Carbon capture and storage (CCS) has attracted renewed interest in the re-evaluation of equations state (EoS) for prediction thermodynamic properties. This study also evaluates EoS Peng–Robinson (PR) Soave–Redlich–Kwong (SRK) their capability to predict properties CO2-rich mixtures. The investigation was carried out using machine learning such as an artificial neural network (ANN) a classified ...

New isothermal vapor–liquid equilibrium (VLE) data for the carbon dioxide + 1,4-dioxane system are reported at four temperatures (323.15, 333.15, 343.15, and 353.15) K pressures up to 122.7 bar. The critical curve was also measured 158.8 bar 420.15 K. Phase behavior measurements were performed in a high-pressure windowed cell with variable volume, using static-analytical method phases sampling ...

Solubility prediction of high molecular weight molecules in high-pressure solvents is an interesting field of research. Sometimes the solubility data are not available for several components due to lacking of valid equipments. Therefore, an accurate prediction technique can help the researchers. According to the literature, the simple Equations of State (EoSs) such as Soave-Redlich-Kwong (SRK),...

Convective numerical fluxes across elements interfaces calcul...

Ventilation Air Methane (VAM) refers to the release of fugitive methane (CH4) emissions into atmosphere during underground coal mining operations. Growing concerns regarding greenhouse effects CH4 have led a worldwide effort in developing efficient and cost-effective methods capturing CH4. Among these, absorption-based processes, particularly those using Ionic Liquids (ILs) are appealing due th...

the present study investigates the performance and relative accuracy of four lattice-hole theory based equations of state in modeling and correlating the liquid density of pure refrigerants. following the gathering of a database of 5740 experimental liquid density datapoints of 36 pure refrigerants belonging to five different categories including cfcs, hcfcs, pfcs, hfcs and hfes, ranging from 6...

The total solubility of ethylene in LLDPE presence propane, isobutane and 1-butene is measured using a gravimetric technique at 70 °C pressures up to 5 bars. In order overcome the lack experimental partial data ternary systems, novel approach for estimation Sanchez-Lacombe interaction parameters proposed. measurements combined with independent estimate compressibility factor mixture gases Peng-...

Critical comments on the entropic lattice Boltzmann equation (ELBE), by Li-Shi Luo, Wei Liao, Xingwang Chen, Yan Peng, and Wei Zhang in Ref. , are based on simulations, which make use of a model that, despite being referred to as the ELBE by the authors, is in fact equivalent to the standard lattice Bhatnagar-Gross-Krook equation for low Mach number simulations. In this Comment, a concise revie...

In this paper, we introduce and consider the concept of the prox-regularity of a multifunction. We mainly study the metric subregularity of a generalized equation defined by a proximal closed multifunction between two Hilbert spaces. Using proximal analysis techniques, we provide sufficient and/or necessary conditions for such a generalized equation to have the metric subregularity in Hilbert s...
