A bstract : A new thermodynamic model for calculating the hydrate formation temperature of different hydrate formers in aqueous solutions of both electrolytes and alcohols is described. This method uses a generalization of the Aasberg‐Petersen model for water activity. To calculate the activity of water in the presence of electrolytes, the effect of alcohols was taken into account without using any new fitting parameters. The results are in good agreement with published experimental data. Calculated values of the hydrate forming temperature in the presence of alcohols and electrolytes are compared with values calculated by using other models.
