(27e) Fuel Based Approach for CO2 Emission Factor Estimation

Global warming is an issue facing the world nowadays and CO₂ emissions are contributing directly to this issue. There are many ways to quantify and predict CO₂ emissions from different sources. Combustion process is considered to be the major source of CO₂ emissions. There are many published CO₂ emission factors in order to find the released emissions. In this study, CO₂ emission factors from fuel specifications for oil and petrochemical industry is used and compared with the published data. It was found that CO₂ emissions vary with quality of fuel and operating condition. For example, the average CO₂ emission factor for gas turbine was calculated as 114 lb/MMbtu. This emission factor has a good match with published emission factor of EPA and CAPP data.
