Abstract: Evaporation is the natural process where a liquid converts to a vapor. All liquids have a certain vapor pressure which depends on the surface temperature of the liquid and its composition, both of which impact evaporation. There are many potential sources of evaporation loss in the crude oil industry. One major source, which is the focus of this paper, is from fixed and floating roof storage tanks. In the past, industrys main concern was minimizing evaporation losses to help maximize the bottom line of the company. However, with the growing concern of volatile organic compounds (VOCs) polluting the air and the United States Environmental Protection Agency (EPA) implementing stricter regulations, the need to improve and accurately estimate evaporation losses was inherent. The American Petroleum Institute Manual of Petroleum Measurement Standards (API MPMS) Chapter 19 details equations for estimating the average annual evaporation loss from storage tanks. These equations are based on test tank and field tank data and have been revised since initial publication for more accurate estimations.
