The formation of gas hydrates is considered as a potential for oil and natural gas pipelines blockage and operational problems. It is also argued that gas hydrates can be considered as an alternative method to separate gases and many positive applications. The presence of additives in an aqueous solution can play an important role in determining gas hydrate formation conditions. In this work, hydrate dissociation conditions for the N 2 + ethanol + water system, the N 2 + 1-propanol + water system, and the CO 2 + tetra-butyl-ammonium fluoride (TBAF) + water system have been measured and are reported. The mass fractions of alcohols were 0.05, 0.10, 0.20, and 0.30. The mass fractions of TBAF were 0.05 and 0.10. The experimental measurements were performed using an isochoric pressure search method (synthetic nonvisual method) in the 262.87−294.52 K temperature range and 0.79−33.06 MPa pressure range. The viability of the method used was verified by the experimental determination and comparison with previously published data in the literature of hydrate dissociation conditions for the N 2 + H 2 O system, the CO 2 + C 2 H 6 O + H 2 O system, and the CO 2 + N 2 + TBAB + H 2 O system. Finally, the thermodynamic inhibition and promotion effects of ethanol, 1-propanol, and TBAF in aqueous solutions are discussed in terms of hydrate dissociation pressures and temperatures
