In this article a thermodynamic model is presented that predicts the hydrate formation conditions for systems that contain free water, water vapor dissolved in gas, methanol, and mixed gases both hydrate and non-hydrate formers. The model is verified with experimental data. For three-phase equilibria, it has an AADP of 8.86%. The corresponding value for two-phase equilibria is 6.07% and for systems inhibited with methanol, the AADT is 1.04%. A case study is conducted to present its applicability. For this, the Yamal-Europe gas pipeline on Polish territory has been selected with real operating data. The critical location at which hydrates are predicted to become stable together with the optimal hydrate combating settings for different methods are computed.
