| Summary: | Introduction: Iran is located in the seventh rank in terms of CO2 emissions resulting from the combustion of fuel in the world. Asmari gas compressor station due to the several sources of contaminants are causing the release of large amounts of CO2 and CH4, which will cause damage to the environment and a change in the weather conditions. This study was aimed to assess the extent of the greenhouse emissions (CO2 and CH4) in a selected Asmari gas compressor station at National Iranian South Oil Company.
Materials and methods: In this study, the emission factor method, provided by various organizations, was used for determining emissions of CO2 and CH4 from sources.
Results: According to the results, the total amount of CO2 emissions in selected units is equal to 1825.533 tons/day and the total emissions of CH4, is equal to 2.473 tons/day. Among the sources of pollutants in the fixed combustion sources, turbines have the highest amount of CO2 emissions, and among the exit gas source (repair and maintenance activities), the highest emissions of CH4 belongs to the compressors.
Conclusions: The amount of CO2 emissions from indirect sources (electrical equipment) from natural gas are more than fuel oils for burning, and CH4 gas from volatile sources in the gas compressors have the highest emissions compared to other sources.
