Hydrate Enthalpy and Hydration Number from Phase Equilibrium

6 Hydrate Enthalpy and Hydration Number from Phase Equilibrium 

The enthalpy of hydrate formation of simple natural gas hydrate formers (from gas and water or ice) is given in Table 4.7 taken from the dissertation of Kamath (1984). Note that each component has two temperature regions, above and below the ice point, with a A77 difference related by the heat of fusion at the ice point.

The intention of this section is to relate these enthalpies both to the phase equilibrium values and to show how these values relate to microscopic structure and to hydration numbers at the ice point.
