Abstract
Background and Objectives: Industrial processes are the major sources of environmental pollutants. Oil & gas processing are one of the industries which emitting several air pollution matters in to the atmosphere. The obtained results of CO2 emission in one of the Gas Sweetening unit of Iranian south oil company based on the field and deskwork calculations is presented in this paper.
Materials and Methods: Fuel analysis method is the best method for CO2 estimation from combustion sources. In this paper, CO2 emission factor for gas sweetening plants is estimated based on this method.
Results: The obtained results showed that total CO2 emission in selected unit is about 922212/97 (kg/d) and CO2 emissions for the separate parts of this unit are 579661/75, 12921/93 and 329629/29 for acid gas flare, gas flare and boilers respectively.
Conclusion: comparison between the separated parts of the studied units showed that emission of acid gas flare is higher than other sources (i.e about 63% of total CO2 emission), and by using the EPA default CO2 emission factors the CO2 emitted 1/2 % lower than the actual emission in the mentioned unit.
