    This fact sheet contains a worksheet that owners/operators of oil and gas facilities can use to calculate emissions from leaking components at their facility. It is designed for the equipment typically found at compressor stations but may be useful for other similar facilities. "Protocol for Equipment Leak Emission Estimates," Table   EPA, “Protocols for Generating Unit-Specific Emission Estimates for Equipment Leaks of VOC and VHAP,” (EPA, October ) also new version from Ref. unit specific emission.

    A volatile organic compound (VOC) emissions source is any process or production unit that uses materials that contain VOCs or creates emissions of VOCs. These include paints, inks, lacquers, adhesives, other coatings or cleanup and other solvents. This fact sheet focuses on VOC emissions sources within painting and coating operations. Emission estimates can be calculated from various methodologies described in the EPA publication Protocols for Generating Unit-Specific Emission Estimates for Equipment Leaks of VOC and VHAP.8 These methodologies differ in level of complexity; the more complex, the more accurate the emissions estimate.

    3) Equipment type, number, and usage estimates are used as given in the PEA, with the exceptions noted above in the general assumptions. Onroad Equipment Emission Calculations Assumptions 1) Emission factors are the latest available from the SCAQMD website, where the vehicles have been assigned three classes, passenger (i.e. employee vehicles. Emissions can be estimated with calculation methods presented in EPA (d) publications, such as Protocols for Generating Unit-Specific Emission Estimates for Equipment Leaks of VOC and VHAP (used for fugitive emissions).

Protocols for generating unit-specific emission estimates for equipment leaks of VOC and VHAP Download PDF EPUB FB2

The EPA’s protocol for estimating equipment leak emissions is the result of detailed information gathering and data analysis. The protocol was written to provide a thorough understanding of acceptable approaches to generating process unit-specific emission estimates.

In preparing this document. The steps involved in generating aunit-specific emissions estimate using correlations developed specifically forthat unit are: 1. Gathering of mass emission data and calculation of mass emission rate (leak rate); 2.

Development of leak rate/screening value correlations; 3. EPA has developed a Protocol for Generating Unit-Specific Emission Estimates for Equipment Leaks of VOC and VHAP.

The protocol provides several methods for estimating emissions from equipment leaks. These methods range from the application of average emission factors for the equipment component inventory to the use of bagging data for generating unit-specific leak rate.

According to this protocol, different approaches can be used to estimate. Because material in equipment within a process unit is often a mixture of several chemicals, equipment leak emission estimates for specific volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and/or pollutants under Section (r) of the Clean Air Act, as amended can be obtained by multiplying the TOC emissions from a particular equipment times the ratio of the concentration of the.
