Abstract

Based on our previous method of prediction of equilibrium conditions in the separate solutions of electrolytes and alcohol, a combining rule for calculating hydrate formation temperature in the presence of both electrolytes and alcohol has been developed. In this method, the hydrate temperature in the presence of pure water is calculated and then this temperature is corrected for the presence of both electrolytes and alcohol. The average of absolute deviation for prediction of incipient of CO₂ and a typical natural gas hydrate in the mixtures of both electrolytes and alcohol was 0.96 K. The ability of the proposed model is also compared with other available methods.
