Experimental Study and Modelling of Cyclopentane Hydrates in the presence of NaCl, KCl and a mixture of NaCl -KCl

Sessions : Gas Hydrate FundamentalsInternational audienceResults from an experimental study of cyclopentane hydrate in the presence of NaCl (0 –23% t), KCl (0 -20% wt) and an equi-massmixture of NaCl-KCl (0 -22% wt) following a quick and a slow dissociation procedures are reported. The results show that the equilibrium temperatures of cyclopentane hydrate dropped significantly with an increase in salt concentration . A temperature shift between the equilibrium temperatures following the quick and the slow procedure was also observed.Two thermodynamic approaches are then presented to predict the equilibrium temperatures. The predicted-equilibrium temperatures are in good agreement with the experimental ones
