At present, the desulfurization of low sulfur natural gas in Tarim oilfield adopts hydroxyl iron oxide desulfurizer.In this paper, the practicability of environmentally friendly triazine aqueous desulfurizer in Tarim oilfield was studiedand the aim of reducing desulfurization cost and environmental protection is achieved.According to operation cost analysis, triazine aqueous desulfurizer is economical in treating natural gas with H2S content less than 3000ppm,and natural gas treatment with higher H2S content is feasible under environmental protection requirement.The operating cost of triazine aqueous desulfurizer is 5.26% lower than that of the conventional hydroxyl iron oxide desulfurizer.Compared with NaHCO3solution,triazine aqueous desulfurizer has the advantages of simple operation, safety and environmental protection, and low treatment cost, and is suitable for desulphurization of natural gas in test wells containing sulfur and desulphurization of loose gas in airtight loading units.With the increase of sulfur test wells, environmentally friendly triazine aqueous desulfurizer has broad application prospect in Tarim oilfield.
