The objective of this study is to investigated of hydrate formation of sour gas in the presence and absent thermodynamic inhibitor of mono ethylene glycol(۱۰%). For this purpose, to determine the hydrate equilibrium curve with concentrations of MEG was selected (۱۰wt%). The results showed that the natural gas hydrate equilibrium temperature decreased about ۲.۸ K in the presence of ۱۰% wt of MEG. also we found that to determine the dissociation point for real gases using step heating path provides more reliable equilibrium date based on appropriate size of temperature a long with sufficient time for each isothermal step.
