Top 5 Types of Oil Tanks and Their Uses in Storage

Oil storage plays a crucial role in the global energy industry, and selecting the right type of tank for your storage needs is essential. The choice of oil tank impacts not only the safety and efficiency of storage but also compliance with industry regulations. With various types of oil tanks available, understanding the different options will ensure that you select the ideal storage solution for your business.

In this article, we’ll explore the top 5 types of oil tanks and their unique features. These tanks are used for different purposes, depending on the nature of the product being stored, environmental concerns, and space availability. By understanding each tank type, you can make an informed decision and optimize your oil storage requirements.

1. Fixed Roof Tanks

Fixed roof tanks are the most common type of oil storage tank and are widely used for storing large volumes of less volatile products, including crude oil, gasoline, diesel, and kerosene. They are characterized by a rigid roof that does not move with the liquid level.

Why Choose Fixed Roof Tanks?

• Large-Scale Storage: Fixed roof tanks are well-suited for storing large quantities of oil. They are perfect for bulk storage and long-term reserves. The design provides maximum storage capacity, making them ideal for larger-scale storage operations.

• Cost-Effective: These tanks are cost-effective both in terms of initial investment and ongoing maintenance. The fixed roof design requires minimal maintenance compared to other tank types, making them a budget-friendly option for oil companies.

• Suitable for Stable Products: Fixed roof tanks are perfect for storing non-volatile oils, such as crude oil or diesel, that don’t require measures to prevent vapor loss. The stable nature of these products ensures that they can be safely stored in these tanks without significant evaporation issues.

Advantages of Fixed Roof Tanks:

• Easy installation and simple maintenance requirements.

• Low operational costs due to minimal need for adjustments.

• Long service life with proper maintenance.

Considerations for Fixed Roof Tanks:

• They are not ideal for storing highly volatile or flammable liquids due to evaporation risks.

• Fixed roof tanks have a higher potential for emission losses compared to floating roof tanks.

2. Floating Roof Tanks

Floating roof tanks are designed to minimize evaporation by adjusting the roof level with the oil stored inside. This makes them the ideal choice for storing volatile liquids like crude oil, jet fuel, and refined petroleum products. These tanks are commonly used in refineries and large-scale fuel storage operations.

Benefits of Floating Roof Tanks:

• Reduced Evaporation: One of the main advantages of floating roof tanks is their ability to minimize evaporation losses. The floating roof moves with the level of the liquid, ensuring that the air space above the oil is kept to a minimum. This is especially important for volatile products like crude oil, where vapor loss can result in significant environmental and economic consequences.

• Environmental Impact: Floating roof tanks help mitigate the environmental impact of oil storage by reducing volatile organic compound (VOC) emissions. This makes them a more environmentally friendly option compared to fixed roof tanks, especially in regions with strict environmental regulations.

• Ideal for Volatile Products: Floating roof tanks are designed specifically for storing volatile liquids. This makes them the preferred option for products such as crude oil and refined petroleum, which are prone to evaporation.

Advantages of Floating Roof Tanks:

• Minimizes evaporation, reducing both product loss and emissions.

• Cost-effective in the long term due to lower emissions and operational efficiencies.

• Complies with environmental regulations concerning emissions.

Considerations for Floating Roof Tanks:

• Higher initial cost compared to fixed roof tanks.

• Maintenance of the roof system requires periodic inspections and potential repairs.

3. Spherical Tanks

Spherical tanks are designed for high-pressure storage and are commonly used for storing gases such as propane, butane, and liquefied natural gas (LNG). The spherical shape is ideal for withstanding the pressure exerted by these products, making them the safest and most reliable option for pressurized substances.

Advantages of Spherical Tanks:

• High-Pressure Resistance: The spherical design is inherently stronger than cylindrical designs, providing better resistance to internal pressure. This is essential for the safe storage of gases and liquids under high pressure, such as natural gas or LPG.

• Compact Size: Spherical tanks can store large volumes of pressurized products in relatively smaller spaces. Their design allows for maximum volume storage in minimal space, which is beneficial for locations with limited land availability.

• Superior Durability: The spherical shape distributes pressure evenly across the tank, making it more durable and long-lasting compared to other types of storage tanks. This design minimizes the risk of structural failure under pressure.

Benefits of Spherical Tanks:

• High strength and durability under extreme pressure.

• Compact and efficient use of space.

• Ideal for storing gases and high-pressure liquids.

Considerations for Spherical Tanks:

• Higher upfront costs due to the specialized design and manufacturing process.

• May not be suitable for storing non-pressurized oils or liquids.

4. Underground Storage Tanks (USTs)

Underground storage tanks (USTs) are tanks buried below ground level and are ideal for areas with limited above-ground space or where environmental protection is a concern. USTs are commonly used in urban settings or locations with stringent environmental regulations.

Why Choose Underground Storage Tanks?

• Space-Saving: USTs are perfect for locations where above-ground space is scarce. These tanks are often used in urban environments or areas where land costs are high. By burying the tank underground, companies can maximize the available above-ground space for other uses.

• Environmental Protection: Being buried underground provides an added layer of protection from environmental elements such as weather damage, sunlight, and temperature fluctuations. USTs are also less prone to vandalism or accidental damage compared to above-ground tanks.

• Enhanced Security: Underground storage provides enhanced security for the stored oil, as the tank is less visible and more difficult to tamper with. This makes USTs a good option for high-risk areas or locations with security concerns.

Advantages of Underground Storage Tanks:

• Ideal for locations with limited space above ground.

• Protection from environmental elements and external damage.

• Increased security due to the tank being buried underground.

Considerations for Underground Storage Tanks:

• Installation can be costly and complex due to excavation requirements.

• Periodic inspections and maintenance are crucial to prevent leaks or contamination.

5. Horizontal Storage Tanks

Horizontal storage tanks are low-profile tanks that are placed horizontally rather than vertically. They are commonly used for smaller-scale operations or where space is limited, making them suitable for both commercial and industrial use.

Advantages of Horizontal Storage Tanks:

• Space-Efficient: Horizontal tanks take up less vertical space, making them ideal for areas with height restrictions or smaller installations. Their compact design allows them to be placed in more confined spaces.

• Easy Installation: These tanks are easier to transport and install compared to larger, more complex storage tanks. This makes them a good choice for operations that require quick deployment or temporary storage.

• Portability: Horizontal tanks are also portable, which makes them an excellent choice for temporary storage needs or projects that require flexibility.

Benefits of Horizontal Storage Tanks:

• Ideal for limited space and temporary storage needs.

• Simple installation process with minimal disruption.

• Portable and adaptable to changing requirements.

Considerations for Horizontal Storage Tanks:

• May not be suitable for larger-scale or high-volume storage needs.

• Requires regular monitoring to ensure proper functioning and efficiency.
