Résumé :

En vue d'optimiser l'aération de substrats liquides à forte charge organique dissoute, un système d'aération fonctionnant selon te principe du "cheminement prolongé" a été conçu et construit à l'échelle pilote (3 000 L). Le principe mis à l'essai consiste à injecter de l'air à la base de longs tuyaux enroulés. La dynamique hydraulique du système à cheminement prolongé a été caractérisée. Un système d'aération plus conventionnel, soit un injecteur d'air de type poreux, a été utilisé comme base de comparaison. Les performances d'oxygénation des deux systèmes ont été mesurées dans l'eau, sous les mêmes conditions, puis comparées entre elles et aux valeurs rapportées dans la littérature pour d'autres systèmes. Les principaux résultats montrent que le coefficient de transfert d'oxygène (KL.a) est bon à l'intérieur des tuyaux de l'aérateur à cheminement prolongé (jusqu'à 230 h-1). Le nouveau prototype démontre également une forte capacité d'emprisonnement de l'air puisque le gonflement atteint 20 %. Finalement, de bonnes efficacités énergétiques ont été obtenues : des valeurs brute de 1.9 kg O2/kWh et nette de 9.2 kg O2/kWh ont été atteintes. Le prototype, tel que construit, a offert des performances. d'oxygénation globales similaires à cettes démontrées par l'injecteur d'air de type poreux, le volume interne des tuyaux, qui présente un intérêt particulier pour le transfert d'oxygène, ne représentant que 26 % du volume liquide total. L'optimisation de l'aérateur à cheminement prolongé passe donc par l'accroissement maximal du volume interne des tuyaux par rapport au volume liquide total. Cette mesure se traduirait par une augmentation de la capacité d'oxygénation totale et des efficacités physique et énergétique du transfert d'oxygène, ainsi que par une diminution des puissances spécifiques requises. Les performances du système à cheminement prolone dans un liquide chargé en substrat organique restent à étudier, mais les résultats préliminaires obtenus dans l'eau du robinet sont encourageants.

Résumé :

Des expérimentations menées sur des modèles-colonnes de milieu poreux, se localisant sur des études de lessivage du corps d'imprégnation formé par des mélanges d'hydrocarbures et sur des essais de propagation de leurs parties solubles, ont été réalisées au laboratoire. Il est montré que le comportement des hydrocarbures en solution pendant le lessivage est fonction de la nature de la source de pollution, et que le transport des traces solubles d'alcanes est fortement freiné par les effets de l'échange liquide-gaz masquant les propriétés adsorbantes de la matrice solide, ou pouvant entraîner une modification du processus de sorption des hydrocarbures par la phase solide. La solubilité n'est pas un critère suffisant pour expliquer la dissolution sélective et progressive des constituants d'un corps d'imprégnation formé par un mélange de plusieurs espèces d'hydrocarbures, et lors du transport des parties solubles d'une telle source de contamination, l'influence des paramètres solubilité, constante de Henry et coefficient de distribution doivent être pris en compte simultanément pour étudier leur rétention sélective.

Résumé :

Les transferts d'eau dans le sol sont généralement, pour des raisons de facilité, supposés se dérouler dans des conditions isothermes. Les modèles proposés couplant les transferts hydriques et thermiques se heurtent aux difficultés inhérentes à la détermination des coefficients de transfert. Disposant de l'évolution de la température, de la succion et de la teneur en eau dans les profils du sol de lysimètre, une comparaison portant sur l'importance des gradients hydriques et thermiques dans le transfert d'eau en phases liquide et vapeur a été menée. Il se dégage clairement, que dans le domaine de teneurs en eau qui intéressent l'agronome (teneur en eau supérieure à celle au point de flétrissement), l'essentiel des transferts se fait via la phase liquide. En effet, les flux dus aux gradients de teneur en eau dépassent d'au moins deux ordres de grandeur les flux induits par les gradients de température. Ce qui confirme bien la validité des équations de Darcy-Richards (DARCY, 1856; RICHARDS, 1931) où l'effet de température est négligé.

Résumé :

The transport of liquids driven by capillary suction-pressure and balanced by both viscous drag force and gravity acceleration is known as spontaneous imbibition. The prediction of spontaneous imbibition in porous media is of importance due to its relevance as a fundamental phenomenon in numerous industrial technologies as well as in nature. A vast majority of the experimental results and mathematical models concerning the imbibition process of single-phase liquids are considered and analyzed in the literature. The present research focuses on two-phase liquids transport in porous medium driven by capillary force. The penetrating liquids were surfactant-stabilized emulsions with the different dispersed phase concentrations. The discussed issues are the influence of porous bed composition and inner phase concentration on the height of an emulsion penetration, which allows to predict the velocity of imbibition process. From a practical point of view, the experimental results give the possibility to evaluate: productivity of granular sorbents applied to recover the environment, efficiency of building materials wetting with multiphase liquids, process of oil-derived pollutants migration in porous media, e.g. soil and other rock structures, etc.

Résumé :

The rate of transport of liquids in porous environment is crucial engineering problem. It has importance in many fields like chemical engineering, hydropedology, economic geology and also in building materials science. The intensity of a liquid transport in porous body can be analyzed be means of three concepts – sorptivity, permeability and diffusivity. The approaches applied in field of porous rocks are discussed. Water absorption coefficients of set of sedimentary rocks of wide porosity range were determined experimentally and the relationship between them and specific pore volume of rocks was found.

Résumé :

Proper characterization of contaminants in subsurface helps to clean up effectively the contaminated sites. In this study, different methods were used to quantify non-volatile light non-aqueous phase liquid (LNAPL) and water from sample columns subjected to different water to LNAPL ratios. The objective of the study was to evaluate methods for porous media water and LNAPL contents analysis. The liquids were sampled from the sample columns using activated carbon pellets (ACP). Sample columns water content was also measured using soil moisture sensors. Dielectric mixing model (DMM) was evaluated for the estimation of LNAPL content after water and LNAPL contents of the sample columns were determined through gravimetric analysis method. The result shows that it was possible to sample both water and LNAPL using ACP proportionally but with high standard deviations. It also shows that more liquid was sampled from sample columns subjected to only one liquid compared to sample columns subjected to two liquids. On the other hand, analysis of water and LNAPL using gravimetric analysis method gave the best result although the presence of LNAPL resulted in underestimation of water content at higher LNAPL contents. Meanwhile, the presence of LNAPL modified the bulk relative permittivity (ε<sub>a</sub>) of the sample columns and resulted in overestimation of water contents measured using soil moisture sensors at higher LNAPL content. The modification of ε<sub>a</sub> was used for the estimation of LNAPL using DMM. The evaluation of the model with known water and LNAPL contents and in estimating the LNAPL content of the other sample columns shows that the model could be used for the proper estimation of LNAPL in porous media.

Résumé :

1-alky-3-methylimidazolium hexfluorophosphate ([n-Cnmim][PF6]) and 1-alky-3- methylimidazolium thiocyanate ([n-Cnmim]SCN) (n=4,8,16) were firstly introducing into the casting solution (PSF/NMP), porous polysulfone (PSF) membranes were successfully prepared by the wet-phase-inversion. The scanning electron microscope was utilized to visualize the cross-sections of the membranes, in order to study the influence of ionic liquids with different alkyl chain on the porous structures. The results indicate that the PSF membranes have different structures and separation properties due to ionic liquids with different alky chain. For ionic liquids with the short alkyl chain, the prepared membranes have the porous structure on cross-sections, but no or weak separation properties. However, for ionic liquids with the long alkyl chain, the prepared membranes have both porous structure and good separation properties. According to the structure of a hydrophobic straight-long alkyl and a hydrophilic limidazolium ring, the ionic liquid with long alkyl chain is considered as a surfactant, it can change not only the interface properties between the casting solution and coagulation bath, but also induce the space structures of the polymer chains.

Rice, maize and potato starches were hydrolyzed by amylase to obtain porous starches as final product. The adsorptive capacity, desorbed rates, degree of crystallinity and retrogradation properties of native and porous starches were investigated. The results showed that porous starches had the stronger adsorptive capacity and slower desorbed rate compared with native starches. In the three starch materials, the adsorptive capacity of rice starch for liquids was the strongest; the adsorptive capacity of potato starch for liquids was the weakest. the more flavors adsorbed, the more flavors desorbed. X-ray diffraction showed that Enzyme hydrolysis did not result in any significant changes in the degree of crystallinity of starch. The porous starches exhibited lower tendency of retrogradation as assessed by differential scanning calorimetry (DSC).

Résumé :

Abstract During downward vertical flow of a viscous solution, the viscous fingering (VF) phenomenon affects miscible displacement of solutes through a soil profile. On the other hand, during horizontal flow, when the liquid residing in a horizontal bed of porous materials is displaced by another liquid of different density, the resulting hydrodynamic dispersion is modified by the formation of a tongue of denser liquid undershooting the less dense liquid, a phenomenon known as gravity segregation (GS). To explore VF and GS phenomena, the authors present laboratory experimental results on the vertical and horizontal transport of bulk solution and ions of different concentrations and/or densities through inert and reactive porous media. The study showed that, with miscible liquids, breakthrough starts later and ends earlier. The authors predicted the behavior of immiscible liquids by the nondimensional gravity segregation number β: that is, with increase in β, the segregation becomes extreme. The curve fitting technique CXTFIT 2.0 fitted the experimental breakthrough curves well, showing that the apparent coefficients of hydrodynamic dispersion vary much less with pore-water velocity in horizontal than in vertical flow, but retardation factors are not influenced by the orientation of flow. This work is relevant to the preferential flow of viscous liquids such as liquid fertilizers in agricultural fields, oil recovery processes, and the intrusion of saline water into the freshwater of coastal aquifers.

Résumé :

ABSTRACTThe non-equilibrium self-consistent generalized Langevin equation (NE-SCGLE) theory of irreversible processes in liquids has been proposed as a theoretical framework capable of predicting the age- and preparation-dependent properties of highly ubiquitous non-equilibrium amorphous solids, such as like glasses and gels. By this formalism, we discuss the main kinetic features of the irreversible relaxation of simple liquids involved in the arrested spinodal decomposition of suddenly and deeply quenched. At some lower temperature we identify, by means of a latency time within which particles retain a finite apparently stationary mobility, the crossover from full phase separation to arrested spinodal decomposition which leads to recognize the onset of gelation.

Résumé :

The paper discusses the laws behind the filtering procedures of process liquids through porous materials. At metalwork finishing operations, the use of cutting fluids is of particular importance. During operation, liquids are continuously and intensively contaminated with solid metal parts. To restore the original properties, process fluids are cleaned of mechanical admixtures. The most widely used methods for purifying process liquids are those by filtration. The use of filtration for the purification of process fluids is most effective, since filtering through a layer of porous materials results in complete extraction and removal of solids from liquids. However, the structural features of the pores in the porous environment trigger a number of specific phenomena that arise when liquids move in the porous channels of a porous medium. The research purpose is to discuss and establish the laws behind the filtering procedures of process fluids through porous materials. When filtering process liquids through a layer of porous materials, the porous medium of the filter membrane expands with a change in porosity. The change in porosity occurs due to a decrease in the pore volume of the porous environment, since the solid parts together with the liquid penetrate into the porous channels of the porous environment and hover in them. The conducted studies permitted the authors to identify and study the laws of the filtering process and establish the law of change in porosity of the porous environment. Based on the established law, a differential equation is derived. It allowed, for given initial and border-line conditions, stating the problem of filtering the liquid through a layer of solid particles of a variable porous medium of the filtering membrane. The solution of the non-stationary problem with initial and border-line conditions by the finite difference method allowed determining the hydrodynamic parameters of fluid filtration through a layer of particles of the porous environment of the filter membrane and to obtain a solution of the non-stationary boundary problem of fluid filtration in a deformed porous medium. The use of research results promotes complete clarification of the process fluid and thorough removal of the solid parts of valuable secondary raw materials of metal processing, in particular for powder metallurgy, facilitates the launching of waste-free production, and increases the level of environmental cleanliness in the operating area of cutting fluids.

This article presents some selected results of the research on the slide porous bearings, sintered from the iron powder Höganas NC.100.24, with 2.5% of copper addition by weight, impregnated with selected ionic liquids, through comprehensive and detailed research works [L. 1–6]. The research was carried out within the framework of PBR/15-249/2007/WAT-OR00002904 Research Project financed by the Ministry of Science and Higher Education, during 2007–2011 [L. 7]. Several times higher load capacities and durabilities were obtained in comparison with standard ø25/ø35×20 mm sleeves lubricated with previously used oils, including perfluoropolyether oils. To date, there were no bearings sintered from the iron powder and impregnated with ionic liquids. The durability and load capacity of such bearings are higher, and that is why it was decided to submit a proper patent claim to the Polish Patent Office [L. 8].

Résumé :

Interfacial phenomena at a surface of porous and highly disperse adsorbents in the systems containing strongly and weakly bound and unbound liquids depend strongly on the confined space effects. These effects as well as the temperature behavior of liquids located in pores or voids between nanoparticles depend on many factors. They are the pore size distributions, pore volume, specific surface area, surface chemistry of adsorbents, chemical structure and molecular sizes of adsorbates, accessibility of pores vs. probe molecule sizes, as well as textural instability of adsorbents. This instability can appear, e.g., as compaction of fumed oxides under action of liquid adsorbates, especially water, or due to mechanochemical activation. The aim of this study is to analyze features of the interfacial phenomena upon interactions of fumed oxides (silica, alumina, alumina/silica/titania) and porous silicas (silica gels and precipitated silica) with polar (water, dimethyl sulfoxide), weakly polar (chloroform), and nonpolar (n-decane, aromatic benzene and toluene) liquid adsorbates depending on the morphological and textural characteristics of the adsorbents, various adsorbate characteristics, and temperature. The observed effects as well as related phenomena are important because they can differently influence the efficiency of practical applications of adsorbents under various conditions (temperature, pressure, concentrations) depending on the characteristics of adsorbents and adsorbates (liquids, solvents and solutes).

Résumé :

The behavior of fluids confined in porous materials has been of interest to engineers and scientists for many decades. Among the applications driving this research are the use of porous membranes to achieve liquid-liquid separations and to deionize water, the use of porous materials as beds for catalysis, and the need to extract liquids (especially oil and water) from such media. Many of these applications depend on transport, which is governed by flow or diffusion in the imbibed fluids. Both the flow and diffusion of multiphase fluids in porous media, however, strongly depend on the morphology of phase-separated domains, and on the kinetics of domain growth. Thus, it is worthwhile to study the behavior of multiphase fluids in porous media in the absence of flow. Recently, much attention has focused on even simpler systems that still capture these essential features, namely, near-critical binary liquid mixtures and vapor-liquid systems in model porous media, such as Vycor and dilute silica gels. Although near-critical fluids may seem rather artificial as models for multiphase liquids, there are several advantages associated with them. In general, domain morphology and growth kinetics are governed primarily by competition between interfacial tension and the preferential attraction of one phase to the surface of the medium. In near-critical fluids, the relative strength of these two energy scales is sensitive to temperature, and can therefore be altered in a controlled fashion. In addition, the kinetics of domain growth are sensitive to the temperature quench depth, and can be controlled.

Résumé :

Motion of variable viscosity water drop in perfect soil model is viewed. Resistance forces are presented as amount sum of mass forces and forces depending on water drop speed and liquid viscosity. Resistance forces are ranged in accordance with coordinate and time. Three terms in each range are holded - quadratic terms are presented. It was shown that in this case the equation of the motion has the form of the Riccati equation. The equation factors have been defi ned experimentally. Mathematic model proves that in defi nes conditions water drop is stopped forming a slug.
