Emissions from refinery process drains are under increasing scrutiny, particularly with regard to volatile organic compounds (VOCs) and hazardous air pollutants (HAPs), because of the Clean Air Act Amendments of 1990. This publication is volume one of a three-part study initiated by the American Petroleum Institute (API) to update the AP-42 emission factor for refinery process drains, which may overestimate refinery process drain fugitive emissions. This volume contains simplified emission factors that can be used to quickly estimate total volatile organic compound (VOC) emissions from refinery process drains. See also Publs 4639, 4678, and 4681.
