“…The world production of fossil fuels nearly increased monotonically in the range of 9.76-11.39 ×10 3 Mtoe with an increase rate of 16.70%. These were 85.68%-87.81% (Rosen, 2009b;Romero and Linares, 2014;Bilgen and Sarıkaya, 2015;Rosen, 2017a) Figure 2. Four key factors involved in sustainable development (Dincer and Rosen, 2005) of world primary energy consumption (11.27-13.15 ×10 3 Mtoe), indicating that the fossil fuels contributed significantly to the world primary energy consumption.…”

“…Generally, sustainability encompasses several perspectives or pillars. Most of the scholars prefer that sustainability is a triangle of economic sustainability, environmental sustainability, and social sustainability which is shown in Figure 1 (Rosen, 2009b;Romero and Linares, 2014;Bilgen and Sarıkaya, 2015;Rosen, 2017 a). Dincer and Rosen (2005) furthered to state that sustainable development involves four key factors: environmental sustainability, economic sustainability, social sustainability, and resource/energy sustainability (Figure 2).…”

“…When we talk about sustainable development, sustainable energy/fuel resources should be available, and they should be efficiently used (Rosen, 2002;Dincer and Rosen, 2005;Kanoglu et al, 2009;Bilgen and Sarıkaya, 2015). …”

“…To reduce the gaseous pollutants (SOx, NOx, CO, CH4, etc.) from a fuel convention or utilization process, one efficient alternative is to improve the process efficiency which is best evaluated by exergy efficiency (Rosen and Dincer, 2001;Kanoglu et al, 2009;Caliskan, 2014;Bilgen and Sarıkaya, 2015). For a general fuel convention or utilization process, the best way to reduce the environmental impact and increase the fuel sustainability is to improve the exergy efficiency of the process (Figure 12) (Rosen and Dincer, 2001;Rosen et al, 2008;Kanoglu et al, 2009).…”

At the same time of providing a huge amount of energy to the world population (social sustainability) and global economy (economic sustainability), the fuel itself also releases a great amount of emissions to the environment the world people live in in the forms of gaseous pollutants (SOx, NOx, CO, CO2, CH4, etc.) and ash compositions (Al2O3, CaO, Fe2O3, K2O, MgO, MnO, Na2O, P2O5, SO3, SiO2, TiO2, etc.), seriously impacting the environment (environmental sustainability) for the world population and global economy. Sustainability generally encompasses economic sustainability, environmental sustainability, and social sustainability, and all of these are significantly related to the energy/resource sustainability. This study addresses the sustainability of fuel from the viewpoint of exergy. It is demonstrated that the energy of a fuel is best evaluated by its chemical exergy, and the environmental impact of a fuel can be assessed through the chemical exergy of its emissions (the specific impacts such as toxicity or greenhouse effect are not detailed). Then, the sustainability of fuel can be understood from the viewpoint of exergy through three ways: (a) high chemical exergy of the fuel, (b) high exergy efficiency of the fuel conversion process, and (c) low chemical exergy of the emissions.

Shell and Tube Heat exchangers (STHEs) are the most common type of heat exchangers. They are applied in numerous industrial installations. The minimization of the costs of these heat exchangers is a key goal for both designers and users. The design of this type of heat exchanger involves complex processes, including selection of the geometrical and operating parameters. The traditional design approach of Shell and Tube Heat Exchangers consists of the evaluation of a number of different exchanger geometries to identify those satisfying a requirement of heat and a set of geometric and operational constraints. However, this approach is slow, inaccurate and does not guarantee an optimal solution. In this paper, different evolutionary algorithms to optimize STHEs economically are analyzed and applied, including the particle swarm optimization, genetic algorithms and mixed ant colony optimization, this last one developed by the authors. As objective function the minimization of total annual cost was considered. For optimization were considered as independent design variables the inside diameter of the shell, the outer pipe diameter and spacing between the baffles. They were also considered for optimizing two patterns or arrangements of tubes, in a triangle and a square. An example of three case studies of optimization of heat exchanger is presented. The results of the optimization using the mixed ant colony technique are compared with those obtained using particle swarm and genetic algorithms.Key words: Heat exchangers, optimization, evolutive algorithms, ant colony.Minimización del costo de los intercambiadores de calor de tubo y coraza mediante algoritmos evolutivos RESUMEN Los intercambiadores de calor de tubo y coraza (ICTC) son el tipo más común de los intercambiadores de calor. Los mismos se aplican en numerosas instalaciones industriales. La minimización de los costes de estos intercambiadores de calor es un objetivo clave tanto para los diseñadores como para los usuarios. El diseño del intercambiador de calor implica procesos complejos, incluyendo la selección de los parámetros geométricos y parámetros de funcionamiento. El enfoque tradicional de diseño para los intercambiadores de calor de tubo y coraza consiste en la evaluación de un determinado número de geometrías diferentes del intercambiador para identificar aquellas que satisfacen un requerimiento de calor y un conjunto de restricciones geométricas y operacionales. Sin embargo, este enfoque es lento, poco preciso y no garantiza una solución óptima. En el presente trabajo se analizan y aplican diferentes algoritmos evolutivos para optimizar económicamente los mismos, entre ellos la optimización con enjambre de partículas, por algoritmos genéticos y por colonia de hormigas mixto, este último desarrollado por los autores. Como función objetivo se consideró la minimización del costo total anual. Para la optimización se consideraron como variables independientes de diseño el diámetro interior de la coraza, el diámetro exterior del tubo y el espaciami...
