Optimization of the Reaction Rate in the Photocatalytic Degradation of Sodium Lignosulfonate in a TiO2 Slurry Reactor: A Multivariate Study with Response Surface Analysis
Authors: Shoko E. , Diniz Costa J. C. Da , White E. T.
Published: August 2010

This report used a 23‐factorial design to investigate the dependence of the reaction rate in the photocatalytic degradation of sodium lignosulfonate on solution pH, substrate concentration and TiO2 catalyst dosage in a slurry reactor. The objective was to locate an optimum for the combination of these variables by using a suitable multiple‐linear regression model and to identify any interaction effects among the variables. The region of exploration selected for this study was: substrate concentration, 40 mg/L ‐ 60 mg/L; catalyst dosage, 15 mg/L ‐ 35 mg/L and pH, 4‐8. A first‐order linear regression model could not adequately be fitted to the rate data, and the analysis of variance revealed significant interaction effects between pH and substrate concentration as well as pH and catalyst concentration. The nature of these interaction effects is discussed in detail. When a second‐order model was fitted to the data, an adequate description of the empirical relationship between the reaction rate and the three input variables was obtained. Analysis of the stationary point on the second‐order response surface revealed the existence of a saddle point within the region of exploration from where two near‐symmetric regions of high reaction rate were identified. The implications of these findings for practical reactor design are discussed.
A Simple Mathematical Model of Batch Growth of Bacillus stearothermophilus in Various Dairy Fluids
Authors: Chen X. D. , Yoo J. A. , Nguang S. K.
Published: August 2010

In this paper, a simple mathematical model describing the entire process of batch growth of bacteria has been proposed. The essence of this model is a proposal of the use of the growth‐history‐dependent ‘carrying capacity’ or ‘stagnation’ live cell population in the conventional logistic growth model. The rationale of this model has been summarised, and the model has been tested using the new experimental data on B. stearothermophilus growing in three different liquids with dairy ingredients. Reasonable agreements between the predicted and the experimental results have been obtained.

Authors: He M. , Nguang S. K. , Li X. M. , Qin G. F. , Chen X. D.
Published: August 2010

A low cost optical on‐line biomass sensing system for fermentation processes is presented in this paper. The calibration curve of the sensor obtained by using cell cultures in tap water revealed a linear profile in the range 0.1–4.0 g/L. The sensor was shown to have a fast response time and was insensitive to the natural light. A good reproducibility was obtained between the optical sensor and cell dry‐weight method values.
Membrane Processing of Echinacea purpurea Herb Juice Extract
Authors: Hossain M. M.
Published: August 2010

An investigation was carried out to evaluate the feasibility of using an ultrafiltration membrane technique to concentrate polyphenolic acids in the juice of Echinacea herb plant materials. The processing was conducted using a commercially available ultrafiltration membrane of 5kD MWCO (Pellicon XL50, Millipore, U.S.A and Sartocon Micro, Sartorius, Germany). Initial trials with the Echinacea herb extracts obtained from an industrial extracts company in New Zealand, showed that the permeate flux was low with the undiluted feed, and only 10–20% increase in concentration was possible. Several dilutions of the feed were needed to achieve an enrichment of more than two times. The dilution also resulted in a significant increase in flux and percentage recovery of the desired components, e.g. polyphenolics. The processing was done with freshly squeezed juice of Echinacea herb plant material (tops and stalk) harvested from Rewa Herb, Rangitaiki, New Zealand. With this feed in undiluted form, the permeate flux was higher but the percentage recovery of the polyphenolics was lower.
Removal of Ferriccyanide using Micellar Enhanced Ultrafiltration (MEUF)
Authors: Baek K. , Yang J.‐W.
Published: August 2010

Cyanides are used in a number of chemical synthesis and metallurgical processes (as simple salts or cyanide complexes). As a class, cyanides are highly toxic and must be destroyed or removed from wastewaters prior to being discharged. Micellarenhanced ultrafiltration (MEUF) involves the addition of a surfactant above the critical micellar concentration in order to entrap small solutes in solution. The increased hydrodynamic size of the solutes enables their rejection by polymeric ultrafiltration membranes. Solute rejection and permeate flux depend on solute and membrane characteristics. MEUF‐based separation of Fe(CN)36‐ using regenerated cellular acetate membranes was studied in order to assess the potential of MEUF for the remediation of wastewater polluted with ferriccyanide. The solute rejection coeflcient of ferriccyanide increasedfiom 59 % to 81% and to 99.9% as the molar ratio of cetylpyridinium chloride to ferriccyanide increased from 1 to 2. and 2 to 3, respectively, at a ferriccyanide concentration of 1 mM. The rejection coefficient of ferriccyanide increasedfiom 78 % to 99.9 % as the molar ratio increasedfrom I to 3 at a ferriccyanide concentration of 5 mM. The permeation flux and permeation of surfactant molecules across the membrane were evaluated in relation to the experimental conditions.
Real‐Time Control and Identification of a Thermal Process Based on Multiple‐Modeling Approach
Authors: Aminzadeh A. , Safavi A. A. , Khayatian A.
Published: August 2010

This article presents implementation of Real‐Time Control and Identification algorithms based on a Multiple‐Modeling approach for an experimental thermal process. The thermal process is a nonlinear plant; therefore, based on variations of the input and disturbance, four local operating regimes are defined. The linear local ARMAX models are identified for different regimes and integrated into a NARMAX model by combining them via proper validity and interpolation functions. Results of modeling the plant with a single model and multiple models show superior performance of the Multiple‐Modeling technique which is also more flexible. Moreover, the Real‐Time Control of the plant with four locally designed controllers is addressed. The platform used for the Real‐Time implementation is Matlab/Simulink/Real‐Time‐Workshop with Visual C++ and Watcom compilers using a DAQ interface. The Real‐Time application of the global controller based on the Multiple‐Model approach demonstrates excellent performance for this design when compared to a single PID controller.
Latency Reduction for Telerobotic Applications
Authors: Stemmer Ralf , Nagel Dirk , Drüe Siegbert
Published: August 2010

This paper tackles the problem of reducing the latency in telerobotic applications. The time delay between an action of the human operator and the corresponding reaction of the system has a negative impact on the synchrony, disturbs the operator's immersion, and yields adverse effects like simulator sickness or kinetoses. In this context we present an application to control a stereo camera system by measuring the operator's head motion. To decrease the latency, the head motion is described as Gauss‐Markov model and predicted with a Kalman filter. This estimation provides a reduction of the mean orientation error by 70% and the maximum error by 50% in contrast to an unpredicted control of the vision system. Experiments with subjects showed an improved compatibility due to the reduced latency.
Robustness of Model Predictive Control for Ill‐Conditioned Distillation Process
Authors: Minh Vu Trieu , Afzulpurkar Nitin
Published: August 2010

This paper briefly reviews controlling an ill‐conditioned distillation process and some basic computational algorithms of model predictive control (MPC). A modified MPC for ill‐conditioned distillation process with output regions is developed to improve the robustness of the controller for holding input and output constraints and rejecting disturbances. Compared with the traditional method of MPC for an ill‐conditioned process that deletes some controlled variables, the modified method with output regions proves its superiority because it still maintains penalty on the output deviation from the desired region into its controlled objective function.
Robust H∞ Non‐Fragile Controller Design for Uncertain Descriptor Systems with Time‐Varying Discrete and Distributed Delays
Authors: Yue Dong , Han Qing‐Long
Published: August 2010

This paper is concerned with the design problem of non‐fragile H∞ controller for uncertain descriptor systems with time‐varying discrete and distributed delays and controller gain variations. The designed controller is shown to be robust not only to parameter uncertainties, but also to errors in the controller coefficients. The obtained criterion to derive an efficient non‐fragile H∞ control design is expressed as a set of nonconvex matrix inequalities, which can be solved by combining both linear matrix inequalities technique and come complementarity method. A numerical example is given to demonstrate effectiveness of the proposed methods.
LMI Approach to Guaranteed Cost Control for Networked Control Systems
Authors: Li Shanbin , Wang Zhi , Sun Youxian , Yu Li
Published: August 2010

This paper addresses the time‐varying but bounded delay issue of networked control systems (NCS) within the framework of a discrete‐time linear state‐delayed system with norm‐bounded uncertainty. A delay‐dependent sufficient condition for the existence of a guaranteed cost controller for NCS is presented by a new Lyapunov‐Krasovskii functional. The condition is formulated as a set linear matrix inequalities (LMIs). The resulting controller can not only asymptotically stabilize the system but also guarantee an adequate level of performance. Theoretical analysis and simulation results show that the control strategy presented in this paper is effective and feasible.
The Importance of the Heterogeneous Reactions in the Formation and Destruction of NOx from Char Combustion
Authors: Feng B. , Zheng C. G. , Zhou Y. B. , Okazaki K.
Published: August 2010

This paper presents a theoretical study of the NOx behavior in a char‐NO‐N2‐O2 system in order to assess the importance of the gas‐solid reactions on NOx emission using a model described by Feng et al. (1997). The results show that gas‐solid reactions can be important in the NO destruction in the cases of both fuel‐lean and fuel‐rich conditions, depending on the heterogeneous reaction rates. The reaction of NO with char does not appear to be important if Levy's rate is applied. However, the reaction becomes important if Chan 's reaction rate is applied. Levy's rate has been used frequently in CFD codes and the heterogeneous reactions have been thought to be unimportant when using Levy's rate. This study shows that the heterogeneous reactions may be important if the reaction rate of NO with char increases.
Mechanisms of Submicron and Residual Ash Particle Formation during Pulverised Coal Combustion: A Comprehensive Review
Authors: Yu D. , Xu M.H. , Liu X. , Huang J. , Li G.
Published: August 2010

Coal fly ash has been a traditional concern of utilities since coal was used to generate electricity because it may bring about a number of technical and economic problems such as slagging, fouling, corrosion, erosion, waste disposal and overall boiler efficiency reduction. Moreover, fine particulates that escape the combustion system are recognized to have a negative impact on health and the environment due to the enrichment of the toxic trace elements and being readily inhaled. This work gives a brief review of the studies carried out in the past decades and tries to elucidate those processes that contribute to ash formation. They include the mechanisms that control submicron ash formation and those that are related to residual ash formation. The mechanism of vaporization and condensation is believed to be the major source of submicron ash particles and is discussed in detail in this review. Residual ash formation is the consequence of the competition between ash coalescence and char fragmentation. Moreover, fragmentation of excluded minerals and rotationally induced shedding may also contribute to the residual ash formation. Our literature review has provided a number of experimental and theoretical results describing how the submicron ash and residual ash are formed, Finally we present some recommendations for possible future research topics, including sampling techniques, measurement techniques, experimental studies and modelling efforts.
Purification and Characterization of Thermostable α‐Amylase from a Newly Isolated Thermophilic Bacillus stearothermophilus GRE 1
Authors: Zakir Hossain S.M. , Haki G.D. , Rakshit S.K.
Published: August 2010

A thermophilic bacterium, Bacillus stearothermophilus GRE 1, isolated from an Ethiopian hyperthermal spring produced a thermostable α‐amylase. Enzyme production in shake flask experiments while using optimum nutrient supplements and environmental conditions was 2.35 U/ml. Under optimized conditions in a bioreactor, 5‐6 fold higher enzyme activity was obtained than that of a shake flask. Gel filtration chromatography yielded a purification factor of 33.62‐fold and a recovery of 46.52%. The optimum temperature for activity was determined to be 60‐70d̀C and optimum pH was in the range of 5.5‐6.0. The enzyme maintained 50% of its original activity after 45 minutes of incubation at 80d̀C, and is stable at pH values of 5.0‐9.0. Enzyme activity was strongly inhibited by Cu2+, Zn2+ and Fe2+. The enzyme is calcium independent and 94% and 86% relative activities were displayed with low concentrations of Co2+ and Mg2+, respectively.
Mechanical, Physical and Antimicrobial Characterization of Edible Films Based on Alginate and Chitosan Containing Garlic Oil
Authors: Pranoto Yudi , Rakshit Sudip Kumar , Salokhe Vilas Mahadeo
Published: August 2010

Antimicrobial edible films based on alginate and chitosan were made by incorporating garlic oil (GO) as a natural agent. With incorporation of GO up to 0.4% there was a decrease in tensile strength and elongation at break, and slight increase in water vapor permeability. Alginate and chitosan films containing GO at levels of 0.2% and 0.1%, respectively are shown to have an inhibitory effect on Staphylococcus aureus and Listeria monocytogenes by using agar diffusion assay. However, when pieces of the film were added into liquid culture of indicator organism, it was found that the GO‐incorporated alginate film exhibited inhibitory activity against Staphylococcus aureus and Listeria monocytogenes, while chitosan films inhibited all three indicator bacteria. The micrographs show the GO is distributed throughout the matrix and indicate that the change in physical characteristics leads to the changes in mechanical properties and water vapor permeability. These results confirmed that GO has good potential for incorporation into edible films for food applications.

Authors: Azwar  , Hussain M.A , Ramachandran K.B.
Published: August 2010

This paper presents the results of a modeling and simulation study of an activated sludge process in a sequencing batch reactor (SBR), with emphasis on total nitrogen removal. This study focuses on the effect of dissolved oxygen (DO) and the phase length of aeration on the effluent chemical oxygen demand (COD) and nitrogen removal in SBR, so that the effluent COD and nitrogen removal can be maintained at the desired values. Simulation results show that operation of a SBR can be optimized by adjusting the DO set point, and that there is a close relationship between the DO concentration and respiration rate.
Minimum Wetting Rates for Falling Films on Stainless Steel
Authors: Morison K. R. , Tandon G.
Published: August 2010

The minimum wetting rate is defined as the minimum mass flowrate per unit circumference that is required to maintain of complete falling film of liquid on a surface. In this work minimum wetting rates in a 48 mm i.d. stainless steel tube were determined jor water, 50% sucrose solution, and reconstituted skim milk under isothermal and heat transfer conditions. It was found that initial distribution of the liquid at the top of the tube was critically important. The minimum wetting rates under isothermal and heat transfer conditions ranged from 0.22 kg m−1 s−1 for 50% sucrose at 20% to 0.12 kg m−1 s−1 for water az 70°C. Nearly all rates decreased with temperature. Equations in the literature did not accurately predict the results obtained.
Evaluation of New Adsorbents and Parametric Analysis for Determining Effectiveness in Sugar Decolourisation
Authors: Games V. G. , Hayashi J.
Published: August 2010

For a sustainable process, efficient materials and processes must be employed. Batch experiments were used to study the effect of various operating parameters such as the sugar concentration, temperature, adsorbent dose, and pH. In addition, determination of adsorption isotherms and pe∼ormancevaluation of two types of activated carbon, a commercial PICA and a new Maxsorb 3000 activated carbon. An increase in temperature resulted in an increase in the decolourisation rate. Furthermore, the amount of colourants removed, signlficantly increased with the amount of activated carbon; however the efficiency of decolourisation decreased. A 400% increase in activated carbon resulted in a 50% increase in decolourisation. Tests showed that a low pH strongly favours the removal of high molecular weight (HMW) colourants, while basic conditions slightly favour the removal of low molecular weight (LMW) colourants. The in‐situ sorption isotherms measured showed that the new activated carbon is superior to the widely used commercial activated carbon.
Growth Kinetics of Manganese Sulphate from Heating and Salting‐out Batch Crystallisation
Authors: Safaeefar P. , Ang H. M. , Tad? M. O. , Reyhani M.
Published: August 2010

Manganese sulphate crystals can be produced in laboratory‐scale batch crystallisers by either heating or by salting‐out crystallisation. However, manganese sulphate produced through heating forms monohydrate while salting‐out mode will form the tetrahydrate. The effects of various operating conditions including supersaturation, temperature and seed dosage on growth rate of these hydrates were studied. The crystal size distribution of manganese sulphate crystals was determined by Malvern Mastersizer laser diffraction and by using a Nikon microscope with digital camera attached. The growth rate was determined from the time shft of the crystal size distribution expressed in population density numbers and by the moments method. The measurements of the growth of the crystals from ex situ microscopy supported the calculated growth rate. Salting‐out crystallisation resulted in relatively large cubic crystals, and their size and size distribution can be improved by careful control of the operating conditions. However, heating crystallisation produced irregular crystals where controlling the operating conditions has little effect on the final crystal size and size distribution with almost no observable growth.

Authors: Zhong Liang‐Cai , Lei Zhe‐Long , Ji Chen‐Xi , Zhu Ying‐Xiong , Jiang Mao‐Fa , Chen Jun‐Ying
Published: August 2010

Optimizing experiments for the bottom tuyere configuration and blowing parameters of the 120 tonne top and bottom combined blowing converter at Shaoguan Iron & Steel Co. were carried out in a reduced‐scale water model. Results showed that the former configuration with 6 bottom tuyeres in the converter was not suitable with bath stirring because of the two tuyeres arranged in 0.33D pitch circle which caused the cavity deformation and stirring energy loss. Ideal bath stirring in the converter was obtained by using a new arrangement with 4 bottom tuyeres, two being in 0.57D pitch circle and the other two in 0.42D pitch circle. The optimal blowing parameters of the converter with the new bottom tuyere configuration were 1.26 Nm3/h of bottom gas flow rate, 160 mm of top lance height, and 30.52 Nm3/h of top gas flow rate.

Authors: Zhu Miao‐Yong , Wu Yong‐Lai , Zheng Shu‐Guo , Chen Ya‐Xian , Huang Zong‐Ze
Published: August 2010

In this study, a mathematical model describing the three‐dimensional turbulent flow, heat transfer and inclusion behavior in continuous casting tundishes was developed. Numerical calculations were performed to study the characteristics of flow, heat transfer and inclusion behavior in a one‐strand tundish with/without flow control. The results show that it is necessary to employ flow control devices in order to improve the effectiveness of removal of nonmetallic inclusions in the tundish. Without flow control, the hot melt ascends and cooled melt descends and then recirculates back to the inlet along the bottom of the tundish. However, the phenomenon of temperature stratification occurs after the steel flow passes through the dam in the tundish. Inclusions with diameter greater than 30 m̈m can be removed in the tundish, and reasonable flow control devices will assist the removal of inclusions of size 20‐25 m̈m.

Authors: Wang Nan , Chen Min , Jin Ai‐Jun
Published: August 2010

A molten salt layer composed of PbO‐PbCl2 is formed when the vaporization rate of PbCl2 is slower than its formation rate. Kinetic analysis has been performed of the chlorination‐vaporization reaction of Pb‐oxychloride in the pyrometallurgical recycling process of dust and ash. Simulation calculations for the bulk diffusion have been carried out, and also by applying the quasi‐steady principle the profiles of relative chemical potentials, compositions, and mass flux across the molten salt as well as the intermediate compound layers of Pb‐oxychloride, have been obtained. For the chlorination‐vaporization reaction, the effects of temperature and Cl‐potential in the gas phase (log(P2HCl / PH 2O) have been evaluated.
A Mathematical Model of the Decarburization in UHP Electric Arc Furnace Charged with Hot Metal
Authors: Jiang Zhou‐Hua , Gong Wei , Wang Wen‐Zhong
Published: August 2010

A mathematical model is developed based on the reaction kinetics and mass balance to investigate the decarburization rate based on operational parameters of the UHP electric arc furnace charged with hot metal. Thus, the evolution of carbon content can be described accurately, and the carbon content at the end of melting can be controlled dynamically. The calculated results are in good agreement with the production data of a 150 ton DC‐UHP electric arc furnace. Simulated results show that the decarburization rate is proportional to the flow rate of oxygen at high carbon contents, to the square root of carbon content at intermediate carbon contents, and to the carbon content at low carbon contents. The decarburization rate, especially at low carbon contents, can be enhanced by bath agitation. For optimum operating conditions, less oxygen flow rate is required as the carbon content decreases.
Influence of Iron Ore Indirect Reduction on the Transfer Process in Porous Media
Authors: Li Ming‐Chun , Tian Yan‐Wen , Zhai Yu‐Chun
Published: August 2010

The solid material used in most metallurgical reactions can be considered as porous media consisting of the accumulated pellets. When the fluid flows through the porous media, various chemical reactions may occur between the fluid and solid matrix which have a significant effect on the transfer process in the porous media. Based on derivation of the overall rate formulation of the representative elementary volume (REV), a mathematical model describing the transfer process in the porous media was established. The model was tested numerically by applying the implicit formulation finite volume method. The predictions were validated by comparison with the experimental results and literature data. For the indirect reduction of iron ores, the influence of the flow rate, the particle size, reaction rate, the dimension of the reactor, and the ratio of the Thielet number to the Peclet number on the distribution of gas concentration and the solid conversion degree were analyzed.
Prediction of Multiphase Horizontal Pipe: Flow: A Reassessment: Part I: Evaluation of Two‐Phase Correlations: Part II: Pressure Drop Prediction in Three‐Phase Gas‐Oil‐Water Flows
Authors: Spedding P. L. , Benard E. , Donnelly G. F.
Published: August 2010

Prediction of two‐phase pressure drop using published correlations and a wide data base showed that no single correlation could predict across the whole range of possible flow patterns. Particular difficulty was found in attempting to predict the intermittent SI and BTS patterns. However, successful prediction was achieved for the St + RW, St + RW + D, D and A + RW patterns.

Two‐phase pressure drop predictive correlations were extended to the three‐phase situation. Detailed evaluation identified three correlations which gave reasonable prediction of intermittent flow pressure drop. An adaptation is presented that enhances the prediction of these correlations for three‐phase flow. The separated three‐phase patterns could not be predicted to an acceptable standard using these types of correlations.
