A Generalized Correlation for Predicting Methane Hydrate Equilibrium Data in Pure Water and Aqueous Solutions of Chloride Salts at pressure up to 500 MPa

Azeez G Aregbe

A generalized empirical correlation for predicting methane hydrate equilibrium data in pure water and aqueous solutions of single sodium chloride, potassium chloride, calcium chloride and magnesium chloride salts is developed in this work. Contrary to the general thermodynamic approach which involves rigorous and complex computations, an easy-to-use prediction method is developed by regressing several experimental data for methane hydrate formation in pure water and aqueous salt solutions. The predictions from the generalized correlation show satisfactory agreements with all the experimental data reported in the literature and are more accurate than the results from the common hydrate prediction programs.
