Experimental study has been aimed at examining the flow regimes of gas–liquid in up-flow ejectors by planar laser induced fluorescence (PLIF) technology under air–water and carbon dioxide–water system, the velocity fields by particle image velocimetry (PIV) under carbon dioxide–water system and gaining the bubble photos under air–water system. The conclusions were as follows: (1) The PLIF experimental results showed that in the absence of swirl, the liquid formed and maintained jet in the lower part of ejector and the air flowed up around the liquid jet annularly. At some point along the ejector axis, the jet broke up and the gas dispersed into small bubbles in the liquid. In the presence of swirl, the liquid jet didn’t exist any longer and the two phases interpenetrated and diffused immediately when two phases contact each other. (2) In the PIV measurements, the experimental data showed that at steady state the gas bubbles in the liquid flowed up along the axial direction or paralleled to the wall without swirl. However, the existence of swirl makes the velocity vectors of gas bubbles rotated and flowed up with some extent helicity. (3) The bubble photos showed that at low G/L the bubbles in the presence of swirl form the bubble chain while in the absence of swirl the bubbles disperse uniformly. However, when the G/L ratio increases, the difference in the bubble distribution diminish and the bubble tend to fill of the whole diffuser of the ejector with and without swirl.

A mathematical model was developed to predict the particle size distribution (PSD) in a steady-state fluidized-bed granulator with selective withdrawal of large particles, and was confirmed through a series of experiments using sodium chloride and sodium sulfate as bed materials. The model was extended from Kunii's PSD model, which was derived only for the backmix-flow fluidized-bed reactor where discharged particles have the same PSD as the materials in the bed.<BR>From batch experiments, operating windows that permit the growth mode to be coating were identified and used in steady-state fluidized-bed granulation experiments.<BR>The segregation factor of materials was obtained from a cold-bed segregation experimental apparatus where large particles were withdrawn selectively through a segregation boot. Using this segregation factor, the steady-state PSD was calculated by computer simulation. It was found from the simulation that as the input flow rate of seed particles increases, average particle size of bed material and output flow rate of grown material decrease.<BR>It was also demonstrated that the simulation results was in good agreement with experimental results obtained from a 10 cm-diameter steady-state fluidized-bed granulation system.

In the chemical industry, the components of the production process are 1) production plant personnel, 2) the production unit, and 3) the production support system (PSS). These elements are the sources of process resilience. Resilience refers to the capability to restrain the disruptive signals that occur inside and outside the production process. The resilience always changes and its deterioration invites various influences that disturb the production activities. Therefore, it is necessary to observe, maintain, and improve the resilience to maintain productivity. However, quantitative estimation of resilience has not been attempted yet, because estimating the resilience can be difficult. The reasons are 1) the sources of resilience are not clear, 2) the scale of estimation is not specific, and 3) the object to be restrained is not apparent. In this paper, a metric, criterion of measurement, and method for quantitative estimation of resilience in a PSS in the production process are proposed. The procedure to estimate the resilience is as follows. First, the skills of the production plant personnel are classified into three categories: operational, memory, and communication skills. Next, the work hours of production plant personnel in the daily routine are measured, and based on these data, the work hours devoted to each skill (WHDS) are estimated to obtain the value of the skills (VOS). The value of the skills is the criterion used to estimate the skill of the production plant personnel, and this value includes the level of the skills and the knowledge of the production plant personnel. As each function of the PSS is implemented instead of the skills of the production plant personnel, it is possible to obtain replaceable work hours devoted to the skills by PSS. Therefore, based on the level of the skills and knowledge replaced by the PSS in the daily routine of the production plant personnel, the resilience produced by the PSS can be estimated.

The products and the capacity of production in the production process in the chemical industry depend on the design specification of the units. And many disruptions exist on the production process. Therefore, a company that aims to maximize the profit from the operation of a production process needs to restrain the influence of disruptive signals, and the capacity of the production process to restrain their negative effects is called the resilience. To maintain productivity, the company must improve the resilience. In this paper, the authors propose a metric for the quantitative estimation of resilience based on the skills and knowledge of production plant personnel on the production process in the chemical industry using the value of skills estimated quantitatively by the real measured value of skills of production plant personnel working at the production process. The value of skills is composed of the proficiency (level of skills and knowledge) and the labor efficiency (work hours devoted to skills), and it is possible 1) to estimate the averaged resilience of a work team by the potential capability of production plant personnel to compare the resilience of several production process, and 2) to know the change or trend of resilience in a single production process. It is possible to evaluate the metric of resilience commonly no matter what kind of process or number of the production plant personnel.

The effects of a corona precharger on the performance of a fabric filter were studied experimentally in the air with controlled humidity. Test dusts, fine calcium carbonate and fly ash, were precharged and then introduced to a test fabric. The test fabrics were felt, spun staple and filament woven fabrics.<br> When charged dust is collected on a test fabric at low filtration velocity and low relative humidity, a rugged surface often appears on the charged dust layer, and pressure loss across the loaded test fabric is reduced. This electrostatic effect on pressure loss occurs not only for felt fabric but also for spun staple woven fabric, but does not appear for polyester (Tetron) and glass filament woven fabrics, because of pin-hole formation.<br> On the other hand, the collection efficiency of a fabric filter can always be improved by using a corona precharger. The collection efficiency increases with the charge-to-mass ratio of dust. Even if pin-holes are formed during the filtration, the collection efficiency can be improved using a corona precharger, without substituting a higher-performance fabric.

A new optical resolution method is proposed in which one enantiomer of a racemic mixture is replaced with a tailor-made additive, and the displaced enantiomer is crystallized. DL-Aspartic acid (Asp) was examined as a model racemic compound. First, L-Asp crystallization was examined in the presence of L-asparagine (Asn) or D-Asn. The effect of Asn was chirality-specific; L-Asn specifically replaced some of the L-Asp in the crystal lattice and solid solutions of L-Asp with L-Asn formed. Secondly, DL-Asp crystallization was examined in the presence of L-Asn, and the obtained crystals were solid solutions of DL-Asp with L-Asn partially replacing L-Asp in the DL-Asp crystal lattice. Finally, crystallization of the L-Asp in the filtrate of the DL-Asp crystallization in the presence of L-Asn was examined. The obtained crystals were a mixture of solid solutions of L-Asp with L-Asn and solid solutions of DL-Asp with L-Asn. Moreover, when D-Asn was added to the DL-Asp crystallization, a mixture of solid solutions of D-Asp with D-Asn and solid solutions of DL-Asp with D-Asn was crystallized from the filtrate. These results show that racemic compounds could be resolved by the proposed method.

Cofactor regulation for the production of reduced metabolites, such as ethanol, plays an important role in the metabolic pathways of microorganisms. In this study, the intracellular NADH/NAD+ ratio in the ethanologenic strain Escherichia coli KO11 was increased by the overexpression of formate dehydrogenase from Mycobacterium vaccae. To avoid the generation of pyruvate-derived byproducts, genes coding for the lactate- and acetate-producing pathways were successfully deleted using genome editing based on the CRISPR-Cas9 system. In the culture of the constructed strain, the NADH regeneration system increased the intracellular NADH/NAD+ ratio in the presence of formate, leading to enhanced ethanol production; the amount of ethanol produced was 36% more than that produced by the original KO11 strain in culture for 24 h. A detailed investigation revealed that the transient pyruvate accumulation plays a key role in the enhanced ethanol production using the NADH regeneration system.

<p>Micromixing characteristics of a tubular packed bed reactor with different packings were investigated by adopting the competitive parallel reaction, namely, the Villermaux–Dushman reaction. Better micromixing efficiency was achieved with the tube packed with Winpak® compared to that packed with Mini Ring or Mellapak™ or the empty tube. The segregation index (<i>X</i>_S) decreased as the volumetric flow rate increased, but increased with increasing volumetric flow ratio. Moreover, the micromixing time (<i>t</i>_m) was calculated using an incorporation model based on the experimental data. The minimum <i>t</i>_m value of the tube packed with Winpak® (<i>t</i>_m=1.54 ms) was less than that of the tube packed with Mini Ring (<i>t</i>_m=2.73 ms) or Mellapak™ (<i>t</i>_m=2.14 ms) or the empty tube (<i>t</i>_m=3.79 ms).</p>

This paper addresses ontologies of intentional and unintentional processes. Specifically, a methodology for developing processes ontologies is described. Typically, domain ontologies are developed in an ad-hoc fashion, without the reasons and justifications of the class structure. To resolve this issue, we propose a methodology based on Formal Concept Analysis (FCA) as a way to assist the development of a domain ontology. FCA is an analysis technique for knowledge processing based on applied lattice and order theory. The methodology is illustrated with the development of an explosion ontology.

In wastewater treatment plants (WWTPs), some variables such as BOD5 and COD that are related to effluent quality, are difficult to measure directly online due to technical or economic limitations. To deal with this problem, a soft sensor that is based on a deep neural network with a named stacked autoencoder (SAE) is developed for WWTPs. Neural networks with deep structure are superior to shallow ones when facing complex problems in modern applications, which makes them suitable for wastewater treatment processes. However, deep structures are difficult to train when using traditional learning algorithms, and there are no general guidelines for identifying the proper network structure for a specific application. In the present work, a deep learning technique called the greedy layer-wise training algorithm is employed to train a deep neural network, and a genetic-algorithm strategy is developed for identifying the number of neurons in each hidden layer. In order to demonstrate its usefulness, the proposed soft sensor is tested through the test-bed Benchmark Simulation Model No. 1 (BSM1) with different weather conditions. The results indicate that the proposed soft sensor based on a deep-structure neural network can achieve better prediction and generalization performance in comparison with commonly used methodologies.

An extractive fermentation for ethanol production was carried out by using immobilized cells of Saccharomyces cerevisiae Kyokai 7 and its lactose-fermentable fusant (strain PN13). Although o-isopropylphenol (OIPP) and o-tert-butylphenol (OTBP) as extractive solvents had relatively large partition coefficients against ethanol (1.4 by weight-based concentration), the solvents were heavily toxic to both yeasts. Some plant oils such as castor oil protected the yeasts from the toxicity of OTBP. Therefore, the ethanol fermentation became feasible even in the presence of OTBP as extractant by using yeast immobilized within alginate gel containing castor oil as protective agent. The ethanol production activity of gel beads containing the oil was not deteriorated through six repeated uses.

Global warming is a serious problem requiring immediate countermeasures. Large-scale afforestation in arid areas for the aim of absorbing CO2 is considered to be one of these measures and the research activities for it have been carried out in Leonora, Western Australia. In this study, the relationship between the biomass distribution and topographic features was examined in order to collect basic information for the selection of suitable afforestation regions in the research area using a biomass distribution map and some topographic elements. The results were as follows.(1) Plant growth is related to the movement of and the volume of runoff water derived from inequality of the ground, which leads to a biased distribution of nutrient accumulation and of surface soil thickness.(2) The total potential biomass estimated from the present topography is greater than the present biomass in the 30 km × 50 km research area. A mass of 319 kt-C could be absorbed in the research area without any improvements in the landform.(3) A substantial improvement on the environment utilizing vast arid areas by afforestation is necessary to fix enough carbon deterring global warming.

Recently, the control of non-CO2 greenhouse gases has attracted interest as a way to prevent global warming. Several research studies on the development and assessment of technologies to control CH4 and N2O emissions by human activities are under way. In the wastewater treatment field, the development of anoxic/oxic processes and the introduction of bacteria that effectively prevent N2O emission have been studied. Moreover, it has been clarified that eco engineering technologies such as artificial wetlands and soil trench systems are very effective, especially in developing countries. As for landfill disposal, CH4 oxidation by cover soil and the use of CH4 gas as a source of energy have very effectively reduced the emission of CH4. In the combustion field, it was clarified that N2O emissions vary according to the structure of each combustor and its operational conditions. And research and development concerning combustors and their optimum operational conditions are under way. Concerning automobile sources, characteristics of N2O emission from gasoline fueled vehicles installed with a catalyst were examined. Three way catalysts and so on are now being developed. Chemical industries, especially adipic acid production are another non-negligible N2O source, and cracking process related countermeasures have been applied. CH4 and N2O emissions from agricultural land are strongly dependent on the oxidation-reduction environment of soil and on fertilization, so they must be suitably managed. The development and management of ruminants feeding and suitable treatment of animal waste are very important ways to control CH4 and N2O from livestock. Research projects to improve the CH4 and N2O emission-absorption inventory, and to estimate the suitable technologies to control CH4 and N2O emission are now in progress. Combining these projects appropriately will develop technologies and systems and will make great contributions to the control of the emission of GHGs and to global warming.

A new hydrophilic method for achieving a high-performance adsorbent by impregnating silica into pores of activated carbon has been proposed. In the process, silica-gel was synthesized in the pores of activated carbon after inserting a sodium silicate solution into the pores. Three types of activated carbon were tested to produce hydrophilic activated carbon and to investigate the hydrophilicity by measuring the adsorption isotherms of water vapor and pore structure characteristics. The proposed method worked effectively for adding hydrophilicity to activated carbon, since all of adsorption isotherms of the material treated with this method shifted to a lower region of water vapor pressure than that of the raw material. The shift to a lower relative pressure of adsorption isotherm was maximum when the concentration of sodium silicate solution was 1 mass%.

Simulation of polymerization-induced phase separation of a polymer gel from a multifunctional monomer was carried out using the phase field method. To describe the driving force for phase separation, the interfacial energy between the polymeric phase and the aqueous phase was assumed to depend positively on the degree of polymerization, while the thickness of the interface at equilibrium and the mobility were assumed to depend negatively on it. The mobility was also assumed to depend negatively on the volume fraction of the polymer. A sigmoidal function was introduced to describe the nonlinear dependence of the mobility on the volume fraction. The wavelength of phase separation became finer as the polymerization rate increased when the rate of the reaction had a time scale similar to that of diffusion. When a nonreactive polymer coexists in the phase separation, the wavelength of phase separation shrinks because of suppression of diffusion caused by the coexisting polymer. These results qualitatively agreed with the experimental results for macroporous silica prepared via polymerization-induced phase separation.

Intraparticle distribution of adsorbate amount in cyclic adsorption and desorption is simulated by two methods: rigorous numerical solution of the particle-phase diffusion equation and the linear driving force (LDF) approximation. It becomes clear that the conventional value of 15 <i>D</i>_s/<i>R</i>² as the intraparticle mass transfer coefficient, <i>k</i>_s<i>a</i>_v, in the LDF method is not advisable for the simulation of transient adsorption and desorption. A mass transfer coefficient defined by including the cycle time is thus proposed. In this new conception, <i>k</i>_s<i>a</i>_v increases with decreasing cycle time and approaches π²<i>D</i>_s/<i>R</i>² with increasing cycle time. Simulations of cyclic mode by the LDF method using this new <i>k</i>_s<i>a</i>_v agree well in the steady state with that obtained by numerical solution of the diffusion equation. In unsteady-state operation, however, the two simulations do not coincide with each other because of overestimation of driving force for adsorption and underestimation for desorption in the LDF method.

Heat evolution rate curves were recorded with KBrO₃-quiet supersaturated aqueous solution at constant cooling temperature, <i>T</i>, by using a differential scanning calorimeter and were analyzed on the basis of the growth rate of all crystallites pre-formed in the sample solution. Taking microscopic observation into account, the expression of the overall growth rate, <i>R</i>, was derived, on the assumption that the crystallite surface is Kossel''s and that its growth rate is determined by two-dimensional nucleation rate, <i>J''=k₁''S^m''</i>.<br> <i>R=βhAJ''≈k₁"(C₀-C)^2/3S^m''</i> (1)<br>where C, C₀ and S are concentration at <i>t=t</i> and =0 and supersaturation ratio, respectively. <i>m''</i> is number of solute in a critical nucleus and is not constant, but depends on <i>S</i> and <i>T</i>.<br> The values of two-dimensional nucleation parameters (<i>m''</i> radius, free edge energy σ'' and surface energy estimated from σ'' and activation energy) were of reasonable order of magnitude. Comparison of these values with those of the three-dimensional parameters obtained previously is discussed. It may be concluded that Eq. (1) and hence the expression for <i>J''</i> proposed in this paper are adequate for the growth rate and two-dimensional nucleation rate, respectively.

An experimental investigation is carried out for natural-convection heat transfer to air from an array of five cylinders which are arranged in an inclined plane. The heat transfer coefficient of each cylinder in the array and the average heat transfer coefficient of the array are obtained for a variety of combinations of cylinder spacing, cylinder surface temperature and array inclination angle.A correlation equation for the average heat transfer coefficient of the vertical array is proposed. A method for estimating the heat transfer coefficient of each cylinder in the array is also given. Application of these results and the previously proposed heat transfer correlations for the horizontal array shows good agreement with the heat transfer coefficient of each cylinder in the inclined array.

The activity coefficients of HSO3– and H+ were determined in concentrated aqueous solutions of NaCl in order to provide a theoretical basis for using sea water as a solvent in flue gas desulfurization processes.The activity coefficient of HSO3– was determined at 313 K and 323 K by measuring the pH of mixtures of NaCl, H2O and small amounts of NaHSO3 at a known partial pressure of SO2. The activity coefficient of H+ was determined over a temperature range of 296 K–333 K by measuring the pH of mixtures of NaCl, H2O and small amounts of HCl.As the ionic strength increased, the activity coefficient of HSO3– decreased while that of H+ increased. The Pitzer Equation could correlate the activity coefficients of both species with reasonable accuracies for practical use.

The International Symposium on Innovative Materials for Processes in Energy Systems, IMPRES, organized by IMPRES Committee and the Division of Energy Engineering, the Society of Chemical Engineers, Japan (SCEJ), was held at Kyoto Research Park, Kyoto on 28th to 31st October, 2007. The symposium was designed to aid in the establishment of a sustainable energy society by catalysing the development of innovative energy materials. The symposium concept owes a part of its origin to an energy road map project which was discussed by a project group in the Division of Energy Engineering, SCEJ (Kameyam and Kato, 2005; Kato, 2007). The road map named HONEBUTO Energy Road Map was based on chemical engineering technologies, and attempted to investigate the shape of an ideal energy society in the future. The authors of the group realized the importance of innovative energy materials for the realization of such a society from the discussion. Although innovative materials are developing now in any technology fields, material developments in energy fields are still needed and such development would benefit from a systematic approach. This symposium, IMPRES, is aimed at responding to such needs. (See more in PDF.)
