Abstract

In this paper new equilibrium data has been obtained for methane hydrate in the presence of three thermodynamic mixed inhibitors: NaCl + DEG, NaCl + TEG and MeOH + TEG as well as for carbon dioxide simple hydrate in the presence of two glycols inhibitors, i.e. monoethylene glycol (MEG) and diethylene glycol (DEG) for various concentrations using constant volume method. In this work, measured equilibrium data has been reported for conditions, for which there is limited reported data. Thermodynamic model and general correlation of Heriot-Watt University have been applied for estimating the measured equilibrium data and good agreements between measured and predicted data were observed.
