    ABSTRACT: In this study, biological methyl mercaptide removal is investigated using the bacterium Thiobacillus thioparus in a fed batch bioreactor. In this process, methyl mercaptide is converted into elemental sulfur particles as an intermediate in the oxidation of methyl mercaptide to sulfate. The main product is sulfur at either low dissolved oxygen or high methyl mercaptide concentrations, and also more sulfates are produced at high dissolved oxygen. According to the reactions performed, a mathematical model is developed. The model parameters are estimated and the model is validated by comparison to experimental data. The results show that the proposed model is in a good agreement with experimental data. According to the experimental results and mathematical model, sulfate and sulfur selectivity are sensitive to the concentration of dissolved oxygen. For concentrations of methyl mercaptide 0.2 mmol L−1 in the bioreactor and dissolved oxygen of 0.5 ppm, only 14% of sulfide load is converted to sulfate while the figure is 60% at the same methyl mercaptide concentration and dissolved oxygen of 4.5 ppm. At high sulfide load to the bioreactor, the concentration of noneliminated methyl mercaptide increases, leading to higher sulfur particle selectivity and consequently lower sulfate selectivity.

    ABSTRACT: Link to the full text: The main objective of this study is to have and compare fundamental results related to application of forced convection drying of a small sample of 2.5 g and a bed of sludge weighting 250 g. Temperatures of the drying air varying from 80°C to 200°C, air velocity from 1 to 2 m/s and humidity varying from 0.005 to 0.05 kgwater/kgdry air are then applied. The experiments are performed for two different sludges; activated sludge (AS) and thermalized and digested sludge (TDS). The results, by observing the drying kinetics of the products and its temperature, show different behavior of the sludge during process performing. Correspondingly, three main phases are observed during bed drying, which are reduced to only two for drying small samples. Determination of parameters influencing the process shows that temperature of the drying air and origin of the sludge can profoundly influence the behavior of the sludge. The exergy analysis of the two parts of the drying system allows determining the optimum drying conditions for all sludges which are: 140 °C, 2 m/s, 0.05 kgwater/kgdry air, with an exergy efficiency attaining 90%.

    ABSTRACT: The adsorption of FD&C red 2 and FD&C yellow 5 onto chitosan films was evaluated by equilibrium isotherms, thermodynamics and kinetic studies. The effects of temperature (298–328 K), initial dye concentration (50–300 mg L−1), stirring rate (50–350 rpm) and contact time (0–120 min) were investigated at pH of 2.0 and 100 mg L−1 of chitosan films. The dyes concentration was determined by spectrophotometry. Freundlich and Langmuir models were used to represent the equilibrium data. The Langmuir model was the more adequate to represent the equilibrium data (R2 > 0.99 and average relative error <2.50%) and the maximum adsorption capacities were 494.13 mg g−1 and 480.00 mg g−1 for FD&C red 2 and FD&C yellow 5, respectively, obtained at 298 K. The RL values ranged from 0.044 to 0.145. The adsorption was exothermic, spontaneous and favorable. For the FD&C red 2, 90% of saturation was attained at 120 min and the Elovich model was the more appropriate. For the FD&C yellow 5, 95% of saturation was attained at 20 min and the pseudo first–order model was the more adequate to fit the kinetic data. Chitosan films were easily separated from the liquid phase after the adsorption process, providing benefits for industrial applications, and its application range can be extended for azo dyes.

    ABSTRACT: In this report, spectrophotometric, kinetic and structural analysis has been carried out for the formation of cobalt nanoparticles (CoNPs) using 4-aminophenol as reducing agent. The localized surface plasmon resonance band (SPR) of cobalt nanoparticles in the UV-vis spectrum is used to determine the rate of formation of cobalt nanoparticles and assess the beginning of the oxidation process. The effect of cobalt nitrate, 4-aminophenol and TTAB concentration was investigated on the growth rate of cobalt nanoparticles. CoNPs were characterized by means of UV-vis, field emission scanning electron microscope (FESEM) and energy dispersive spectroscopy (EDS). The data obtained in this work provide valuable information on the rate of reactions at the nanoscale.

    ABSTRACT: Densities ρ, ultrasonic speeds u and refractive indices, n for pure n-hexane, methylacrylate (MA), ethylacrylate (EA), ethylmethacrylate (EMA), butylacrylate (BA) and of their thirty six binary mixtures over the entire composition range were measured at 298.15, 303.15, 308.15 and 313.15 K. Using these data the excess molar volumes, VE, deviations in isentropic compressibilities, �ks, deviations in molar refractions, �Rm and deviations in internal pressure, �Pi were calculated for the mixtures at given temperatures. Apparent molar volumes, Vφ,2, and apparent molar compressibilities, Kφ,2 of acrylic esters in n-hexane were also calculated. Partial molar volumes, V0φ,2 and partial molar isentropic compressibilities, K0φ,2 at infinite dilution were estimated. Moreover, the optical property, partial molar refraction, R0φ,2, of the systems at infinite dilution were examined. The variations of these parameters and of the optical property suggest that the strength of interactions in these mixtures follow the sequence: MA < EA < EMA < BA.

    ABSTRACT: Magnetite (Fe3O4) and Zn0.5Fe0.5Fe2O4 nanoparticles (NPs) were synthesized via sonochemical coprecipitation reactions with moderate ultrasound irradiation. The structure and crystalline=particle sizes of the synthesized NPs were determined by X-ray powder diffraction (XRD) and transmission electron microscopy (TEM), and the magnetic properties were measured by vibrating sample magnetometry (VSM). The results show that NPs of smaller size and narrower size distribution can be synthesized via coupling of moderate ultrasound irradiation in coprecipitation reactions. In addition, magnetic NPs prepared in the presence of ultrasonic irradiation exhibit improved magnetic properties.

    ABSTRACT: Recently, due to an increase in production demand in nuclear and oil and gas industries, the requirement to migrate toward larger pipe sizes for future developments has become essential. However, it is interesting to note that almost all the research on two-phase gas–liquid flow in vertical pipe upflow is based on small-diameter pipes (D ≤ 100 mm), and the experimental work on the two-phase gas–liquid flow in large-diameter (D > 100 mm) vertical pipes is scarce. Under the above circumstances, the application of modeling tools/correlations based on small-diameter pipes in predicting flow behavior (flow pattern, void fraction, and pressure gradient) poses severe challenges in terms of accuracy. The results presented in this article are motivated by the need to introduce the research work done to the industries where the data pertaining to large-diameter vertical pipes are scarce and there is a lack of understanding of two-phase gas-liquid flow behavior in large-diameter (D > 100 mm) vertical pipes.The unique aspect of the results presented here is that the experimental data have been generated for a 254-mm inner diameter vertical pipe that forms an excellent basis for the assessment of modeling tools/correlations. This article (i) presents the results of a systematic investigation of the flow patterns in large-diameter vertical pipes and identifies the transition between subsequent flow patterns, (ii) compares it directly with the existing large- (150 mm) and small-diameter data (28 mm and 32 mm) in the same air–water superficial velocity range, (iii) exemplifies that the existing available empirical correlations/models/codes are significantly in error when applied to large-diameter vertical pipes for predictions, and last (iv) assesses the predictive capability of a well-known commercial multiphase flow simulator.

    ABSTRACT: Pressure distribution, caused by ultrasonic wave propagation, has the crucial effect on efficiency of sonoreactor for crude oil upgrading. In this study, acoustic pressure distribution was computed by numerical solution of acoustic wave propagation equation in crude oil sonoreactor. By analyzing of numerical simulation results, optimum geometrical and operational parameters, comprising type and probe size, probe depth in bulk of crude oil, dimensions, shape of reactor, frequency, and sound power, were discussed for the highest possibility of cavitation, chemical, and physical changes. Moreover, the effect of probe location on pressure distribution was investigated. The results show the important effect of probe location on pressure distribution due to change of wave reflection angles.
