Zeolitic imidazolate framework (ZIF) membranes are emerging as a promising energy-efficient separation technology. However, their reliable and scalable manufacturing remains challenge. We demonstrate the fabrication of ZIF nanocomposite by means an all-vapor-phase processing method based on atomic layer deposition (ALD) ZnO in porous support followed ligand-vapor treatment. After ALD, obtained exhibits low flux is not selective, whereas after (2-methylimidazole) treatment, it partially...
This paper deals with system integration and controller design for power management of a stand-alone renewable energy (RE) hybrid system, which is at the construction stage in Lambton College (Sarnia, ON, Canada). The consists five main components: photovoltaic arrays, wind turbine, electrolyzer, hydrogen storage tanks, fuel cell. model each process component developed, all components are integrated Matlab/Simulink environment. A two-level control implemented, comprising supervisory...
This paper focuses on the design and optimization of a process for production 5-hydroxymethylfurfural (HMF), sugar derived molecule that can be used as raw material in furan based polymers. We start by reviewing processes kinetic mechanisms involved its synthesis from fructose then consider continuous using solvent extraction semi batch concept proposed Roman-Leshkov et al. formulate an problem order to find operating conditions minimize cost per mol HMF produced study effect different...
Abstract Process control and optimization have been widely used to solve decision-making problems in chemical engineering applications. However, identifying tuning the best solution algorithm is challenging time-consuming. Machine learning tools can be automate these steps by behavior of a numerical solver from data. In this paper, we discuss recent advances (i) representation for machine tasks, (ii) selection, (iii) configuration monolithic decomposition-based algorithms. Finally, open...
Abstract This article deals with distributed parameter systems described by first‐order hyperbolic partial differential equations (PDEs), for which the manipulated input, controlled output, and measured output are in space. For these systems, a general output‐feedback control methodology is developed employing combination of theory PDEs concepts from geometric control. A concept characteristic index introduced used synthesis state‐feedback laws that guarantee tracking closed‐loop system....
Abstract The output feedback control problem is addressed for a class of nonlinear multivariable high‐index differential‐algebraic‐equation systems in semiexplicit form. Initially, an algorithmic procedure developed and used to derive equivalent state‐space relization the constrained system. An synthesis then formulated on basis derived realization solved through combination state appropriate observers. methodology applied two‐phase reactor, its performance robustness characteristics are...
Abstract This paper concerns general MIMO nonlinear processes, whose dynamic behavior is described by a standard state‐space model of arbitrary order, including measurable disturbances. The concept relative order an output with respect to input, extended include disturbance as well manipulated inputs, generalized in context and it used obtain characterization the interactions among input variables. A synthesis formula calculated for feedforward/state feedback control law that completely...
This paper proposes a mixed integer linear program for determining economical biomass processing facility locations and capacities, applies it to assess the biofuel supply chain of Midwestern United States feasibility meeting governmental mandates in 2015. Existing corn ethanol facilities new candidate sites are considered production by utilizing eight types biomass. The spatial distribution farmgate cost is accessed from recently updated U.S. Department Energy database. Seven technologies...
Biorefineries are facilities for the production of fuels and chemicals from biomass, which can tackle increasing emissions carbon dioxide. In this paper, we formulate a systematic biorefinery process synthesis problem with goal finding these products technologies result in highest economic potential or efficiency. Our approach allows explicit evaluation comparison different configurations. We also aim to investigate relationship (and competition) between production. initially develop...
Synthetic ammonia produced from fossil fuels is essential for agriculture. However, the emissions-intensive nature of Haber–Bosch process, as well a depleting supply these have motivated production using renewable sources energy. Small-scale, distributed processes may better enable use renewables, but also result in loss economies scale, so high capital cost process inhibit this paradigm shift. A that operates at lower pressure and uses absorption rather than condensation to remove unreacted...
