摘要：

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 degrees 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.
