Ítem A Comparative Assessment of Emerging Solvents and Adsorbents for Mitigating CO2 Emissions From the Industrial Sector by Using Molecular Modeling Tools(Frontiers Media S.A., 2020-01-01) Bahamon D.; Alkhatib I.I.I.; Alkhatib N.; Builes S.; Sinnokrot M.; Vega L.F.; Universidad EAFIT. Departamento de Ingeniería de Procesos; Desarrollo y Diseño de ProcesosThe possibilities offered by molecular modeling tools to obtain relevant data at process conditions, while also gaining molecular insights on the techniques used for CO2 capture and separation, are presented here using selected case studies. Two different technologies, absorption with amine-based systems and adsorption on porous materials, were explored, using the molecular-based equation of state, soft-Statistical Associating Fluid Theory (SAFT), and Grand Canonical Monte Carlo simulations, respectively. The aqueous monoethanolamine (MEA) system was set as the benchmark for absorption and compared to the performance of 8 alternative amine-based systems, while 16 adsorbents belonging to different families (zeolites, metal–organic frameworks, amorphous silicas, and activated carbons), bare or functionalized with alkylamines, were investigated for the separation of CO2 by adsorption. In addition to obtaining molecular information on the CO2 capture process, the models were further used to examine the CO2 capture performance in terms of cyclic working capacity and energy index as key performance indicators, allowing the identification of promising systems that can improve the current ones to be further evaluated for separation in non-power industries. Results show that for the same total amine mass concentration, non-aqueous amine solvents have a 5–10% reduction in cyclic working capacity, and a 10–30% decrease in the energy index compared to their aqueous counterparts due to their lower heat of vaporization and specific heat capacity. In addition, M-MOF-74, NaX, and NaY structures present the best results for adsorption in temperature swing adsorption (TSA) processes. Similar values of energy requirements to those of amine-based systems (2–2.5 MJ kg CO2–1) were obtained for some of the adsorbent; however, the disadvantage of the TSA process versus absorption should be considered. These results confirm the reliability of molecular modeling as an attractive and valuable screening tool for CO2 capture and separation processes. © Copyright © 2020 Bahamon, Alkhatib, Alkhatib, Builes, Sinnokrot and Vega.Ítem Diseño del departamento de mercadeo y apoyo comercial de la empresa Hierros HB S. A.(Universidad EAFIT, 2024) Pérez Calderón, Juan Pablo; Giraldo Hernández, Gina María; Pineda Toro, Oscar MauricioThe art of selling is considered one of the most fruitful activities in history, going from bartering to the current economic model, with the concepts of exchanging and selling being immersed in the existence of human beings. The development of marketing, media and technology, has led companies to perform positively in the markets, which is why marketing departments are increasingly gaining value, becoming extremely important for companies. Going deeper into the topic, we find that one of the sectors with the highest rate of delay in the implementation of technology and marketing is the steel sector, which is a strong link in construction where together they are of great importance in the economy of a country. In Colombia, the steel sector corresponds to 2,4 % (Semana, 2023) of the GDP and the construction sector, which is strongly linked to the steel sector, represents 17,6 % of the GDP; Together they represent 20 % of the total Colombian GDP. (Camacol, 2021) The steel market, although it is not one of the sectors with the highest record of business creation, is a very competitive sector and for this reason they are one of those that in the last decade have sought to implement marketing departments into their organizational structures to improve their sales in an exponential form. Sources such as newspapers, websites and union blogs were consulted, among which I highlight Portafolio, Statista, Scope, Camacol, DANE, Camacero, among others, which contribute to the conclusion that a marketing department is extremely important to have bringing to the company better results and performance, especially in their incomes, and in addition, bringing strategic order to the companies.Ítem Implementation of product lifecycle management tools using enterprise integration engineering and action-research(TAYLOR & FRANCIS LTD, 2010-01-01) Penaranda, N.; Mejia, R.; Romero, D.; Molina, A.; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ingeniería de Diseño (GRID)This paper describes how enterprise integration engineering (EIE) and action-research (A-R) can be used to support the implementation of product lifecycle management (PLM) tools. The EIE concept is used to align the corporate strategies with the use of PLM technologies in order to impact the key performance indicators (KPIs) in the enterprise. An EIE reference framework is proposed to define strategies, evaluate performance measures, design/re-design processes and establish the enabling tools and technologies to support the enterprise strategies, while A-R is proposed to guide the PLM tools implementation at various stages of the product development process. An industrial application is described to demonstrate the benefits of applying EIE, A-R and PLM in an enterprise. © 2010 Taylor & Francis.Ítem Optimization of the asset management process in the education sector : case study a chilled water plant(Universidad EAFIT, 2021) Jiménez Arango, Carlos Alberto; Dueñas Ramírez, Leidy Marcela
