    Journal PapersJournal of Applied Research of Chemical-Polymer Engineering , Volume 4 , Issue 4, 2021 March 10, {Pages 21-Mar }

    Abstract

    In this research, the possibility of asphaltene separation from the vacuum tower residue using the low cost industrial solvents such as 402, 404, 406, and 410 was investigated. In order to separate asphaltene the IP143/01 and ASTM D 3279-07 separation methods were utilized. In order to find the optimal state of asphaltene precipitation, Design of experiments software with three factors of residence time, the solvent-to-feed ratio and the volume percent of 406 solvent to the total solvent of 406 and 410 were used. The results showed that the effectiveness of each parameter in precipitating the asphaltene attributed to the ratio of solvent to feed, the ratio of solvent 406 to total solvent, and the residence time, respectively and there was a

    Journal PapersColloid and Interface Science Communications , Volume 37 , 2020 July 1, {Pages 100297 }

    Abstract

    Industrial emulsions are among the responsible factors for serious destructive environmental issues. Surfactants are considered as the stabilizing agents functioned in the emulsions through different processes. In this study, the effect of natural clinoptilolite zeolite particles added to dodecane-in-water emulsion was evaluated by investigating the surfactant-zeolite interaction to find the features of zeolite to destabilize the emulsion. Zeolite particles are anticipated to have capabilities for interaction with the surfactants stabilized the emulsion, resulting in their adsorption on the surfaces of zeolite particles based on the corresponding surface characteristics. The measurements of surface tension and interfacial tension showed the

    Abstract

    In this paper, natural zeolite (clinoptilolite) was desilicated to remove water from diesel fuel. Optimization of desilication conditions was done using Design-Expert 7. 0. 0 software and using response surface methodology. The considered parameters are the concentration of sodium hydroxide solution and the temperature and time of the desilication process. After optimization of desilication process condition, the water sorption percentage was 95. 32% under the optimized condition, the concentration of sodium hydroxide solution 0. 47 molar, temperature 84. 05 C and time of 2. 42 hours. To carry out the process of water sorption from fuel, amount of 0. 5% w/v of the desilicated zeolite (5g zeolite/1000mL of the fuel) was mixed with diesel fue

    Gibbsian Thermodynamic Study of Capillary Meniscus Depth

    Journal PapersScientific Reports , Volume 9 , Issue 1, 2019 January , {Pages 657 }

    Abstract

    In the presence of gravity or other external fields, liquid surface curvature deviates from a spherical shape and the surface configuration can be found by numerical integration of the Young–Laplace equation and the typical initial point for integration is the apex of the interface. The meniscus shape in large Bond number systems, which have the central portion of the interface flattened, cannot be determined with the apex as the initial point for integration. Here we find the depth of capillary menisci by considering an initial point for integration to be at the three-phase-contact-line (TPCL) and evaluate the curvature at the TPCL by free energy analysis and inspect the effect of different parameters on the interface shape. A new parame

    Abstract

    In this paper, ultrasound-assisted extraction (UAE) of oil from Moringa peregrina seeds was studied and compared with the Soxhlet method. Based on the response surface methodology (RSM), the extraction process variables such as liquid-to solid ratio, ultrasound power, extraction time and temperature were investigated to achieve the highest yield. By screening these parameters, it was concluded that liquid-to-solid ratio (mL/g) and extraction time were the significant parameters for oil extraction from Moringa peregrina using ultrasound treatment. The best possible range for liquid-to-solid ratio (5–20 mL/g), extraction time (5–30 min), and optimum ultrasound power (348 W) as well as extraction temperature (30 ?C) was obtained ac

    Abstract

    Biodiesel is known as a prominent candidate for the replacement of fossil-based fuels since the sources of these fuels have been depleted in the past few years. The most convenient process to produce biodiesel is the transesterification of triglycerides with an alcohol in the presence of a suitable catalyst. At the end of the reaction, two liquid phases comprised of biodiesel (main product), glycerol (by-product) and unreacted alcohol are co-exist. Phase equilibrium study is a tool to design the equipment that involved in the biodiesel production and purification processes. In this work, biodiesel was produced through the transesterification of linseed oil with methanol. Afterwards, the liquid–liquid equilibrium (LLE) data were measured f

    Abstract

    Due to environmental issues, wastewater treatment is a main concern for most industries and providing access to clean and affordable water is one of the big challenges. Besides, industrial wastewater contains many pollutants, one of the most toxic contaminants is organics. Currently, zeolites are widely used as an adsorbent to remove such pollutants. This study examines a surfactant modified zeolite Y (SMZY), as an applicable solution, to get over this problem. Here, zeolite Y, synthesized from bentonite, is used as an adsorbent basis. Then, it is characterized by XRD, FTIR, BET, SEM, and TGA. Next, it is modified by hexadecyltrimethyl ammonium bromide (CTAB) surfactant in different concentrations. These SMZYs are used to adsorb organic con

    Modeling the Phase Behavior of Asphaltene+ Toluene+ Polystyrene Mixtures A Depletion Flocculation Approach

    Journal PapersEnergy & Fuels , Volume 30 , Issue 2, 2016 January 14, {Pages 904-914 }

    Abstract

    Mixtures of polystyrene + Maya and Athabasca pentane asphaltene + toluene split into two stable phases, one toluene + polymer rich and one toluene + asphaltene rich. This phase behavior was attributed to depletion flocculation, previously, and a Fleer-Tuinier based model was used to simulate the phase diagrams including one-phase to two-phase boundaries, tie lines, critical points, and relative phase volumes in the two-phase region. The distribution of asphaltenes between molecular and aggregated species and the variation of the mean size and size distribution of aggregated asphaltene species with global composition are not known a priori. This knowledge gap presents a key conceptual challenge. Consequently, the variation of the fraction of

    Role of Precipitating Solute Curvature on Microdrops and Nanodrops during Concentrating Processes: The Nonideal Ostwald–Freundlich Equation

    Fatemeh Eslami, Janet AW Elliott
    Journal PapersThe Journal of Physical Chemistry B , Volume 118 , Issue 50, 2014 December 8, {Pages 14675-14686 }

    Abstract

    The microdrop concentrating process, which is one of the manipulations in the microdrop platform of microfluidic technologies, is a useful technique, especially in biological applications. This process may encounter a solute precipitation within the droplet if the solute reaches its solubility limit. In the case of very small solid precipitates, the solid particle size will affect the solubility limit, and the Ostwald–Freundlich equation (OFE) describes this dependency. Including the OFE in analysis affects the design parameters for this type of system and the system’s thermodynamic stability. Here, by means of Gibbsian surface thermodynamics, we provide the thermodynamic description and stability analysis of this system considering the

    Journal PapersThe Journal of Physical Chemistry B , Volume 118 , Issue 13, 2014 March 25, {Pages 3630-3641 }

    Abstract

    Microdrop platforms in microfluidic technologies provide developments for the study of a variety of systems by means of micrometer sized fluids. Concentrating the solutes within an aqueous microdrop via slight dissolution of water into a surrounding organic phase is a process which has important applications in biological systems. In our previous work we described the thermodynamic equilibrium of this concentrating process for two types of solutes, those with limited and unlimited solubility, and investigated the role of temperature, the amount of organic phase, and the initial concentration of the solutes. It was found that, during the concentration process which is accompanied by microdrop shrinkage, for specific initial conditions the sy

    Abstract

    Droplets exist widely in our everyday life and various industries. Numerous studies have been done to explore droplet systems and among them Gibbsian surface thermodynamics is a powerful means to investigate these highly curved systems. Due to the development of modern technologies and the introduction of novel materials, new systems have arisen that require this type of investigation. Here we have chosen two multiphase droplet systems of recent interest: the first one is droplet nucleation on a soft substrate as a modern material and the second one is the microdrop concentrating process which is mainly used in microfluidic technologies.Gibbsian surface thermodynamics is a rigorous method to predict the behaviour of highly curved surfaces s

    Design of Microdrop Concentrating Processes

    Journal PapersThe Journal of Physical Chemistry B , Volume 117 , Issue 7, 2013 February 11, {Pages 2205-2214 }

    Abstract

    Concentrating solutes within aqueous microdrops is one of the processes that have been investigated recently in microfluidic systems. In order to design the process of concentrating solutes within microdrops more precisely, thermodynamic investigation of the process plays an important role. By knowing the equilibrium concentration and size of the drop, the magnitude of the driving force toward equilibrium will be determined which will help researchers to design such processes more accurately. Here, we have investigated the thermodynamic equilibrium of microdrop concentrating processes involving two kinds of solutes: glycerol as a solute with no solubility limit and sodium chloride as a solute with a solubility limit. It is found that the pr

    Thermodynamic investigation of the barrier for heterogeneous nucleation on a fluid surface in comparison with a rigid surface

    Journal PapersThe Journal of Physical Chemistry B , Volume 115 , Issue 36, 2011 August 18, {Pages 10646-10653 }

    Abstract

    When a vapor phase is in contact with a solid or nonvolatile fluid, under conditions where the vapor is thermodynamically metastable to condensation, a droplet may nucleate from the vapor either homogenously within the vapor phase, or heterogeneously at the solid or fluid substrate interface. The case where the droplet is thermodynamically favored to nucleate heterogeneously is the subject of this article. The heterogeneous nucleation of a sessile drop on a soft surface has been studied many times experimentally and theoretically. It has been observed experimentally that heterogeneous nucleation happens faster on a soft surface in comparison with a rigid surface. Here we use Gibbsian surface thermodynamics to provide a physical understandin
