Experimental measurements are carried out on semiclathrate hydrate of carbon dioxide (CO2) in Tetrahydrofuran (THF) concentrations of 5% mass fraction and sodium chloride (NaCl) concentrations of 5% and 10% mass fraction in an aqueous system. The phase equilibrium data are issued for system of CO2 + THF + H2O + NaCl and also CO2 + THF + H2O. The competing effect of THF and NaCl on phase behavior of semiclathrate hydrate equilibrium is studied. It is found that the inhibiting effect of the NaCl is suppressed by the promoting effect of semiclathrate hydrates of CO2 in THF as promoter. The study, in general, shows that the semiclathrate hydrates of CO2 are more stable than the hydrates of pure CO2 in the real environments containing salts. So, using hydrate method for safe carbon capture and sequestration (CCS) application is recommended.
