Solubility And Solubility Modelling Of Polycyclic Aromatic Hydrocarbons In Subcritical Water, Wen Hui Teoh Wh Teoh
Solubility And Solubility Modelling Of Polycyclic Aromatic Hydrocarbons In Subcritical Water, Wen Hui Teoh Wh Teoh
Wen Hui TEOH
A static analytical equilibrium method was used to measure the binary and ternary solubilities of anthracene and p-terphenyl in subcritical water between 393 K and 473 K, and at 50 bar and 150 bar. Temperature was found to have the most significant effect on the solubility of polycyclic aromatic hydrocarbons (PAHs) in subcritical water. The effect of pressure, and the combined effect of temperature and pressure on solubility were found to be insignificant, particularly when the range of pressure considered is relatively small. The solubilities of PAHs were found to be governed primarily by sublimation pressure, and only secondarily by …

Solubility Of Organometallic Complexes In Supercritical Carbon Dioxide: A Review, Wen Hui Teoh Wh Teoh, Mammucari Raffaela R Mammucari, Neil R. Foster Nr Foster
Wen Hui TEOH
The solubility of organometallic complexes and their solubility trends in supercritical carbon dioxide were reviewed. A number of thermodynamic models currently used to predict the solute-fluid behavior of organometallic complexes in supercritical carbon dioxide, and the advantages and limitations to these thermodynamic models, were also discussed.

Activated carbon is the most widely used adsorbent for wastewater treatment and water pollution control. Lignocellulosic precursors obtained from crops and fruits offer several advantages for synthesizing activated carbons due to its wide availability and their interesting physicochemical properties. In particular, biomass of plum kernel and jacaranda are alternative lignocellulosic precursors for activated carbon preparation. This study reports the application of Prunus domestica and Jacaranda mimosifolia biomass for the synthesis of activated carbons to remove commercial dyes (i.e., AB25 and methylene blue) and Pb2+ ions from aqueous solutions. Two different methodologies for the preparation of activated carbons were analyzed, namely, …

The adsorption of acid blue 25, Cd2+ and Zn2+ on a physically activated bituminous carbon and a phosphoric activated carbon from wood was studied using single and binary (dye/metal) solutions, at 30 °C and pH 5. Results showed a synergic effect of acid blue 25 in the adsorption of Cd+2 and Zn+2. Thus, the amount of metal ions adsorbed on both activated carbons increased with the initial concentration of acid blue 25. The effect was especially remarkable in the case of the adsorption of Zn2+ ions on the wood-based carbon. For this particular system, the metal uptake increased up to …

In this work, Cuckoo Search is introduced for performing phase equilibrium and stability calculations for the first time. Cuckoo Search is a population-based method that mimics the reproduction strategy of cuckoos. This meta-heuristics have been successfully used for solving some engineering design and optimization problems with promising results. However, this emerging optimization method has not been applied in chemical engineering problems including thermodynamic calculations. This study reports the application of Cuckoo Search and its modified version for phase equilibrium and stability calculations in both reactive and non-reactive systems. Performance of this nature-inspired optimization method has been analyzed using several phase …

The adsorption of Acid blue 25, basic blue 9, basic violet 3, Pb, Ni, Zn and Cd ions has been studied in single and dye–metal binary solutions using two mineral materials: Clinoptilolite (CL) and ER (Erionite). These zeolites were characterized by FT-IR spectroscopy; potentiometric titration and nitrogen adsorption isotherms at 77 K to obtain their textural parameters. Results indicated that ER has an acidic character and a high specific surface (401 m2/g) in contrast with the zeolite CL (21 m2/ g). Surprisingly, the removal of dyes was very similar for the two zeolites and they showed a considerable selectivity by …

The biomass derived from pecan nut processing (Carya illinoinensis) fro alimentary purpose, specifically the pecan shells were used in this work as a biosorbent of acid blue 74 (AB74), acid blue 25 (AB25) and reactive blue 4 (RB4). This biomass was characterized by ultimate and proximate analysis. FT-IR spectroscopy, X-ray diffraction and SEM/EDX. Adsorption studies were performed in batch and continuous systems and adsorption kinetics, isotherms and breakthrough curves were experimentally determined. Results obtained suggest that the calcium compounds occurring in pecan shells are responsible of the favorable adsorption of anionic dyes, specifically for the removal of AB74. Biosorption results …

In this paper, we have studied and analyzed the capabilities and limitations of seven stochastic global optimization methods to model mean activity coefficients of ammonium aqueous electrolytes using the electrolyte NRTL model. These stochastic methods are: simulated annealing (SA), genetic algorithm (GA), differential evolution (DE), particle swarm optimization (PSO), DE with tabu list (DETL), harmony search (HS) and bare bones PSO (BBPSO). Convergence characteristics and performances of these optimization methods have been tested and compared using different stopping conditions. Overall, our results indicate that SA, DETL and BBPSO offer better performance and promising convergence characteristics for solving parameter estimation problems …

An Improved Ant Colony Optimization Method And Its Application For The Thermodynamic Modeling Of Phase Equilibrium, Jorge A. Fernández-Vargas, Adrian Bonilla-Petriciolet, Juan Gabriel Segovia-Hernández
Adrian Bonilla-Petriciolet
Ant Colony Optimization (ACO) is a stochastic optimization method that emulates the indirect communication among the individuals of an ant colony. This multi-agent strategy has been used to solve optimization problems from engineering applications, especially for combinatorial problems. Although ACO seems to be effective for global optimization, only few ACO algorithms have been reported for solving engineering applications problems with continuous decision variables. In this study, a new continuous ACO algorithm, with feasible region selection, has been implemented and applied to perform thermodynamic calculations related to the modeling of phase equilibrium. In particular, the numerical capabilities of this ACO algorithm …
Semi-Empirical Correlation For Binary Interaction Parameters Of The Peng-Robinson Equation Of State With The Van-Der-Waals Mixing Rules For The Prediction Of High-Pressure Vapor-Liquid Equilibrium, Seif-Eddeen K. Fateen, Menna Khalil, Ahmed O. Elnabawy
Semi-Empirical Correlation For Binary Interaction Parameters Of The Peng-Robinson Equation Of State With The Van-Der-Waals Mixing Rules For The Prediction Of High-Pressure Vapor-Liquid Equilibrium, Seif-Eddeen K. Fateen, Menna Khalil, Ahmed O. Elnabawy
Seif-Eddeen K Fateen
Peng-Robinson Equation of State is widely used with the classical van der Waals mixing rules to predict vapor liquid equilibria for system containing hydrocarbons and related compounds. This model requires good values of the binary interaction parameter kij. In this work, we developed a semi-empirical correlation for kij partly based on the Huron-Vidal mixing rules. We obtained values for the adjustable parameters of the developed formula for over sixty binary systems and over ten categories of components. The predictions of the new equation system were slightly better than the constant-kij model in most cases, except for ten systems whose predictions …

Challenges And Prospects Of Processes Utilising Carbonic Anhydrase For Co2 Separation, Patrycja Szeligiewicz, Wojciech M. Budzianowski
Challenges And Prospects Of Processes Utilising Carbonic Anhydrase For Co2 Separation, Patrycja Szeligiewicz, Wojciech M. Budzianowski
Wojciech Budzianowski
This article provides an analysis of processes for separation CO2 by using carbonic anhydrase enzyme with particular emphasis on reactive-membrane solutions. Three available processes are characterised. Main challenges and prospects are given. It is found that in view of numerous challenges practical applications of these processes will be difficult in near future. Further research is therefore needed for improving existing processes through finding methods for eliminating their main drawbacks such as short lifetime of carbonic anhydrase or low resistance of reactive membrane systems to impurities contained in flue gases from power plants.
