In this study, the ethane hydrate decomposition was modeled at temperatures ranging from 272.15 to 275.15 and
pressure between 0.58 to 3.42 bars by using chemical affinity. This model use a macroscopic driving force that only
need initial condition (temperature and pressure) and final condition (the equilibrium conditions). The model does not
have the limitations of microscopic models such as heat and mass transfer coefficient. The parameters of model Ar and
K t were obtained for each experiment and all of correlation coefficient (r 2 ) are higher than 0.99. The results show
that the parameter of
T
Ar has a constant value. Then parameters of model were used for predicting experimental data
and variation pressures with time were shown. The results show that this method can predict the constant volume
experimental decomposition data very well for crystals I hydrate former.
