Abstract

The new technique for estimation of equilibrium water content (nonclathrated water) in hydrate saturated porous media depending on temperature and hydrate-forming gas pressure is discussed. Thermodynamic calculations are based on experimentally determined of pore water potential and water activity by the device WP 4 of Decagon. Two types of pore media are used in experiments: Artificial model glass beads, simples without holes (Glass beads), with specify pore-capillary sizes (samples CPG) and multimineral natural clay. The nonclathrated water content in experiments is in a good correlation with structure of the pore space and the temperature shift of hydrate conditions. The calculated values of nonclathrated water are in a good agreement with experimental date that were determined by the contact method.
