Model for gas hydrates applied to CCS systems part II. Fitting of parameters for models of hydrates of pure gases
Original language description
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 approach is combined with highly accurate equations of state. In this article (part II), the new hydrate model is described. A multi-property fitting algorithm is presented, which allows for simultaneous fitting of the model parameters to hydrate phase equilibrium data and to various types of hydrate composition data. Kihara potential parameters and reference parameters of the hydrate model were evaluated for eight selected hydrate formers. Experimental data used as an input to the fitting algorithm were weighted using uncertainty estimates. New ad-hoc approaches were developed in order to estimate the uncertainties of chemical potential along the three-phase coexistence lines and the uncertainties of composition data.
