Title: Assessment of fugitive emissions of photochemically reactive organic compounds from petroleum refining operations

Principal Investigator / Author(s): Peoples, Scott H

Contractor: Radian Corporation

Contract Number: A4-153-32


Research Program Area: Emissions Monitoring & Control

Topic Areas: Stationary Sources


Abstract:

The primary objectives of this study were:

1. To evaluate fugitive emissions from various components (e.g., valves, flanges, pumps, etc.) at petroleum refineries, and
2. To evaluate factors which contribute to differences in these fugitive emissions between refineries and air pollution control districts.

The technical approach for this study included:

1. Collection of an extensive amount of data on the populations of these components by component type, process unit and refinery.
2. Collection of an extensive amount of hydrocarbon screening data that were obtained to comply with fugitive emission inspection / maintenance rules
3. Development of database structure and extrapolation procedures adn compilation of fugitive emissions data for all refineries in California.
4. A Detailed evaluation of the effect on fugitive emissions of various provisions of air pollution control rules, and
5. A Detailed evaluation of differences in fugitive emissions between refineries and air pollution control districts.

The major conclusions of the study were:

1. Significant uncertainty exists in estimating emissions from refinery fugitive emissions on the basis of hydrocarbon screening data obtained to comply with fugitive emission inspection / maintenance rules.
2. Significant differences exist in the fraction of leaking components between individual refineries.
3. For components that are subject to the rule (nonexempt), there has been a reduction in emissions of between 56 and 91 percent as a result of fugitive emission control rules, and
4. Between 44 and 78 percent of refinery fugitive emissions come from components which are exempt from the rules.
