摘要
To prevent the plug of hydrate it is important to study the relationship between temperature and pressure at which hydrate form and dissociate. An empirical correlation was developed to predict the equilibrium condition to form the gas hydrate with and without presence of inhibitors. Overall 600 data points of equilibrium, to form gas hydrate have used to obtain the empirical correlation. The overall average absolute deviations are found to have good agreement with the experimental data. The present study may be helpful for further understanding the correlation of gas hydrate formation equilibrium condition.
