A rate-based non-equilibrium model is developed for CO2 absorption with the mixture of piperazine and potassium carbonate solution. The based on mass heat transfer between liquid gas phases each packed column segment. thermodynamic equilibrium assumption (physical equilibrium) considered only at gas–liquid interface chemical assumed in phase bulk. calculated coefficient from available correlati...

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 ...

Phasepy is a scientifically defined open-source package in python for computational thermodynamics. indeed calculates the interfacial properties and fluid phases equilibrium using an equation of state. In addition, enables scientists to optimize relevant parameters multicomponent vapor-liquid, liquid-liquid, or vapor-liquid-liquid mixtures. The can model continuous approach (combining cubic sta...

We study the existence of standing waves, prescribed $L^2$-norm (the mass), for nonlinear Schr\"{o}dinger equation with mixed power nonlinearities $$ i \partial_t \phi + \Delta \mu |\phi|^{q-2} |\phi|^{2^* - 2} = 0, \quad (t, x) \in R \times R^N, where $N \geq 3$, $\phi: R^N \to C$, $\mu > 0$, $2 < q 2 4/N $ and $2^* 2N/(N-2)$ is critical Sobolev exponent. It was already proved that, small mass...
