The CO2e Economic Analysis Tool (CEAT) is a spreadsheet-based application for comparing project alternatives that are sensitive to GHG emission rates, emission levies, or other financial parameters. The tool is applicable to hydrocarbon…
Reviews the accuracy of various test methods for measuring the emissions of volatile organic compounds from natural gas fueled reciprocating engines. This white paper points out some deficiencies inherent in some of the test methods.
This white paper demonstrates that AERMOD contains formulation errors and does not currently provide accurate NOx estimates for sources (e.g., natural gas compressor stations) with shorter stacks. The white paper also demonstrates that a new building…
Volatile organic compounds (VOCs) are defined as non-methane, non-ethane hydrocarbons and have negative environmental effects, especially in the formation of ozone that creates smog. The combination of a gas chromatograph and a flame ionization…
Previous project reports and a white paper provided background and analysis of pipeline blowdown data reported to under under Subpart W of the GHG Reporting Program. Pipeline blowdown data reported for the 2018 calendar year released by EPA in late…
The CO2e Economic Analysis Tool (CEAT) is a spreadsheet-based application for comparing project alternatives that are sensitive to GHG emission rates, emission levies or other financial parameters. The tool is applicable to hydrocarbon transportation…
The available database on NO emissions from large-bore, gas-fueled internal combustion engines were evaluated. Based on these data the expected performance of various NO control approaches amenable to retrofit on in-use engines was projected.
The overall objective of this project is to develop a standard method for validating methane emission quantification technologies. This validation process is intended to be used to assess any technology that claims to quantify methane emissions…
The NOx emissions versus engine operating parameter setting profile was established during performance/emissions mapping tests of a two-stroke turbocharged (Cooper-Bessemer GMVH-lOM) compressor station engine. Rased on this profile the operating…
