Abstract: This paper presents the results of an experimental study on the formation of natural gas hydrates in aqueous solutions of sodium bromide (NaBr), sodium fluoride (NaF), and sodium iodide (NaI).Segments corresponding to the gas hydrate formation process were identified in the recorded time-dependent profiles of system temperature and cell pressure. The experimental results indicate that the induction time for hydrate formation increases with the salt concentration of the solution, whereas the equilibrium hydrate formation temperature decreases. These findings suggest that aqueous solutions of sodium bromide, fluoride, and iodide can serve as hydrate formation inhibitors.The effect of halide salt solution concentration on the onset time of hydrate formation was investigated. It was demonstrated that increasing the salt concentration extends the induction time and lowers the temperature at which hydrate formation begins. The relationship between equilibrium temperature and cell pressure was determined, showing that the equilibrium hydrate formation temperature decreases as the salt solution concentration rises.These findings suggest that aqueous solutions of sodium bromide, fluoride, and iodide can serve as hydrate formation inhibitors.
