文摘

Thermodynamic model for hydrate formers relevant in CCS applications was developed. A multi-property fitting algorithm was used for correlating parameters of the hydrate model. Novel procedures for the evaluation of experimental data were developed in order to obtain dimensionless criteria. Uncertainty of the chemical potential of water was predicted using estimates for the work of formation of hydrates. A direct correlation of the Langmuir constant from hydrate composition data was introduced.
