Above-Ground Tank

Definition

An above-ground tank is a large vessel used for storing liquids, typically situated above the surface of the ground. These tanks are commonly used in industries such as petroleum, chemical, water treatment, and agriculture.

Purpose

Above-ground tanks serve the purpose of safely storing various types of liquids, including water, fuel, chemicals, and other industrial fluids. They are designed to facilitate easy access for maintenance, monitoring, and filling or emptying operations. The use of above-ground tanks is essential for managing large volumes of liquid in a controlled and safe environment, thereby preventing leaks and contamination.

Examples of Use

1. Petroleum Industry: Large above-ground tanks are used to store crude oil, gasoline, and other petroleum products at refineries and distribution terminals.
2. Water Treatment Plants: These tanks hold treated water ready for distribution to residential and commercial areas.
3. Agriculture: Farmers use above-ground tanks to store water for irrigation and liquid fertilizers for crop application.
4. Chemical Plants: Facilities use above-ground tanks to store various chemicals used in manufacturing processes, ensuring safe and efficient handling.
5. Fire Protection: Above-ground tanks store water for firefighting purposes, providing a readily available source in case of emergencies.

Related Terms

1. Underground Storage Tank (UST): Tanks located below the ground surface, used for storing liquids, often for environmental protection reasons.
2. Secondary Containment: Systems designed to contain spills or leaks from primary storage tanks, often a requirement for above-ground tanks to prevent environmental contamination.
3. Tank Farm: A group of storage tanks located in the same area, typically used in the petroleum and chemical industries to store large quantities of liquids.
4. API Standards: Guidelines set by the American Petroleum Institute for the construction, maintenance, and operation of above-ground storage tanks to ensure safety and efficiency.
5. Spill Prevention, Control, and Countermeasure (SPCC) Plan: A regulatory requirement aimed at preventing oil spills into navigable waters, which includes guidelines for the use of above-ground tanks.

Notes

1. Above-ground tanks must comply with various industry standards and regulations to ensure safety and environmental protection.
2. Regular inspection and maintenance of above-ground tanks are crucial to prevent leaks, corrosion, and other structural issues.
3. Proper siting of above-ground tanks is important to avoid environmental hazards and facilitate easy access for operations and emergency response.
4. Secondary containment measures, such as dikes or berms, are often required to contain spills from above-ground tanks and protect surrounding areas.
5. Technological advancements have led to the development of above-ground tanks with enhanced materials and monitoring systems for improved safety and efficiency.
