The objective of this investigation was to obtain basic data which are necessary to develop a new hydrate process for desalination of sea water. Three new hydrating agents, R13 (CC1F3), R23 (CHF3) and R152a (C2H4F2), and propane were selected. The pressure-temperature phase diagrams of each agent for pure water and aqueous NaCl solution were determined in the temperature range from 260 to 295 K and pressures up to 4.4 MPa. Based on the pressure-temperature data obtained, the necessary thermodynamic data, such as hydrate decomposition conditions, invariant points, heat of formation, and hydrate composition were determined.
