Abstract In this work, the influence of NaCl on natural sweet and sour gas hydrate formation in the pressure of 115 bar and isothermal conditions (8 °C) have been compared. Salt concentration in the experiments was in the range of 1-7 wt% and the inhibitor was used at a constant concentration of 0.5 wt%. The results show that the presence of salt has been more effective on inhibition time, hydrate growth and also kinetic inhibitor performance in the sour gas system due to the role of ions in decreasing the solubility of acidic gases of sour gas (including H2S and CO2) in water.

含盐含硫天然气水合物形成条件对比

摘要 在这项工作中,比较了 NaCl 在 115 bar 压力和等温条件 (8 °C) 下对天然甜酸天然气水合物形成的影响。实验中的盐浓度在1-7wt%的范围内,抑制剂以0.5wt%的恒定浓度使用。结果表明,由于离子在降低酸性气体(包括 H2S 和 CO2)溶解度方面的作用,盐的存在对酸性气体系统中的抑制时间、水合物生长以及动力学抑制剂性能更有效在水里。
