In
this work, the formation kinetics of cyclopentane (CP) + methane
hydrate is studied. CP is used as a promoter to accelerate the hydrate
formation. The total methane consumption, the induction time, and
the formation rate were investigated under different hydrate formation
conditions in NaCl solution. The results indicated that the pressure
driving force could increase the gas consumption and shorten the induction
time. Meanwhile, the induction time could be greatly influenced by
the pressure driving force at a lower temperature. Especially, it
could be shortened to a minimum value of 110 s with the increase of
the pressure driving force at a fixed operating condition (CP concentration,
7.45%; NaCl solution concentration, 3.50%; and temperature, 298.15
K). Moreover, the hydrate formation rate would be accelerated with
the increase of the stirring rate by its promotion in the dissolution
and dispersion of methane. Finally, a higher CP concentration was
favorable for the rapid hydrate formation of CP + CH4 binary
hydrates. The amount of CP used could determine the amount of methane
incorporated into the hydrate phase.
