In this study, the distribution of odorant in a natural gas pipeline network is investigated using Computational Fluid Dynamics (CFD) techniques. The focus is on an injection-type odorizer, with the odorant distribution analyzed using finite element methods up to a distance of 1 kilometer from the injection point. Key parameters influencing the performance of the injection pump, such as injection time, injection volume, and the number of pulses, are examined. Moreover, the modeling results indicate that the odorant concentration stabilizes at approximately 200 meters from the pipeline›s origin. Additionally, when the CGS gas station operates at a capacity of 7000 m³/hr, the odorant consumption exceeds the required amount. Even with a reduction in injection volume from 200 mm³ to 100 mm³, the output concentration remains within standard limits. Under lower loading conditions, the final odorant concentration reaches about 85 mg/m³, which is nearly four times than the standard level, resulting in a pronounced odor in the area. Ultimately, for the specified CGS gas station, optimal values for the pump›s performance parameters during both day and night hours are identified. Also, the optimal injection rate of odorant is 16 pulses per minute during the day and 8 pulses per minute at night.
