    ABSTRACT: The flow behavior and particle motion in a pulsed gas-solid spouted bed was investigated using the Eulerian-Lagrangian approach. The Computational Fluid Dynamics-Discrete Element Method (CFD-DEM) was used to evaluate the gas flow field and particle trajectories. The model was four-way coupled to account for fluid-particle, particle-fluid and particle-particle interactions. A column of 150 mm × 15 mm cross-section and height 750 mm containing 24,500 particles of diameter 2.5 mm was investigated. Gas entered through a 10 mm × 15 mm slot at the base of the bed. Steady spouting was compared with pulsed spouting at frequencies of 1, 4, and 10 Hz, with superficial velocity amplitude of 0.5 and 1 m/s, and a mean superficial spouting velocity of 2 m/s. In addition to comparing the bed pressure drop versus time and its Fourier decomposition, the hydrodynamics in the spout and annulus regions were examined. A new procedure was introduced to assess spouted bed mixing and homogeneity. Flow pulsation was shown to provide stronger upward air momentum, less horizontal gas percolation, better circulation, higher downward particle flux near the sidewalls, better mixing and greater homogeneity.

    ABSTRACT: The CO2 solubility in N-ethylmonoethanolamine (EMEA) solutions was investigated using the vapor-liquid equilibrium (VLE) and the absorption-desorption apparatus. A tertiary amine, N, N-diethylethanolamine (DEEA), was used as a novel solvent, and other non-aqueous solvents, diethylene glycol, triethylene glycol, benzylalcohol, n-butyl alcohol and polyethylene glycol-200 were used for comparison. The EMEA + DEEA solution displayed a much higher CO2 solubility than other non-aqueous solutions though lower than the EMEA + H2O solution in the VLE experiment. However, the EMEA + DEEA solution exhibited a higher cyclic absorption capacity than EMEA + H2O solution in the cyclic absorption-desorption experiment. The reaction mechanism of EMEA + DEEA + CO2 was investigated by 13C NMR spectroscopy, which indicated that the non-aqueous solvent of DEEA participated in the chemical absorption of CO2, and thus improved the CO2 solubility. The tertiary amine DEEA used as non-aqueous solvent shows more excellent performance than alcohols and glycols.

    ABSTRACT: In this work, we develop low dimensional models to describe steady state mass transfer and reactions in two-phase stratified flow in microchannels. The partial differential equations that consider the effect of axial convection, transverse diffusion and reaction are averaged in the transverse direction using the Lyapunov-Schmidt method. The resulting reduced order model describes the evolution of the cup-mixing average and cross-section average concentrations along the axial direction. Two different reduced models are obtained: a One Equation Averaged model (OEA) in which we average across both fluids simultaneously, and a Two Equation Averaged model (TEA) in which we average across each fluid separately. The OEA model cannot capture the initial mass transfer between the phases when they first come into contact at the inlet of the channel. It can only be used when there is a deviation from equilibrium due to a reaction. The TEA model overcomes these limitations and is able to describe mass transfer between the phases right from the inlet of the channel. It accurately predicts extraction and reactive extraction with slow reactions. However, if the reaction is fast, the TEA model fails and the OEA model is preferable. Some applications of the TEA model are presented. It leads to closed form expressions for the overall mass transfer coefficient in terms of the properties of the fluids and their holdups. An analytical solution of the TEA model is derived for the case of non-reactive extraction and used to identify the operating conditions for high extraction performance. Finally, the TEA model is applied to investigate how the yield in competitive-consecutive reactions can be improved by exploiting the mass transfer resistance between the two phases.

    ABSTRACT: Gas flow-through microcalorimetry has been applied to study the Pd/Al2O3 type catalysts in the exothermic hydrogen recombination process: H2 + O2 → H2O, in view of the potential application in the passive autocatalytic recombination (PAR) technology. The flow mode experiments revealed thermokinetic oscillations, i.e., the oscillatory rate of heat evolution accompanying the process and the corresponding oscillations in the differential heat of process, in sync with oscillatory conversion of hydrogen. Mathematical evidence has been found for the deterministic character of the aperiodic oscillations. In the outburst of quasiperiodic oscillations of large amplitude, the instances of differential heats as high as 700 kJ/mol H2 have been detected, exceeding the heat of the gaseous water formation from elements (242 kJ/mol H2) by a factor of nearly 3. Another occurrence of anomalously high thermal effects has been measured in calorimetric oxygen titration using 0.09 μmol pulses of O2 injected onto hydrogen- or deuterium-saturated catalysts, including 2%Pd/Al2O3, 5%Pd/Al2O3 and 2%PdAu/Al2O3. Repeatedly, the saturation/oxidation cycles showed the heat evolutions in certain individual O2 pulses as high as 1100 kJ/mol O2, i.e., 550 kJ/ mol H2, again 2 times as much as the heat of water formation. It has been pointed out that it seems prudent for the PAR technologists to assume a much larger rate of heat evolution than those calculated on the basis of a standard thermodynamic value of the heat of water formation, in order to account for the possibility of large thermokinetic oscillation occasionally appearing in the recombination process of hydrogen. A possible relation of the anomalous heat evolution to an inadvertent occurrence of low energy nuclear reaction (LENR) phenomena is also briefly considered.

    ABSTRACT: The sorption equilibrium of methane (CH4) and nitrogen (N2) in binderless beads of 5A zeolite is presented between 305 and 373 K and pressures up to 3 bar in a static electronic microbalance. The adsorbed amount of CH4 and N2 is around 1.6 and 1.02 mol/kgads, respectively, at 305 K and 3 bar. A comparison of these values with the ones in literature shows that the adsorption capacity of the 5A binderless beads is 20% higher than that of the 5A binder commercial materials. The CH4 and N2 adsorption isotherms were fitted with the simplest Langmuir model with a prediction of the maximum amount adsorbed for both compounds of 5.0 mol/kg. The heats of sorption are −16.6 and −15.1 kJ/mol for CH4 and N2, respectively. In the overall pressure and temperature range the isotherms of N2 seems practically linear. However, it was observed that the experimental data of N2 at low coverage (below 0.2 bar) deviates slightly from Type I isotherms. Thereafter, the binary sorption of CH4 and N2 has been investigated in a fixed bed adsorber at 313 and 343 K and total pressures up to 5 bar for 50(CH4)/50(N2) and 75(CH4)//25(N2) mixture ratios diluted in an inert helium stream. A mathematical model was formulated to compute the dynamic behavior of the fixed bed adsorber using the extended binary Langmuir model, showing close agreement with the measured binary breakthrough experiments in the partial pressure range of the components above 0.2 and below 3 bar.

    ABSTRACT: A new type of hierarchical hemisphere-like CaCO3 (HSCC) was developed by a biomineralization method and incorporated into poly(p-dioxanone) (PPDO) by in situ ring opening polymerization (ROP) to develop the composites with comprehensive and good performances. The mechanical property, thermal stability, crystallization behavior, and degradation behavior of PPDO/HSCC composites were investigated. The tensile strength, the elongation at break, and the modulus of PPDO were enhanced simultaneously by the addition of HSCC, because of its good dispersion and interfacial adhesion with PPDO matrix. In addition, HSCC in composites also acted as a nucleating agent and enhanced the crystallinity of PPDO. The degradation rate of the PPDO/HSCC composites was enhanced with introducing 3 wt % HSCC, while 1 wt % HSCC did not change the degradation rate of PPDO. It was worth mentioning that, compared to PPDO, the pH value of incubation solution was more stable for PPDO/HSCC composites. Because HSCC could neutralized the acid residue, which illustrated the inflammation risk caused by the acid residue could be reduced. In particular, the good cell attachment and proliferation of both L929 and MG-63 cells was obtained for PPDO/HSCC with an HSCC amount of 3 wt %. The results indicated hierarchical HSCC played a very important role in improving the physical and biological properties of PPDO, which made PPDO/HSCC composites hold a promising application in bone tissue engineering material.

    ABSTRACT: Nonlinear model predictive control (NMPC) is an advanced control strategy that uses a rigorous dynamic model of the process, usually described by differential-algebraic equations (DAE), to predict its future behavior. The economic optimization of the process can be included directly in the objectives of the NMPC controller, which make it attractive for application in highly nonlinear and energy-intensive processes that are subject to fluctuating operational conditions. Currently, the implementation of NMPC controllers with large-scale dynamic models is limited by the computational difficulty of solving the associated dynamic optimization problem at each period of time. In this work, we propose an index two DAE model based on fundamental principles that uses its equivalent reduced index one model to define consistent initial conditions (index hybrid DAE) with the aim of representing the dynamics of a distillation column. We demonstrate that this model describes the same physical behavior of its equivalent index one reduced model and that it decreases significantly the computational complexity of the online optimization associated with the NMPC controller. Finally, we use the index hybrid DAE model in the economic oriented NMPC (EO-NMPC) of an extractive distillation column considering different disturbances over the inlet conditions. Also, we compare the EO-NMPC with a classic PI (proportional and integral) controller to show that the first one has a better dynamic performance and improves the economic profit of the process.

    ABSTRACT: In this work, the 2D and 3D population balance models of a MSMPR crystallizer has been developed in order to conduct linear stability analysis. Quantitative comparison of 1D, 2D and 3D models has been conducted to determine the range of applicability of these models in terms of prediction of stable behaviour of crystallizers. Both dynamic and steady state models have been solved for two crystals of practical importance: beta-L-glutamic acid (BLGA) and hydroquinone whose nucleation and growth models are well known. It has been shown that the 1D and 2D models agree in terms of stability if the exact shape factor is supplied to the 1D model. If the shape factor is taken to be unity, inaccurate results are produced by the 1D model. The shape factor must be known within 20% of its true value for reasonably accurate results from the 1D model with respect to stability. 3D model does not offer any additional advantage in this regard unless the growth rates in second and third dimension differ more than 30%.

    ABSTRACT: Spatially distributed first-principles process models provide an accurate physical description of chemical processes, but lead to large-scale models whose numerical solution can be challenging and computationally expensive. Therefore fast reduced order models are required for model-based real-time applications, such as advanced process control and dynamic real-time optimization. In this paper, we focus on the model reduction of a bubbling fluidized bed (BFB) adsorber, which is a key component of a post-combustion carbon capture system. From a temporal aspect, dynamic reduced models are generated using nullspace projection and eigenvalue analysis method, with the basic idea of quasi-steady state approximation for the states with fast dynamics. From a spatial aspect, dynamic reduced models are developed using orthogonal collocation and proper orthogonal decomposition to reduce the size of the rigorous model. Finally, a computationally efficient and accurate dynamic reduced order model is developed for the BFB adsorber by combining temporal and spatial model reduction techniques, which is suitable for an online optimization-based control strategy.

    ABSTRACT: Polylactide (PLA) was melt blended with either polypropylene (PP) or a polypropylene based elastomer (PBE, Vistamaxx) in an effort to improve its mechanical properties. An ethylene–glycidyl methacrylate–methyl acrylate terpolymer (PEGMMA, Lotader) was utilized as compatibilizer through coupling to the end groups of PLA. Graft copolymers formed enhanced the adhesion between PLA and polyolefin phases and lowered the interfacial tension. The morphological, mechanical, and rheological properties of the PLA/polyolefin compatibilized blends were investigated, and the blends exhibited substantial improvement in elongation at break and tensile toughness as compared to the corresponding binary blends. The remarkable efficacy of PEGMMA as a reactive compatibilizing agent allows the bridging of two immiscible but important classes of thermoplastics, polylactide and polypropylene, and the production of ductile PLA/PP blend materials.
