    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: 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.

    ABSTRACT: In this special dedication paper in the D. Ramkrishna Festschrift, several remarkably simple results in viscous fluid mechanics (also known as microhydrodynamics) are examined in the context of linear operator theory and the properties of self-adjoint operators. In particular we highlight for the broader chemical engineering community that for a small sphere undergoing rigid body motion (RBM) in Stokes flow, the surface tractions are simply a multiplicative constant times that same RBM, and that this amazing and simple result is the consequence of linear operator theory applied to the relevant self-adjoint operator. So as to provide an illustrative example of the general theory that this can be true only for the sphere, we reexamine the corresponding classical (1876 and 1964) results for the surface tractions on an ellipsoid. The ellipsoid not only provides the example as expected, but produces a useful result that in the so called mobility problem where the force on the ellipsoid is the known input, the surface tractions can be cast in a very simple form that is independent of elliptic integrals and other complexities usually associated with ellipsoidal geometries. This connection between linear operators and transport phenomena highlights the power of mathematics in unifying the pedagogical framework for chemical engineers and the great influence of Professor Ramkrishna over the past half-century.

    ABSTRACT: This work presents experimental implementation of an improved single-column chromatographic (ISCC) separation process and its optimizing controller. A mixture of guaifenesin enantiomers has been used to evaluate the performance and integrity of: (i) the ISCC process and its online monitoring system in open-loop experiments, and (ii) the model predictive optimizing controller for closed-loop operation. The open-loop operation has been particularly aimed at assessing the accuracy and precision of the online monitoring system. In the closed-loop operation, the performance of the developed model predictive control (MPC) scheme has been tested for set-point tracking and disturbance rejection with an objective function that reflects the process economics. The online optimal operating condition was also compared to offline optimum condition obtained using genetic algorithm. Results confirm that the optimizing controller is adequate to operate and maintain the ISCC process at optimal operating point while fulfilling the product requirements.

    ABSTRACT: In this study, a series of biobased and biodegradable thermoplastic poly(ester urethane)s (PEUs) with different compositions were synthesized via chain extension reaction of dihydroxyl terminated poly(propylene succinate) (HO-PPS-OH) and poly(butylene succinate) (HO-PBS-OH) with 4,4'-methylenediphenyl diisocyanate (MDI) as a chain extender. The thermal behaviors of PEUs were characterized by differential scanning calorimeter (DSC) and thermogravimetric analysis (TGA). All the PEUs showed a single glass transition temperature shifting with compositions, only one melting peak was observed when the feeding weight ratio of PPS to PBS was less than 8:2, and the crystallization ability of the PEUs decreased gradually with the increase in PPS content. The tensile and tensile hysteresis tests suggest that the PEUs showed the tensile behaviors of elastomers when the weight ratio of PPS/PBS were 7/3, 6/4 and 5/5 and the tensile hysteresis value and Young’s modulus increased with increase in PBS content. The tensile strength and elongation at break of the three PEU elasomers exceeded 37 MPa and 1600%. Enzymatic (Candida rugosa lipase) hydrolysis study showed that the degradation rate increased with PPS fraction, according to the weight loss measurement and scanning electron microscopy observation.

    ABSTRACT: This research focused on the design and optimization of a two-phase Fischer-Tropsch (F-T) reactor in a gas-to-liquid (GTL) process. For the design of the F-T reactor, the overall process configuration was developed using the Aspen HYSYS® software. Various reaction mechanisms for the F-T process over iron-based catalysts were reviewed from the published literature. The F-T kinetics was adopted for reactor modeling, and the reaction kinetic parameters were adjusted to increase the accuracy of the modeling results. Furthermore, the effects of catalyst size, catalyst active sites, and reactor configuration were considered in the modeling. The yields of the F-T process were analyzed under various operating conditions. Finally, operating conditions, such as the temperature and pressure of the two-phase reactor model, were optimized to maximize the total amount of hydrocarbon products.

    ABSTRACT: Grain boundary defects are normally formed in zeolite membranes during membrane preparation and calcination processes. In this work, a siloxane polymer coating with the imidazole group was grafted on the surface of defective SSZ-13 membranes by chemical liquid deposition to seal the defects. The parameters such as silanization time, polymerization time, monomer type and concentration were optimized. Characterizations including Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM) and energy dispersive x-ray spectroscopy (EDX), showed that siloxane polymers were coated on the surfaces of SSZ-13 crystals and membrane. Six modified membranes showed decreased CO2 permeance by only 21±5% [average CO2 permeance of 1.9×10-7 mol/(m2 s Pa)] and increased CO2/CH4 selectivity by a factor of 9±3 (average CO2/CH4 selectivity of 108) for an equimolar CO2/CH4 mixture at 298 K. CO2/CH4 and CO2/N2 selectivities of the modified membrane decreased with pressure and temperature. Membrane stability was investigated for a long-time test and exposures to water vapor at temperatures up to 378 K and to some organic solutions. This modification method is also effective in sealing the defects of other zeolite membranes such as AlPO-18 membranes.

    ABSTRACT: The potential for successful automatic control of blood glucose concentration (BGC) has entered a new era due to recent technological advancements in insulin pumps and blood glucose sensors. However, a critical advancement necessary for full automation and long-term use is a control algorithm that can effectively maintain tight control of BGC under extreme variation of important disturbances such as activity, stress, and food consumptions. Since feedforward control (FFC) models disturbances directly it has the potential to eliminate the effects of disturbances completely. A Wiener-type feedforward control law is limited to the inclusion of only input (i.e., modeled disturbances and the manipulated variable) dynamics. Using a semi-coupled modeling network that includes pseudo blood insulin concentration, this work presents a more phenomenological FFC law that includes input dynamics, blood insulin and blood glucose dynamics and blood glucose levels. Modeling results on fifteen adults with type 1 diabetes mellitus for the proposed method are nearly identical to Wiener modeling results.

    ABSTRACT: The interfacial properties and interactions between phosphatidylcholine (PC) vesicles and surfaces (air/water, oil/water or oil/ethanol) were investigated as regards stability of the dispersed systems. Understanding interactions between the PC vesicles and different solutions is very important to make it easier to recognize various physiological functions of membranes. The interactions and possibility of creating stable PC-based systems were studied by different techniques, such as surface tension, microelectrophoresis, static and dynamic light scattering measurements. Besides the physicochemical characteristics another aim of the paper was the development of PC-based (micro)emulsions and the changes in their microstructure. Dispersion stability by droplet size and zeta potential determination was correlated with the changes of interfacial tension. Pseudoternary phase diagrams have been constructed to evaluate the phase behaviour of the systems containing n-tetradecane/ phosphatidylcholine, water (or ethanol) at different weight ratios. The presence of ethanol changes the area per lipid molecule and the layer thickness, therefore the capability of phospholipid adsorption at the oil/alcohol interface was dependent on the ethanol concentration and increases with its increase. Using of aqueous-ethanolic phase make it possible to obtain a small region of o/w and w/o PC-based microemulsions. This study has shown that nature of biosurfactant, ethanol concentration and proportion of the oil to water phase are the most important for processing and stability of the phosphatidylcholine-based emulsions. The obtained results expand the characteristics of the oil/phospholipid systems having large application potential.

    ABSTRACT: Successful implementation of solar thermochemical metal oxide water splitting cycles is dependent upon the ability to reach low partial pressures of oxygen during the thermal reduction step. Low partial pressures of oxygen are required to provide a thermodynamic driving potential for the thermal reduction reaction and avoidance of recombination. Achieving low partial pressures of oxygen (e.g. < 10-2 bar) may require a non-trivial energy input to the solar-to-fuel conversion process, negatively impacting the solar to fuel energy conversion efficiency. Three different strategies to reduce the partial pressure associated with oxygen generated during an iron oxide thermal reduction process were investigated using an open system thermodynamic analysis. These strategies include vacuum pumping, purging with an inert gas, and purging with steam. Open-system thermodynamic simulations show that vacuum pumping will yield approximately twice the overall cycle energetic and exergetic efficiencies of inert purging; assuming oxygen separation is required every cycle in the case of inert or steam purging. To demonstrate the concept of vacuum pumping, thermal reduction of an iron-zirconia bed in a tubular reactor was performed at low pressures of approximately 10-4 bar at a temperature of 1450°C. The maximum extent of reduction (14.2 ± 1.7 mol %) was reached after approximately 1 hr of reduction at 1450°C, while the predicted theoretical extent of reduction ranges from 16.5 mol % at 10-2 bar to 76.9 mol % at 10-4 bar. In the present analysis, reaction kinetics are not considered and its application is limited to the thermodynamically driven processes.

    ABSTRACT: Quaternary ammonium was successfully prepared on coconut shell activated carbon (CSAC) granules. The samples were characterized by FT-IR, N2 adsorption-desorption, XPS, TG and EA. The immobilized quaternary ammonium was thermally stable below 320 °C. The amount of immobilized quaternary ammonium on the CSAC was 0.957 mmol/g. Continuous cycloaddition of CO2 to epichlorohydrin (ECH) was carried out in a packed-bed reactor without using solvent or cocatalyst. When the reaction conditions were 130 °C and 1.4 MPa, the conversion of ECH and the corresponding turnover frequency (TOF) were 43.5% and 64.6 h-1, respectively. The selectivity to epichlorohydrin carbonate (ECHC) reached ~100%. In biogas upgrading, grafting of quaternary ammonium was demonstrated to enhance CO2 capture capacity of the CSAC. The saturated CO2 capture capacities of the CSAC and the quaternary ammonium functionalized CSAC were 1.82 and 2.40 mmol/g at 20 °C and 0.5 MPa, respectively. The adsorption selectivities of CO2 over CH4 were ~ 67 % and 85 % for the CSAC and the supported quaternary ammonium, respectively. The adsorption heat was 20~30 KJ/mol for the adsorbents. The supported quaternary ammonium also exhibited a relatively stable cyclability in a packed bed.

    ABSTRACT: Treatment of type 1 diabetes mellitus could be greatly improved by applying a closed-loop control strategy to insulin delivery, also known as an artificial pancreas (AP). In this work, we outline the design of a fully implantable AP using intraperitoneal (IP) insulin delivery and glucose sensing. The design process utilizes the rapid glucose sensing and insulin action offered by the IP space to tune a PID controller with insulin feedback to provide safe and effective insulin delivery. The controller was tuned to meet robust performance and stability specifications. An anti-reset windup strategy was introduced to prevent dangerous undershoot toward hypoglycemia after a large meal disturbance. The final controller design achieved 78% of time within the tight glycemic range of 80-140 mg/dL, with no time spent in hypoglycemia. The next step is to test this controller design in an animal model to evaluate the in vivo performance.

    ABSTRACT: Novel particle electrodes- red mud particle electrodes(RMPEs)were prepared using waste material-red mud, zeolite slag and iron powder with a mass ratio of 5:3:2 and used in a biological aerated filter coupled with three dimensional particle electrode reactor (BAF-TDE) for municipal wastewater treatment.The physical, chemical characters of RMPEs were measured. The surface morphology of the RMPEs was also characterized by SEM. The results showed that: (1) in the optimal sintering conditions, red mud could be used to manufacture RMPEs; (2) BAF-TDE had an advantage over the single BAF on the removing organic matter and ammonia nitrogen; (3) In the system of BAF-TDE, BAF contributed more to the removing organic matter and ammonia nitrogen than TDE did, while TDE played a crucial important role in BAF-TDE improved by introducing electric field.

    ABSTRACT: We present a reduced order multi-mode transient model for describing temperature variations in a catalytic monolith consisting of a flow channel, a thin washcoat layer in which one or more chemical reactions occur, and a ceramic or metallic support. The model developed is accurate to first order in the transverse conduction time and is valid over a wider range of operating conditions and kinetics compared to the widely used traditional two-phase model. We provide a physical interpretation of the various effective transport coefficients appearing in the reduced order model and show that it reduces to the commonly used two-phase model only in the limit of very slowly varying inlet conditions or very slow reactions. In the general transient reacting case, we show that the traditional heat transfer coefficient concept is not applicable as the solid-fluid interfacial heat flux cannot be expressed in terms of the difference between any two phase averaged temperatures even to leading order. We use the reduced order model to examine the light-off behavior of the monolith and the speed and width of the temperature fronts as a function of various monolith parameters.
