| Due to high storage capacity, high dissociation enthalpy, and the appropriate melting point of gas hydrates, these compounds have a potential for many industrial applications. Tetra n-butylammonium halides are typical guest molecule involved in the formation of semiclathrate hydrates. In this manuscript, the dissociation enthalpy of methane/carbon dioxide/nitrogen + Tetra n-butylammonium Chloride semiclathrate hydrates is evaluated using the Clausius-Clapeyron equation. The equilibrium data are measured in a 460 cm3 stirred batch reactor using an isochoric pressure-search method. The dissociation enthalpy data were evaluated in the temperature range of (275.15 to 304.75) K and the pressure range of (0.36 to 10.57) MPa at (0 - 0.36) mass fraction of Tetra n-butylammonium Chloride. The results showed that the utilization of Tetra n-butylammonium Chloride increases the amount of dissociation enthalpy of semiclathrate hydrates per mole of the hydrated gas. By increasing the mass fraction of Tetra n-butylammonium Chloride, the amount of dissociation enthalpy per mole of hydrated gas increased. | ||
