What is a tank battery and what components does it typically include?

• A. A tank battery is a simple storage tank with no processing.
• B. Tank battery combines separators, heaters, storage tanks, and measuring equipment to process and store crude before pipeline transport.
• C. A tank battery is a chemical reactor for upgrading crude.
• D. A tank battery is a flare stack used for gas disposal.

Answer: (B)

A tank battery is a field facility that prepares crude oil for pipeline transport by conditioning and storing the fluids. The key idea is that it does real processing, not just storage, so the oil is separated, heated as needed, and measured before it moves on.

The typical components are separators to separate oil, water, and gas; heaters to raise temperature for easier flow and more effective separation; storage tanks to hold the crude; and measuring equipment to monitor volume, quality, and flow. This combination handles both conditioning and containment, which is why it’s described this way.

Other descriptions that imply only a simple storage tank, or that refer to a chemical reactor or a flare stack, don’t capture the processing and measurement functions that define a tank battery.
