Monitoring Greenhouse Gases and Their Pollutions in Sarakhs Region Influenced by the Sourest Natural Gas Resource in the Middle East

Shahid Hashemi-Nezhad Gas Processing Company (S.G.P.C.), located in Sarakhs region of Iran, processes wells that consist of the sourest gases in Middle East. The gas entering the company from gas wells includes 3.5 percent H2S and 6.5 percent CO2 that is quite rare among similar wells for sweetening such large quantities as it does. As a result, greenhouse gases and their possible harmful results are sometimes unavoidable in the area. In this study, greenhouse gases in Sarakhs region, the atmosphere of the company and also the output metering of S.G.P.C. were monitored and analyzed in a three-month period, considering elimination of preliminary contaminants in the sweetening process. Later, sources, fluctuations and deviations of greenhouse gases from global standards were observed and analyzed.
