API PUBL 4678

Annotation of standard text API PUBL 4678 :

This publication is volume two 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 describes theoretical concepts and equations that may be used in a model (APIDRAIN) to estimate speciated VOC emissions. The model can provide insight on how to change process drain variables (flow rate, temperature, etc.) to reduce emissions. See also Publs 4639, 4677, and 4681. See more
