Gas Hydrates Phase Equilibria and Formation from High Concentration NaCl Brines up to 200 MPa
Gas hydrate phase equilibrium and kinetics at high NaCl concentrations (near and at saturation in solution) and very high pressures (up to ��200 MPa) are investigated to study the interplay of hydrate formation and salt precipitation. Limited experimental data above 80 MPa exist for hydrate phase eq...
