Building-integrated photovoltaics play a key role in the reduction of greenhouse gases emission towards sustainability in the building and construction sector. Organic solar technology holds several advantages such as lightweight, flexibility and semitransparency, suiting well for this type of application. When integrated into windows and facades, it provides a dual benefit: it acts as a solar radiation barrier, improving indoor thermal comfort, while also generating off-grid power. Besides that, organic devices are known to be more efficient than traditional photovoltaics based in silicon in diffuse and low light conditions. Nevertheless, only a few studies have been conducted in the area employing large-area commercial modules, in real operational conditions and for a long-term period. This work has the purpose of reducing this gap and shine a light on this debate bringing an analysis based on real data of a set of …

Microkinetic models allow the description of complex reaction kinetics but require high computational costs, hindering their combination with detailed reactor models. In this contribution, a methodology to develop a surrogate artificial neural network (ANN) was proposed and demonstrated for methanol synthesis on Cu/Zn-based catalysts. The resulting model accurately reproduces the simulations of the original microkinetic model, reducing the computational costs by orders of magnitude. In the developed methodology, the ANN learns only the kinetics of the global reaction rates, thereby decreasing model complexity and computational costs while ensuring thermodynamic consistency. In addition, an improved activation function for the ANN was designed in this work to minimize computational costs and to smooth out calculations. The proposed approach creates a bridge to integrate microkinetics into applications in …

This study presents an exergetic analysis of xylitol fermentative production from hemicellulose hydrolysate, aiming to optimize operational conditions in a fluidized bed bioreactor. The aerobic fermentation conditions evaluated in this study (gas flow rate-x 1, hydrolysate concentration factor-x 2, and recirculation flow rate-x 3) were optimized using various exergetic parameters and xylitol yield as objective functions. Four objective functions were defined for the mono-objective optimization process: rational exergetic efficiency, normalized destroyed exergy, thermodynamic sustainability index, and xylitol yield factor. The results reveal that the optimization problem involves conflicting objectives when considering both yield-based and exergy-based approaches. Thus, the bioreactor's performance was formulated as a multi-objective problem, where the yield factor and thermodynamic sustainability index were …

Quicklime, a globally significant commodity used in various industrial applications, is produced in limekilns requiring substantial energy, traditionally, from fossil fuels. However, due to escalating emission constraints and depletion of fossil fuel deposits, the quicklime industry explores alternative fuels, like biomass. The literature lacks feasibility diagnostic studies on limekilns using alternative biomass fuels. Thus, this article aims to conduct energy and exergy diagnostics on an industrial limekiln using producer gas derived from eucalyptus wood as renewable biofuel. Employing industrial data and thermodynamics principles, the equipment was characterized, and results were compared with literature findings for similar limekilns using fossil fuels. The Specific Energy Consumption for the producer gas-operated limekiln was 4.8 GJ/t quicklime, with energy and exergy efficiencies of 54.6% and 42.2%. Overall energy and exergy efficiencies were 42.0% and 23.6%, respectively, lower than literature values. was 7.6 GJ/t quicklime, higher than literature results. Identified enhancements for both renewable and fossil fuel-powered limekilns involve recovering energy and exergy, including heat recovery from exhaust gases, minimizing thermal losses, and optimizing operational variables. These findings offer valuable insights for researchers exploring renewable biofuel adoption, like producer gas derived from eucalyptus wood, as alternatives to conventional fossil fuels in limekilns.

Given the increasing use of electricity and the current environmental challenges, ensuring efficiency and sustainability in power generation must be a major concern for society. In this context, energy and exergy analysis are useful to assess the efficiency and sustainability of different economic sectors. Hence, an exergy-based sustainability analysis of the Brazilian power generation sector was performed based on operational data from 2000 to 2020. The overall exergy efficiency of this sector varied from 63.3% to 75.0%. Thermal power generation was identified with the largest improvement potential. Several sustainability indicators were used to address the sector’s sustainability. It was found that the depletion number varied between 0.25 and 0.37, while the sustainability index ranged from 2.73 to 4.00. The behavior of the indicators, such as relative irreversibility, lack of productivity, waste exergy ratio, and …

In this study, industrial styrene reactors were optimized using the multi-objective algorithm Generalized Differential Evolution 3 (GDE3) to maximize their conversion and selectivity. When modeling the reactors, an intrinsic heterogeneous reaction model was adopted to produce realistic results, which would adequately encompass the complex influence of the decision variables in the system. Several optimal scenarios were obtained using two- and three-objective approaches, which can be used in integrated process analysis to define suitable operational conditions. These scenarios were studied from a fundamental perspective to explore the impact of the steam-to-ethylbenzene molar feed ratio, the number of catalyst beds, catalyst loading, operating pressure, and inlet temperatures on reactor performance. Furthermore, our GDE3 implementation has been made available in a public code repository and a Python …

Osmotic dehydration (OD) is a technique used for the partial removal of water from foodstuff, including fruit and vegetables, with the aim of producing a desiccated product. The process involves placing the material in a hypertonic solution for several hours and allowing water to move from the cell compartment into the solution by osmosis. OD is influenced by various factors such as the concentration and composition of the osmotic solution, the solution temperature, the type of agitation and the time of exposure, as well as the size, shape and compactness of the food material. The main advantages of OD over conventional drying processes are the superior quality of the dried products and the minimization of shrinkage. In recent years, research effort has focused on the combination of OD with other technologies, such as ultrasound, cryogenic freezing with liquid nitrogen, pulsed electric field, gamma radiation and high hydrostatic pressure. The application of these methods prior to or concomitant with OD accelerates mass transfer and reduces the drying rate of fruit and vegetables by increasing the permeability of cell membranes. In this manner, combined processes tend to be more efficient and economical in comparison with conventional OD because they reduce operating times and; consequently, energy consumption. In addition, the dried products generated by such coupled processes typically exhibit improved nutritional and physicochemical characteristics. This review summarizes the basic principles and applications of OD in combination with other methods, with particular emphasis on the production of dried fruits

Among the steps for the conversion of biomass into bioenergy, there is enzymatic hydrolysis. However, factors such as composition, formation of inhibitors, inhibition and enzymatic deactivation can affect the yield and productivity of this process. Lignocellulosic biomass is composed of cellulose, hemicellulose and lignin. However, lignin is organized in a complex and non-uniform way, promotes biomass recalcitrance, which repress the enzymatic attack on cellulose to be converted into glucose, and, consequently, the production of biofuel. Thus, a challenge in enzymatic hydrolysis is to model the reaction behavior. In this context, this study aims to evaluate the performance in enzymatic hydrolysis for the conversion of cellulose present in sugarcane bagasse into glucose. Therefore, modeling and optimization will be proposed to produce high glucose concentration rates. Therefore, a previously developed study will be used, in which the authors proposed a kinetic model for the hydrolysis step. However, as a differential to what has been proposed, the calculation will be carried out evaluating the evaporation, in order to maximize the response to the glucose concentration. Thus, considering evaporation and optimized kinetic parameters, it was possible to obtain high rates of glucose concentration at 204.23 $g.L^{-1

The literature reveals the application of the laws of thermodynamics for predicting life span and the effects of the physical activity level on longevity. But the vastly simplified literature models seem to suggest a reduction in duration of life with increased activity level, which is the opposite of medical recommendations, that means that exercises increase the longevity. The main objectives of this paper are to re-present the previous model, check and confirm the previous results and improve the model by formulating a simplified phenomenological relation between life span, specific entropy generation of the body (SEG-life, in MJ/kg.K) and physical activity level. The model was validated considering different individuals. In this study, it is suggested that the principle of cumulative entropy generation limit should be relaxed in function of lifestyle and type of exercise performed during life, differently from what it is defined by the literature. So, it is proposed a relax to the limit on SEG-life as a result of various physical activity levels.

O presente trabalho visa analisar a influência de parâmetros operacionais no transporte simultâneo de calor e massa durante o processo de secagem da madeira, por meio de simulação computacional. Nesse intuito, utilizou-se um modelo matemático que aborda o fenômeno como sendo intrinsecamente difusivo, sendo constituído de um sistema de equações diferenciais parciais acopladas. Sua resolução foi numericamente alcançada por meio da aplicação do método das linhas. As simulações consideraram uma placa de madeira de Pinus elliottii submetida às condições típicas de secagem em uma estufa convectiva convencional. A validação dos resultados teóricos foi realizada a partir da comparação com dados experimentais da literatura. As simulações mostram a formação de um gradiente de umidade expressivo no início do processo. Também foi observada a ocorrência da redução gradual da taxa de secagem e a significativa influência da espessura da peça na velocidade de secagem. As interferências associadas à termodifusão e ao efeito Soret mostraram-se pouco apreciáveis. A concordância das observações inferidas dos resultados teóricos com os dados experimentais sustenta que o modelo possui relativa eficiência na predição do comportamento do material quando submetido a condições operacionais específicas.

Um tanque cilíndrico de armazenamento energético, presente em um sistema de aquecimento, é estudado neste trabalho. O emprego de um material que sofre mudança de fase em um tanque de armazenamento energético permite o uso de tanques menores, já que o calor latente de fusão é muito superior ao calor sensível, para as variações de temperatura obtidas com coletores solares. A fim de prever o comportamento diurno do tanque, período no qual a energia é continuamente armazenada, emprega-se um modelo da literatura baseado no método entalpia. Com modificações na estratégia de resolução numérica da literatura, propõe-se uma correção na equação empregada para a entalpia de modo a torná-la contínua e também a integração direta do sistema de equações algébrico-diferenciais, resultante da discretização do modelo nas 2 direções espaciais em volumes finitos, num integrador comercial do MATLAB. A rotina de integração empregada permite o controle dos erros, o que é mais difícil de ser realizado empregando-se o método de Euler Implícito usado no trabalho da literatura. Mais além, nesta nova metodologia, não se faz mais necessário o uso de propriedades constantes (calores específicos e condutividades térmicas). O sistema simulado emprega CCHH (Cloreto de Cálcio Hexahidratado) no tanque de armazenamento e água como fluido de transferência de calor. O tempo simulado de fusão completa foi empregado para a análise de convergência da malha e considerou-se convergida a solução com 17 divisões tanto na direção radial quanto axial.

A modelagem e simulação é uma ferramenta utilizada em industriais para avaliar o comportamento de um processo em diferentes condições operacionais. Na literatura, existem pesquisas diversas relacionadas à modelagem matemática e simulação de reatores. Porém, tem-se a dificuldade numérica na solução de problemas com termo convectivo dominante. Assim, o presente trabalho desenvolve a solução analítica a partir de uma equação diferencial parcial para o problema de um reator em regime transiente, considerando difusão e convecção dominante. Essa solução analítica depende do adimensional número de Péclet mássico e módulo de Thiele. Como o número de Péclet fornece uma razão entre os fluxos convectivo e difusivo, a solução analítica empregada usou elevados valores de Péclet para simular condições de escoamento com efeito convectivo mais significante que o difusivo, e consequentemente empregou-se também elevados valores para o módulo de Thiele. São simulados os perfis com o número de Péclet variando de 2 a 50, sendo que no valor mais elevado fica evidenciada a dominância da convecção pelo perfil praticamente linear de concentração de reagente ao longo do reator em regime permanente. Os resultados obtidos são fisicamente coerentes e a solução analítica pode ser usada na análise de convergência e estabilidade de soluções numéricas.

The proposed work consists of the analysis of the temperature influence on thermophysical properties in the three-dimensional computational numerical simulation of heat transfer in human biological tissue in the presence of a tumor. The tissue consists of layers of muscle, fat, and skin. The tumor was considered in the muscle layer. The Pennes model was used to describe the heat diffusion in the tissues. Two approaches were analyzed, one with constant thermophysical properties and the other with temperature dependent properties. In addition, two distinct cases were analyzed, one in which the tumor is already developed and another where it is still in the development stage. The temperature profile showed small differences between the approaches; however, the difference of the temperature gradient is noteworthy. The model with constant properties tends to overestimate the temperatures and to underestimate …

In this study, steady-state axial-flow and radial-flow multibed catalyst reactors for dehydrogenation of ethylbenzene into styrene were simulated based on an intrinsic heterogeneous kinetic model. The reactors were then optimized using nonlinear programming with the multiobjective function of maximizing styrene selectivity and conversion. The simulations were consistent and versatile. Comparing the two optimized reactor configurations, radial-flow has proved to be a better alternative than axial-flow because of operating at lower pressures. The benefits of operating at lower pressures are also evident at optimized inlet temperature schemes, as the inlet temperatures of catalyst beds are greater along reactor pressure drop. The obtained set of optimal results can be used to perform an integrated process analysis and define suitable operational conditions. Weighing objective functions with respectively 0.3 and 0.7 …

The most energy demanding process in the cement industry is clinker production, carried out in a rotary kiln. Thus, rotary kiln energetic and exergetic analyses are useful tools to reach cement production process improvements. Energetic analysis is based on the first law of thermodynamics and allows one to calculate the heat uses and losses. On the other hand, exergetic analysis is based on a combination of the First and Second Laws of Thermodynamics and allows quantifying process irreversibilities. Some rotary kiln exergy analyses neglect the mass flows chemical exergy in the exergetic analysis, considering only the fuel chemical exergy. In this work, chemical exergy impact on this analysis was evaluated. Pre-calcination effect was also studied. Rotary kiln classical and modern exergetic efficiency considering all the chemical exergy contributions were 55.5% and 41.8%, respectively, while considering …

Proper simulation of processes of the natural gas industry such as dehydration, liquefaction and regasification require accurate prediction of thermodynamic properties of the working fluids. For such processes, cubic equations of state are the calculation methods most frequently employed. Among them, the Peng-Robinson equation is usually the one recommended for gas, refinery and petrochemical applications in many simulators. Numerous works have been proposed in order to improve the temperature dependence relation of the attraction parameter of the equation – the so called alpha function. In this work, five currently available alpha functions are evaluated for the prediction of molar volumes and enthalpies of natural gas samples. Additionally, parameters of one of the models are readjusted to volumetric data of methane, in order to represent its supercritical behavior more accurately. Experimental data of 44 mixtures are compared with calculated results. Van der Waals mixing rules are used, with binary interaction parameters set as zero. In the case of the original alpha function, it is also tested how the inclusion of non-zero binary parameters affects the predictions. The extended Saffari-Zahedi model presents the smallest average deviation for the molar volumes (1.35%). For the enthalpy calculation, the inclusion of the binary parameters results in deviation values of 2.62% for gas-gas transitions and 4.44% for gas-liquid transitions.

The present study aimed to evaluate the temperature profile along the inside of the wall of a clinker kiln from a cement industry. The problem was modeled by the equation of transient heat conduction in cylindrical coordinates, considering radial symmetry. Being the wall composed of different materials, even adopting constant physical properties, there is no analytical solution to the problem. The method of the lines was used, being the radial and axial directions discretized by finite differences and the resulting system of ordinary differential equations integrated in time until obtaining the temperature field in steady state. The obtained field was compatible with heat transfer fundamentals and presented a good fit in relation to industrial data. The main limitations of the modeling performed in this study include the fact that the gases and solids contained in the kiln have not been modeled, and the variation in thicknesses of the layers of the kiln wall has not been considered. The program developed in this study can be used to evaluate the performance of different refractories or to infer the refractory wear level from experimental kiln surface temperature profiles.
