Evaporative Loss from Floating-roof Tanks, Fourth Edition
Handbook / Manual / Guide by American Petroleum Institute, 08/01/2020

Category:

Description

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).

Evaporative Loss from Floating Roof Tanks, Third Edition

Description

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, rim-seal systems, and deck fittings, as well as for various liquid stocks, stock vapor pressures, tank sizes, and wind speeds (EFRTs).

The equations were developed for:
a)stocks with a true vapor pressure greater than approximately 0.1 psia,
b)average wind speeds ranging from 0 miles per hour (mph) to 15 mph (EFRTs), and
c)tank diameters greater than 20 ft.

The estimation techniques become more approximate when these conditions are not met.

When this standard is used to estimate losses from non-freely vented (closed vent) internal or domed external floating-roof tanks (tanks vented only through a pressure-vacuum relief vent, blanketed with an inert gas, vented to a vapor processing unit, or otherwise restricted from being freely vented), refer to the methodology in API TR 2569.

The equations are not intended to be used in the following applications.
a)To estimate losses from unstable or boiling stocks (i.e. stocks with a true vapor pressure greater than the atmospheric pressure at the tank location) or from petroleum liquids or petrochemicals for which the vapor pressure is not known or cannot readily be predicted.
b)To estimate losses from tanks in which the materials used in the rim seal, deck fittings, or deck seams have either deteriorated or been significantly permeated by the stored stock.
c)To estimate losses from storage tanks which do not have a floating roof.
d)To estimate losses from landing floating roofs (API TR 2567 addresses this).
e)To estimate losses from cleaning storage tanks (API TR 2568 addresses this).

Evaporative Loss Measurement: Documentation File for API Manual of Petroleum Measurement Standards Chapter 19.2 – Evaporative Loss from Floating Roof Tanks
Handbook / Manual / Guide by American Petroleum Institute, 04/01/1997

Category:

Description

Describes improved methods for estimating total evaporative losses or equivalent atmospheric hydrocarbon emissions from external, internal, and covered floating-roof tanks containing multicomponent hydrocarbon mixtures or single-component stocks. Chapter 19.2 consolidates previous API publications 2517 and 2519. This standard includes the following new information:roof/deck fitting factors for internal and external floating roof tanks for wind speeds up to 15 mph, rim seal loss estimating equation, wind speed correction factor for external floating roof fittings, and a method for estimating emissions from domed floating roofs.
