrochemical plants, and industrial places. Like vertical tanks, horizontal storage tanks can also be made of fiberglass, aluminum, and carbon steel. Some types of horizontal storage tanks come equipped with internal bladders that allow for even more secure and efficient product storage.

Specification and Maintenance of Compressed Air Storage Tanks

Proper maintenance of air tanks for compressors is essential for ensuring longevity, optimal performance, and safety. Following the manufacturer's guidelines is imperative, but here are a few general maintenance tips for a compressor air tank.

• Routine Inspection: Regularly inspect the storage tank to check for any visible signs of damage, such as dents, corrosion, or leaks. Pay close attention to the pressure relief valve and inspect it closely for functionality and any signs of wear or leaks. If the valve is blocked, try removing any debris by scraping it, but if it is damaged, see a professional. The valve must be replaced before using the tank.
• Maintain Proper Pressure: Always maintain the recommended air compressor tank pressure. Over-pressurizing can lead to catastrophic failure, while under-pressurizing can result in moisture buildup from inadequate dehydration.
• Drain Condensate: If the storage has a drain valve, open it regularly or as recommended to remove the tank condensate. This can help prevent rusting.
• Protect from Elements: If the storage tank is not protected from the elements, it is more likely to become damaged. Store it in a dry, sheltered space to prevent any further damage from exposure.
• Maintain Proper Temperature: If any part of the tank needs to be heated to maintain air compression, use insulating material to prevent heat loss. However, avoid overheating, as this can damage the tank and the air it stores.
• Regular Maintenance: Schedule maintenance of the air compressor storage tank and air compressor system to undergo routine checks, repairs, and servicing to keep the setups working effectively and safely.
• Follow Manufacturer Guidelines: When maintaining the air tank, always follow the storage tank manufacturer's instructions. Failure to do so may void the warranty or endanger the tank user's safety.

Compressed Air Storage Tank Scenarios

The versatile applications of the compressed air storage tank demonstrate its significance in various industries. Some of its uses include providing a stable supply of compressed air for different processes and reducing the frequency with which air compressors run, thus minimizing wear and extending the maintenance intervals of air compression systems.

Air receivers allow for peak shaving, which means they enable companies to handle peak demand without having to run their air compressors continuously. Additionally, compressed air storage tanks serve as buffer systems to absorb pressure fluctuations and provide a consistent supply of compressed air to downstream equipment and tools. Furthermore, these tanks facilitate the efficient drying and filtering of compressed air by allowing moisture to separate and settle at the bottom of the tank.

Horizontal compressed air tanks can store energy in the form of compressed air, which can be used to power pneumatic tools, machinery, and equipment. This makes it a valuable asset in manufacturing and construction settings where compressed air is an essential source of energy for various applications. It is also useful for companies that use air compressors as their main energy source to streamline production processes and reduce downtime.

To ensure safety, compressed air storage tanks are equipped with pressure relief valves and other safety devices. These mechanisms are intended to protect against over-pressurization and potential hazards, thereby ensuring the safe storage of compressed air. This highlights the importance of compressed air storage tanks not only for air compression management but also for the safety of industrial facilities.

How to choose a Compressed Air Storage Tank

• Determine air demands

  Before buying an air receiver tank, it's important to assess the expected air demand for pressure and volume requirements. Consider current applications and potential future needs to avoid undersized or oversized tanks.

• Evaluate compressor integration

  Ensure the air receiver tank works with the existing air compressor in use or the one planned for purchase. Check compatibility in terms of size if horizontally placed or height to reach the stacking. Also, determine similar connections and fittings for a smooth integration process.

• Consider available space

  Take tank placement into account based on air receiver tank dimensions. Make sure there's enough physical space at the intended location for the receiver tank while also allowing room to maintain and service it as necessary over time.

• Assess structural support

  If the air receiver tank will be mounted or stacked, ensure the surface it's sitting on has adequate strength and support to sustain the weight of the tank when full of stored compressed air without risk of collapsing or instability.

• Identify the mounting configuration

  Choose an appropriate mounting style for the air receiver tank based on how and where it needs to be positioned. Decide whether the tank should have legs for floor standing, brackets for wall-mounting, or flanges for under-deck/mid-mount...

• Verify code compliance

  Check that the selected air receiver tank complies with relevant industry standards and safety regulations, including construction codes, pressure vessel guidelines, and any other applicable legal requirements, to ensure proper operation and avoid legal issues.

Compressed air storage tank FAQ

Q1: How long can compressed air be stored?

A1: Compressed air can be kept for a very long time. However, storing compressed air for a long time may waste possible uses of the air. It is usually better to use compressed air shortly after making it.

Q2: What are the safety considerations when using compressed air storage tanks?

A2: It is very important to observe the storage tank's pressure. Using it at a pressure higher than its limit can cause it to burst. Also, ensure that the tank is well-grounded and that there are no leaks. When disconnecting the air hose from the tank, do it slowly to avoid any sudden release of air that can pose danger to anyone's health.

Q3: Can someone customize the size of a compressed air storage tank to fit their needs?

A3: Yes. Manufacturers can customize the size of a compressed air storage tank to fit someone's needs. Just make sure to discuss your specifications with the manufacturer so they can make a tank that will be perfect for your exact requirements.

Q4: What is the maintenance requirement for a compressed air storage tank?

A4: Regular inspection and tank cleaning are maintenance requirements for a compressed air storage tank. Depending on the tank's usage and the compress air storage tank's type, it may also require regular pressure testing.
