Abstract: Devising methods to prevent hydrate formation is of the important issues in natural gas industry. Since a great deal of money is annually spent on using hydrate inhibitors, identification of new inhibitors with higher degrees of efficacy is economically justifiable. Bearing in mind the significant role of hydrate inhibitors in prevention of natural gas pipelines' getting blocked, the present study attempts to investigate two compounds of NaCl and Na 2 SO 4 as inhibitors of hydrate methane's formation so as to respond to "what is the inhibitive thermodynamic impact of electrolyte compounds of NaCl and Na 2 SO 4 on the formation of methane hydrate?" To do so, this study not only measures the equilibrium temperature and pressure of methane hydrate formation in the presence of electrolyte solutions of NaCl and Na 2 SO 4 and compares the results obtained with the state lacking such inhibitors, but it also assesses the regression and mathematical modeling are utilized within a basic virtual environment in order to propose a model for prediction of thermo-dynamic equilibrium temperature and pressure of methane hydrate formation.
