摘要In this work, the phase equilibrium data of methane hydrate in tetrahydrofuran (THF) and tetra-n-butylammonium chloride (TBAC) mixed aqueous solutions were investigated in the temperature range of (279.6 to 301.5) K and pressure range of (3.74 to 11.62) MPa. The measurements were carried out at mass fraction of 0.019 THF with the mass fraction of 0.020, 0.050, 0.101, 0.201, and 0.340 TBAC, and 0.058 THF with 0.102, 0.202, and 0.340 TBAC. The phase equilibrium data were obtained by the isochoric pressure-search method. The results showed that the addition of THF + TBAC could remarkably increase the phase equilibrium temperatures compared to the equilibrium temperature of pure CH4 hydrate. However, the addition of THF + TBAC mixtures did not push the CH4 hydrates equilibrium temperature to a higher degree compared to the addition of single THF. In stabilizing hydrate crystals, the TBAC played a positive role when the concentration of THF was low, but a negative role when the concentration of THF became high.
