solubility of high molecular weight n-paraffins in supercritical carbon dioxide has been a matter of interest to many researchers. however, not sufficient solubility experimental data are available although the methods by which the experimental data are obtained have many varieties. utilizing cubic equations of state is an effective method for solubility prediction of n-paraffins in supercritic...

The objective of this contribution was to explore the effect of thermodynamic model selection on predicting the solubility of hydrogen in Pyrolysis Gasoline (PYGAS). In order to do this, different combinations of cubic equations of state (EOS), cohesion functions and mixing rules were compared, using both own algorithms and those implemented in the PRO/II 8.0 process simulation software. The mo...

Abstract: Reliable knowledge of the thermophysical properties of pure compounds and their mixtures in the whole composition and a wide temperature and pressure range is a vital prerequisite for computer-aided synthesis, design, and optimization of chemical processes. Knowledge of the various phase equilibria is most important for the development of thermal separation processes (but also for oth...

Hydrogen (H2) is a clean fuel and key enabler of energy transition into green renewable sources method achieving net-zero emissions by 2050. Underground H2 storage (UHS) prominent offering permanent solution for low-carbon economy to meet the global demand. However, UHS complex procedure where containment security, pore-scale scattering, large-scale capacity can be influenced contamination due ...

Abstract Positive displacement expanders are widely investigated and theirs models commonly use the REFPROP database to evaluate fluid properties. However, estimating procedures in CFD using result heavy of CPU time. Therefore, a study has been carried out determine if simpler methods for property estimation suitable. The ANSYS CFX solver used includes number cubic equations state, namely, Redl...
