This standard contains methodologies for estimating the total evaporative losses of hydrocarbons from external floating-roof tanks (EFRTs), freely vented internal floating-roof tanks (IFRTs), and domed external floating-roof tanks (domed EFRTs).
The methodologies provide loss estimates for general equipment types based on laboratory, test-tank, and field-tank data.
Types of floating roofs, rim-seal systems, and deck fittings are described for information only.
The equations estimate average annual losses from floating-roof tanks for various types of tank construction, floating-roof construction, rimseal systems, and deck fittings, as well as for various liquid stocks, stock vapor pressures, tank sizes, and wind speeds (EFRTs). See more
