Abstract
The Super-saturation condition has to be provided to form gas hydrates. Consequently,
the prediction of the guest molecule fraction in the aqueous phase is crucial in the study of the gas
hydrate kinetics. In the present work, several experiments were carried out in a semi-batch reactor
in order to determine the mole fraction of methane and ethane during gas hydrates formation
(growth stage). The temperature ranged from 274.15 to 284.15 K. The experiment pressure ranges
were 3100 to 7765 kPa and 950 to 2635 kPa for methane and ethane, respectively. The mole fraction
is proportional to pressure while it is not affected by temperature to a great extent. Furthermore,
the amount of guest dissolved in the liquid water was observed in the aqueous phase which was
fairly constant during hydrates formation.
