“…Several investigations have been conducted on less time-consuming, but accurate, techniques for determination of the hydrate phase equilibria in the presence of salts [34][35][36]. The DSC method has recently been introduced as a reliable and less time-consuming technique for hydrate equilibrium measurements [22,25,37]. In the DSC method, the dissociation equilibrium temperature is generally determined from the onset temperature (T onset ), which is defined as the intersection of an extrapolated baseline with a line tangent to the inflection of the endothermic heat flow curve [26,38].…”

Phase equilibria, structure identification, and dissociation enthalpies of HFC-134a hydrates in the presence of NaCl are investigated for potential application in desalination. To verify the influence of NaCl on the thermodynamic hydrate stability of the HFC-134a hydrate, the three-phase (hydrate (H) -liquid water (L W ) -vapor (V)) equilibria of the HFC-134a+NaCl (0, 3.5, and 8.0 wt%)+water systems are measured by both a conventional isochoric (pVT) method and a stepwise differential scanning calorimeter (DSC) method. Both pVT and DSC methods demonstrate reliable and consistent hydrate phase equilibrium points of the HFC-134a hydrates in the presence of NaCl. The HFC134a hydrate is identified as sII via powder X-ray diffraction. The dissociation enthalpies (ΔH d ) of the HFC-134a hydrates in the presence of NaCl are also measured with a high pressure micro-differential scanning calorimeter. The salinity results in significant thermodynamic inhibition of the HFC-134a hydrates, whereas it has little effect on the dissociation enthalpy of the HFC-134a hydrates. The experimental results obtained in this study can be utilized as foundational data for the hydrate-based desalination process.

“…So the solid-liquid equilibriums are of interest for the development of theoretical models and in application of the chemical industry [1][2][3][4][5][6]. As long as eutectic behavior is observed and the data for the pure substances are known it is possible to use the data obtained in any solid-liquid equilibrium experiment to calculate the activity coefficient in the liquid phase.…”

“…Recently, methods of using output data of differential scanning calorimetry (DSC) are suggested. Of the methods of measuring SLE, it was shown that differential scanning calorimetry is a rapid and sensitive technique, broadly used for determining the phase boundaries through the measurement of the heat effect during the phase transformation process [8][9][10].…”
