چکیده    One of the important, practical and simple methods for hydrate formation condition is empirical equations, and so far many empirical equations have been presented to predict the temperature and pressure of hydrate formation.in this study, the methods and empirical correlations have been reviewed and their predictive capabilitieshave been evaluated with the use of more than 2000 experimental data collected from literature. these data have been separated in three groups: (1) simple natural gas components included methane, ethane, propane,isobutane, carbon dioxide, nitrogen, and hydrogen sulfide (2) binary gas mixtures and (3) gas mixture similar to natural gas.in this paper, after expressing the restrictions of some empirical correlationshave been proposed by scientists before and proposed empirical correlation in the present study, the results of evaluating have been presented in several tables and curves.the proposed empirical correlation in the present studyhas shown reliable performance for both simple natural gas components and mixtures. despite the existence three adjustable parameters, the accuracy of this equation shows the ranking 1 to 3 compare to the rest of the equations.
