Research paper thumbnail of Comparison of the SRK and CPA equations of state for physical properties of water and methanol

Fluid Phase Equilibria

Accurate modelling of reservoir fluids containing hydrocarbons, water, and a hydrate inhibitor is... more Accurate modelling of reservoir fluids containing hydrocarbons, water, and a hydrate inhibitor is an important area for the petroleum industry. Often cubic Equations of State as for example the SRK equation are used. It is ...

Research paper thumbnail of Thermodynamic modeling of hydrate dissociation conditions for refrigerants R-134a, R-141b and R-152a

International Journal of Refrigeration, 2012

ABSTRACT In this communication, a general model is presented for estimating hydrate dissociation ... more ABSTRACT In this communication, a general model is presented for estimating hydrate dissociation conditions for refrigerants R-134a, R-141b and R-152a which employs the cubic plus association equation of state (CPA EoS) for modeling the fluid phases and van der Waals –Platteeuw statistical model for the hydrate phase. The Kihara potential parameters for the latter refrigerants are estimated by employing an implicit optimization scheme using minimization of the chemical potential difference of water in the hydrate and in the liquid phase. The minimization was performed by applying genetic algorithm. Using this model, the agreement between the experimental data and the model results is found acceptable.
