Hydrate Model for CCS Relevant Gases Compatible with Highly Accurate Equations of State- II. Results and Implementation in TREND 2.0

Popis výsledku v původním jazyce

The fitted hydrate models presented in detail in part I of this contribution are in good agreement with the available experimental three phase equilibrium data, two phase data, and hydrate composition data. The model results for enthalpies of formation for the gas hydrates are in good agreement with experimental literature data. The developed hydrate models have been implemented in a software for the calculation of thermophysical properties TREND. The most accurate equations of state available for fluid phases of pure substances and mixtures have been implemented in TREND 2.0. Furthermore, equations for pure solid phases and the proposed gas hydrate models have been implemented. The phase equilibrium algorithms for fluid phases have been extended to all solid phases considered in this work. Thus, up to three fluid and solid phases in equilibrium can be predicted at given temperature and pressure, pressure and enthalpy, or pressure and entropy.
