Correlation of Phase Equilibrium Data of CO2 + Water Mixtures Containing Gas Hydrate using NLF-HB and MF NLF-HB EoS |
| 초록 |
The reliable phase equilibrium data and prediction of CO2 + Water mixture are required for the CO2 sequestration process. Some of experimental data are available for water rich phase containing gas hydrate, which alsoagree well with the correlation data using NLF-HB EoS(Hydrogen Bonding Non-random Lattice Fluid EoS). But for CO2 rich phase, experimental data are rare and also the correlation results with one binary energy parameter fitted from water rich phase data could not explain the experimental data. Two binary energy parameters based on multi-fluid approximation had been introduced in this study. The phase equilibrium data of LW-LCO2, LW-H-LCO2, LW-H-V, and LCO2-H were correlated with NLF-HB Eos and MF NLF-HB Eos. The correlation results of experimental data of CO2 rich phasewith two binary energy parameters were betterand water rich phase data were correlated well with both models. |
