“…Different theoretical models and investigations are developed by Eslamian et al [28,49,54,55] and Abbasi et al [56][57][58] to study the Soret effect. One of the main factors in estimating the thermodiffusion coefficient for associating and non-associating fluid mixtures is evaluation of the activation energy in Eyring's viscosity theory [59].…”

Thermodiffusion or Soret effect is a heat and mass transfer phenomenon in a non-isothermal liquid and gas mixtures. This phenomenon is more pronounced in oil fields, usually due to the porous environment. A precise and better understanding of the thermodiffusion phenomena in multi-component mixtures results in a more accurate modeling of oil reservoirs. Accordingly, the main objective of this study is to investigate the thermodiffusion phenomenon in the multicomponent mixtures. In order to achieve this objective, two series of thermodiffusion experiments conducted on board the International Space Station (ISS) using the SODI (Selectable Optical Diagnostics Instrument) facility were analyzed. The first series of experiments aimed to study the effects of the forced vibration on the Soret phenomena. The experimental mixture was water and isopropanol with different compositions subjected to various temperature gradients normal to the vibrations. Results revealed maximum separation for the case with the minimum vibration and the lower temperature gradient; however, a linear relationship between Gershuni number and maximum separation was not found. On the other hand, the second series of experiment was aimed to the measurement of the diffusion coefficients of selected ternary mixtures. Mixtures of tetrahydronaphthalene-isobutylbenzene-dodecane at five different compositions were hosted in the DSC (Diffusion and Soret Coefficient) cell array. Thus, the Soret diffusion coefficients and the molecular diffusion coefficients of the mentioned hydrocarbon mixture at five different compositions have been reported. To process the results of these experiments an advance image processing technique was developed and implemented in an application with GUI (Graphical User Interface) for the Mach-Zehnder interferometer (MZI). Then, the application of the windowed Fourier transformation (WFT) to analyze the heat and mass transfer problem using the MZI setup is proposed. Results show that the WFT noticeably improves the measurement of concentration. This improvement is more evident for the ternary. It was shown that about 10% underestimation of the Soret coefficient would be resulted; if an accurate determination of the thermal time for the MZI is not used. The reliability and the repeatability of the MZI apparatus on board ISS to study thermodiffusion for binary and ternary mixtures were shown.

“…[4] Previous studies of hydrocarbon compositional gradients have examined the influence of thermal, pressure, and molecular diffusion that leads to compositional variation due to fixed, but independent, thermal gradients in the horizontal and vertical directions [Riley and Firoozabadi, 1998;Ghorayeb and Firoozabadi, 2000b;Ghorayeb et al, 2003;Nasrabadi et al, 2007;Abbasi et al, 2011]. Here we allow the temperature to evolve dynamically due to advection of heat.…”

[1] We examine bulk fluid motion and diffusion of multicomponent hydrocarbon species in porous media in the context of nonequilibrium thermodynamics, with particular focus on the phenomenology induced by horizontal thermal gradients at the upper and lower horizontal boundaries. The problem is formulated with respect to the barycentric (mass-averaged) frame of reference. Thermally induced convection, with fully time-dependent temperature distributions, can lead to nearly constant hydrocarbon composition, with minor unmixing due to thermal gradients near the horizontal boundaries. Alternately, the composition can be vertically segregated due to gravitational effects. Independent and essentially steady solutions have been found to depend on how the compositions are initialized in space and may have implications for reservoir history. We also examine injection (to represent filling) and extraction (to represent leakage) of hydrocarbons at independent points and find a large distortion of the gas-oil contact for low permeability.

“…arbon dioxide capture helps with low carbon emission during fossil fuel utilization, which is very useful to achieve the carbon neutral goal. [1][2][3] For industry application, chemical absorption provides a great opportunity to capture CO 2 in a large scale. In chemical absorption, the solvents like amine solutions react with CO 2 to form the stable carbamate salts with high enthalpy of formation.…”

Carbon dioxide (CO 2 ) capture is an essential method for emission control. In CO 2 capture, although with the promising advantage of industrial application, chemical absorption meets the challenge of substantial energy consumption. Thus, an advanced solvent with liquid metal GaInSn/PANI/TEMPO has been first developed to reduce the energy consumption. The intensified thermoelectric effect between GaInSn/PANI/TEMPO has the potential to enhance the CO 2 desorption. Density functional theory (DFT) model and spherical mass transfer and energy transfer model in the nanoscale are developed to study the mass and energy transfer in CO 2 and GaInSn/PANI/TEMPO. The CO 2 fraction, electron density, and velocity in the nanodomain are studied. The symmetrical electron density zone is identified for the thermoelectric effect. The mass transfer coefficient is increased by twofolds. The thermoelectric conversion amount reaches 32.6-44.8% and the energy consumption is reduced to 1.07 GJ t −1 . The CO 2 desorption is finally proven to occur at temperature below 339 K.
