FUGITIVE EMISSIONS - eng.utoledo.edu

In case of leaks from pipes, flanges, valves etc. emission factors are used to determine the releases. CALCULATION OF FUGITIVE EMISSIONS. Several methods have been developed to estimate the fugitive emissions. Widely used methods are given below: use of "Average" SOCMI Emission Factors;

IGES List of Grid Emission Factors | IGES Publication Database

A "grid emission factor" refers to a CO2 emission factor (tCO2/MWh) which will be associated with each unit of electricity provided by an electricity system. It is a parameter to determine the baseline emissions for CDM projects in the renewable energy sector (hydro, wind, solar PV, and geothermal power, etc.) and waste heat/gas recovery sector.

CO2 Emission Factors for Fossil Fuels - Umweltbundesamt

importance for emission factors, the German inventory uses country -specific emission factors rather than international, average factors. To determine such factors, one requires a detailed knowledge of the fuel compositions involved, especially with regard to carbon content and net calorific values.


However, it is preferred if you have data from a site-specific stack test to develop an emission factor for the source. HAPs: Usually you will have either SDS information or an AP-42 emission factor available to determine the HAP emissions. Sometimes only trade associations have emissions data and make it available only to members.


Emissions Factors for Equipment Leak Fugitive Components Addendum to RG-360A January 2008 5 SOCMI Factors Use the SOCMI factors to determine equipment leak emissions from chemical plants or chemical processes within refineries. SOCMI factors are divided into three categories: SOCMI average factors, "SOCMI with

Emission intensity - Wikipedia

In general, the use of country-specific emission factors would provide more accurate estimates of emissions than the use of the default emission factors. According to the IPCC, if an activity is a major source of emissions for a country ('key source'), it is 'good practice' to develop a country-specific emission factor for that activity.

• Some of the emission factors have been revised, and some new factors have also been included. The tables containing the emission factors indicate which factors are new, and which have been revised from the IPCC 1996 Guidelines and GPG2000. • The default oxidation factor is assumed to be 1, unless better information is available.
