Different Types of Storage Tanks and Their Key Uses

Storage tanks are essential in almost every industry, such as oil and gas, petrochemicals, transportation, etc. These tanks are purposely manufactured for the containment of liquids, vapours, or gases, and each type is developed for specific materials. Since its establishment in 1986, Ali Yaqoob Trading., which has established itself as a leading supplier and servicing company of liquid vapour and gas handling equipment, has addressed the specific storage requirements of customers around the globe.

With decades of experience, the company has built a good reputation for offering high-quality storage tanks and related products that meet the diverse needs of the customers around the world.

This article examines some of the more typical instances of tank design and their use across a number of sectors of industry.

1) Fixed Roof Tanks

Fixed-roof tanks are among the most widely used tanks across many industries. A fixed roof is permanently attached over the cylindrical body of the tank, usually in a dome or cone shape. Their simple design makes them an affordable and low-maintenance option for industries like oil refining, water treatment, and chemical storage, offering a reliable and cost-effective solution that meets safety and regulatory standards. They are particularly useful in containing non-volatile & low-vapor pressure liquids like chemicals, water, or fuel oil, as these do not produce high quantities of vapour. Such tanks are built as simply as possible, as their strength is necessary for containing stable liquids to avoid contamination from foreign substances such as dust, rain, or debris. Oil refining, water treatment, and chemical storage are some of the industries where fixed-roof tanks are common.

2) Floating Roof Tanks

Unlike fixed roof tanks, floating roof tanks are designed for volatile liquids.

Floating roof tanks make use of a floating type of roof that minimises the emission of hazardous vapours, making them safer and more environmentally friendly for storing volatile liquids. The floating roof is secured every time there is a rise and fall in the liquid levels of the tank, thus sealing the upper area of the tank. The confined area assists with the risk of fires and explosions. These tanks are good for crude oil, gasoline and other similar liquids having high volatility and these are generally found in the oil terminals and refineries, while minimising pressure buildup and the risk of leaks or ruptures. Since they control substantial evaporation losses, floating roof tanks are a safer and more effective alternative in industries dealing with great quantities of volatile substances.

3) Bullet Tanks

Bullet tanks are called so because of the bullet/circular shape, and they are used in the storage of liquefied gases in high pressure, such as propane and butane. These tanks are very common in industries that store gases as liquids under pressure. Bullet tanks are found in LPG plants, gas filling stations and other gas applications where they assist in the safe storage and transportation of the gases. 

The bullet shape of these tanks is specifically engineered to withstand high pressures and high temperatures and, therefore, can be used in areas where a lot of pressurised gases are contained. Bullet tanks are built to spread pressure evenly, making them safe and strong enough to withstand harsh conditions such as industrial conditions, extreme weather, seismic activity / earthquake, and accidental impacts.

4) Horizontal Cylindrical Tanks

Horizontal cylindrical tanks create endless options for above-ground storage. They consist of structural saddles/legs and can be used to store water, oil, and some other substances. Due to their versatility, they tend to be used in industries such as agriculture, chemical processing, and manufacturing, where large amounts of liquids need to be contained. Because horizontal cylindrical tanks are easier to move and install, they are ideal for use in many industrial and commercial applications.

5) Spherical Tanks

Spherical tanks storing gases are commonly referred to as "sphere tanks" and are the most sophisticated tanks for the storage of gases under pressure. Since pressure acts equally on the surface, these tanks are best for liquefied natural gas (LNG), propane, and butane, all of which require high pressure. Due to the fact that optimal gaseous storage is of the utmost importance, spherical tanks are predominantly found in the petrochemical, natural gas processing, and LPG production industries. The sphere design improves safety, energy efficiency, and overall space use, while providing better insulation and durability. With more safety features and control systems, they ensure reliable and safe storage of liquefied gases.

6) Underground Storage Tanks (USTs)

An underground storage tank is a great storage option with environmentally friendly characteristics. These tanks are ideally used for storing petroleum products and other hazardous materials and are usually stored below the ground. USTs are used in high-safety zones such as gas stations and chemical plants. They prevent spills and contamination by being buried, protecting materials from weather and damage. Another advantage of this tank is saving space, making them ideal for tight areas. Built with strong, safe materials and monitoring systems, these tanks ensure secure storage. 

7) Industrial Process Tanks

Industrial process tanks are industrial use tanks designated to specific manufacturing or processing facilities that require certain materials to be stored in them. The tanks are usually fitted to the requirements of the materials they contain.

For example, corrosive chemicals or high-temperature liquids. Thermal treatment can be found in chemical plants for heavy and industrial pipes, food factories, or any other industries necessary for the effective handling of the material. They are designed with special coatings and strong construction to withstand high heat, pressure, and corrosive substances. 

Conclusion

Whether it is a low-pressure or high-pressure storage tank, the kind of storage tank used is very important in order to achieve safety, cost-effectiveness and efficiency within the industry. It is known that storage tanks are used in gas and liquid management in all industries, such as oil and gas, transportation, and petrochemical industries. Ali Yaqoob Trading. offers storage tanks on demand to meet the different needs of its clientele in the chemical, petrochemical, oil and gas industries.
