Abstract The Extended UNIQUAC model and the SRK EoS were successfully applied to the systems H2S, H2S-H2O, H2S-H2O-gas hydrates, and H2S-H2O-NH3. Extended UNIQUAC parameters for H2S and HS- were successfully estimated in the systems H2S, H2S-H2O, H2S-H2O-NH3. Langmuir constants in the gas hydrate model presented by Munck (1988) were estimated for H2S. The gas hydrate model, the Extended UNIQUAC model and the SRK EoS were applied and successfully correlate the experimental data points found in the literature for the system H2S-H2O where gas hydrates are present. A major review of the open literature for the systems H2S, H2S-H2O (with and without gas hydrates), H2S-H2O-NH3, and H2S-H2O-CO2 were carried out. The review includes collection of a large amount of experimental data and a presentation of the most important VLE models. A presentation of the differences between the gas hydrate model presented by Munck (1988) and other authors in the open literature are presented.
