Abstract: Hydrate phase equilibrium of the ternary guest mixtures containing carbon dioxide, hydrogen and propane at two different compositions were determined. Addition of mole composition of 2.5% propane to the fuel gas (CO2 (40%)/H2 (60%)) mixture reduces the hydrate formation conditions by 66% at the temperature of 278.4 K. A Clausius-Clapeyron plot for the experimental results was plotted and from the slope, the enthalpy of hydrate dissociation was calculated. The enthalpy of dissociation of the mixed hydrate formed from a ternary gas mixture containing mole composition 38.1% CO 2, 59.4% H2 and 2.5% C3H8 was found to be 110 kJ · mol-1 and hence it was concluded that the mixed hydrate formed structure II (sII) hydrates. Whereas for the ternary gas mixture containing mole composition 80.0% CO2, 18.8% H2, and 1.2% C3H8, the enthalpy of dissociation of the mixed hydrate was found to be 78 kJ · mol-1 and hence we believe the mixed hydrate formed structure I (sI) hydrate. © 2013 Published by Elsevier B.V.
