What is a common characteristic of atmospheric storage tanks?

Atmospheric storage tanks are indeed characterized by their versatility in design, including various roof configurations. This adaptability allows them to accommodate different types of materials, including liquids, which can range from fuels to chemicals. The common roof designs include floating roofs, fixed roofs, and in some cases, combinations that are tailored for specific storage requirements and environmental conditions.

The design of a roof can significantly influence the tank's effectiveness in preventing losses due to evaporation and in providing safety against possible spills or exposure. For instance, floating roofs are used to minimize vapor loss in volatile substances, while fixed roof tanks are simpler and used for less volatile liquids. This diversity in roof designs is a fundamental characteristic that distinguishes atmospheric storage tanks from other types, such as pressurized tanks, which have more rigid design requirements due to higher operating pressures.
