Abstract

The gas hydrate-liquid water-vapor (H-LW-V) equilibrium conditions of multicomponent gases i.e. Synthetic Natural Gas A (SNG-A) and Synthetic Natural Gas B (SNG-B) in which both have high concentration of carbon dioxide, CO2 i.e. approximately 69% are measured. In addition, the hydrate-phase equilibrium in the presence of thermodynamic inhibitor of ethylene glycol at 10 wt. % and 20 wt. % is also investigated at 30 to 60 bar range of pressure. Experimental results showed that the gas hydrate equilibrium conditions were shifted to the inhibition region in accordance with the increased ethylene glycol concentration. Comparison of experimental temperature suppression caused by the addition of ethylene glycol with the results predicted by commercially used gas hydrate software, CSMGem showed slight deviation. Further study on the modeling calculations of gas hydrate equilibrium conditions is recommended to get better predictions of gas hydrate equilibrium conditions.
