Název v původním jazyce

Model for gas hydrates applied to CCS systems part I. Parameter study of the van der Waals and Platteeuw model

Popis výsledku v původním jazyce

In this study, divided in a series of three articles, the model for pure CO2 hydrate by Jäger et al. (2013) has been improved and extended to other gases relevant in Carbon Capture and Storage (CCS) applications. The new model based on the van der Waals and Platteeuw (vdWP) approach is combined with highly accurate equations of state (EoS). Part I describes a critical analysis of the main parameters of the vdWP-based hydrate model. The influences of the specific hydrate volume, of the Langmuir constant, and of the EoSs used for other phases than hydrate on the predicted hydrate composition and on phase equilibria with hydrates were investigated. A new correlation for the pressure dependency of the volume of gas hydrates forming structures sI and sII has been developed. A strong influence of the Langmuir constant on the hydrate composition was observed. Additionally, the influence of EoSs used for other phases than hydrate on the accuracy of quadruple point predictions is discussed.
