Publicación Desarrollo de la estrategia de reducción de huella de carbono de Nitrofert S.A.S(Universidad EAFIT, 2024) Obando Mera, Carolina; Hernández del Valle, Maira Fernanda; Echeverry, Luis Miguel; Grupo Empresarial Nitrofert; Enel Colombia S.A ESPÍtem Design of an absorption tower for a laboratory scale CO2 capture plant(Universidad EAFIT, 2021) Herrera Meneses, Michel Alejandra; Román Restrepo, Valeria; Builes Toro, SantiagoCarbon dioxide (CO2) is the main greenhouse gas in the earth’s atmosphere. The current concentration levels of CO2 in the atmosphere contribute to generate irreversible changes in the climate, sea level and the environment. Due to the highly industrialized economy, for today's society it will not be possible, in the mid-term, to stop these CO2 emissions without serious economic and social consequences. Therefore, it is necessary to implement several strategies to reduce CO2 emissions, for instance integrated CO2 capture systems that are efficient and economically viable. Strategies such as carbon capture and storage can used to reduce the impact of CO2 emissions on the global climate to an acceptable level. Reactive absorption with aqueous solutions of amines in an absorber/stripper loop is the most mature technology for CO2 capture from existing plants. Therefore, it is proposed to design an absorption tower at laboratory scale in stainless-steel due to its stability and resistance to corrosion for the capture of CO2 using monoethanolamine. This requires the assessment of the best model for describing an absorption tower at laboratory scale by comparing different models and simulations programs to determine the most appropriate one for design at laboratory scale. The model implemented in Python absorption tower design was chosen over the commercial simulators, resulting in a 10 mm Raschig ceramic ring packing, a CO2 removal rate of 80%, an internal diameter of 21.7 mm and a packing height of 400 mm.Publicación Estudio de factibilidad de un emprendimiento sobre la innovación en la comercialización de bonos de Carbono en el Valle de Aburrá y Oriente cercano, para contribuir con la mitigación de los daños de gases de efecto invernadero(Universidad EAFIT, 2022) Acevedo Martelo, Sebastián; Areiza Valencia, Juan Ramón; Salazar Gómez, Francisco Javier; Giraldo Hernández, Gina MaríaDue to the human ordinary and daily activities the environment suffered substantial losses, especially in the atmosphere. The detriment has been caused by the effects of the actual energetical base that relies on fossil fuels, which releases carbon dioxide particles. Thus big initiatives such as the carbon footprint offset programs had been developed through the green bonds, in order to mitigate the climate change. While there’s an effective solution in order to mitigate the environmental impact in the atmosphere such as the green/carbon bonds, the public doesn’t easily and frequently access to those carbon footprint offset programs. It is due especially because there isn’t a sufficient knowledge of these programs. Furthermore, it doesn’t exist a vehicle which centralizes and facilitates the access to the carbon offset market. In this respect, even if there’s a green bond market -Which isn’t accessible to all the public at all- it is intended to formulate and evaluate the feasibility of an entrepreneurship that would innovate the commercialization of the green bonds. These feasibility study will address the legal, administrative, technical, financial and commercial aspects of the project.Publicación Estudio de viabilidad de la implementación en INDELPA S.A. de un sistema de energía solar térmica para calentamiento de agua en el tratamiento químico de superficies(Universidad EAFIT, 2014) González Ospina, Diana Patricia; Uribe de Correa, Beatríz Amparo; Gómez Salazar, Elkin ArcesioEl continuo desgaste del ecosistema de nuestro planeta y el agotamiento a mediano plazo de las reservas de combustibles fósiles como gas, petróleo y carbón, son las consecuencias de mayor impacto del actual sistema energético mundial que se fundamenta en el uso intenso de estas fuentes de energía -- Es por esto que se hace necesaria la implementación de energías alternativas que sean amigables con el medio ambiente, y aún más en los procesos industriales; entre estas fuentes alternativas se encuentra la energía solar, que cuenta con la potencia más alta de las energías renovables -- La instauración de fuentes no convencionales de energía ha requerido acciones de apoyo que las hagan viables -- El gobierno colombiano ha dispuesto recursos de cofinanciación para las pymes que desarrollen proyectos que involucren energías limpias; adicionalmente, en el mercado financiero se encuentran algunas herramientas de financiación como el leasing que podrían servir para la implementación de este proyecto en caso de determinarse su viabilidad -- El análisis de viabilidad de la implementación de la energía solar como fuente alternativa al interior del proceso de tratamiento químico de superficies en la empresa metalmecánica INDELPA S. A. es el objeto de este estudio -- Dicho proceso metalmecánico requiere calentamiento de grandes volúmenes de agua, lo que implica en el momento consumos elevados de gas naturalPublicación Implicaciones del cambio climático en las operaciones de los puertos en Colombia(Universidad EAFIT, 2024) Palacio Machado, María Camila; Pineda Toro, Oscar Maricio; Giraldo Hernández, Gina MaríaThis research work seeks to identify the effect that climate change has had on the operations of port areas in Colombia. For this purpose, an initial review of the concept of climate, its causes and the implications generated is proposed, not only in the economic and operational context but also in the social aspect. Subsequently, a characterization of the environment is made to recognize the vulnerability of the variables, how they interact with each other in the ecosystem and to identify what procedures exist to manage the threats that exist in the logistics processes. In this case, the conceptualization with respect to seaports becomes an important aspect to determine the benefits generated in the social, economic and environmental spheres. Finally, the impacts on the operations system are analyzed and a reference framework is described with various strategies implemented to help mitigate the impacts of climate change when these are negative or unfavorable.Ítem Políticas mundiales para la disminución de emisión de CO2 y sus posibles efectos en el precio de los hidrocarburos en la balanza comercial de Colombia(Universidad Eafit, 2020) Herrera Cuervo, Tomás; Rodriguez Padron, Juan Ignacio; Goda, ThomasHuman progress has led to an increased of greenhouse gas emissions, which have had negative effects on people's health and economy impacts. As a consequence of this, different instruments have been implemented to reduce CO2 emissions globally, which can affect the demand and price of hydrocarbons. The purpose of this work is to see how Colombia's trade balance might look in the future after the global implementation of these instruments to reduce CO2 emissions.Publicación Sustainable hospitality in the Sierra Nevada de Santa Marta: how to develop a sustainable hospitality industry in the Sierra Nevada de Santa Marta, Colombia taking the case of Turtle Bay Resort in Hawai'i as a model(Universidad EAFIT, 2014) Montúfar Fandiño, Enrique Alberto; Díaz Vásquez, Juan CarlosThis research attempts to provide necessary context in order to present recommendationsand to evaluate the need for the development of the sustainable hospitality industry in the Sierra Nevada de Santa Marta -- This research presents sustainable hospitality as an alternative for economic development, based on the analysis of data gathered at Turtle Bay Resort in Hawai’i and validated by a literature review -- This analysis focuses mainly on the management of important resources: energy, water and waste, following sustainable principles like the ones presented by systems theories, such as Cradle to Cradle (Braungart, McDonough & Bollinger, 2006) and Blue Economy (Dijk, Tenpierik & Dobbelsteen, 2013) -- Sustainable hospitality1 provides an eco-effective alternative, for the sustainable economic development of the Sierra Nevada de Santa Marta Region -- The world has changed -- Today, we live in a world with highly competitive markets and volatile economic environments -- No organization, especially those that rely on limited or declining natural resources, can operate the way they did a decade ago (COSO, 2013) -- The 20th century taught us that economic growth does not necessarily mean social development, and that unbounded growth is unsustainable -- Growing energy demand and damaging greenhouse gas (GHG) emissions, such as CO2 (Carbon dioxide) and CH4 (Methane), reflect the cost and unsustainable requirements of the system that arose from the industrial revolution, powered initially by coal and later by oil (Peura, 2012) -- Economic development must be sustainable and alternatives to an ever growing economy must be explored (Jackson, 2009) -- The time framework presented in this research, from the industrial revolution to climate change (Jackson, 2009) presents arguments for dealing with high energy demand and negative environmental impact -- In particular considering the current context of growing inequality between (Müller-Steinhagen and Nitsch -- 2005) and within countries, mainly in those with relatively recent economic growth, based in many cases on extractive industries and other unsustainable resource intensive activities (Fung, 2009) -- As is the case for Colombia in which sustainable hospitality principles are yet to be assimilated and implemented in its complex socio-economic context -- Sustainable hospitality focuses on reducing and when possible eliminating the negative environmental, social and economic impact resulting from the normal operation of the traditional hospitality sector (EPA, 2013) -- Society needs an economy that stimulates technologies that improve the system -- The hospitality industry can benefit from the rising demand around the world for these technological and ecological solutions by providing clients a sustainable service, for the good of the company’s bottom line, the guests, the employees, clients, suppliers and the surrounding communityÍtem Tendencias normativas en materia de generación de energía a partir de fuentes renovables no convencionales: razones y manifestaciones de una transformación jurídica(Universidad EAFIT, 2014) Velásquez Restrepo, Daniel; Correa Pérez, Simón; Hernández Betancur, Luis FernandoEn este trabajo se ha analizado la importancia de introducir a la matriz energética nacional fuentes renovables no convencionales, las cuales permitan avanzar al país en dirección a la mitigación y adaptación del cambio climático -- Igualmente, se ha hecho un recorrido por diversos instrumentos institucionales y/o jurídicos como documentos CONPES, planes energéticos nacionales y diversas leyes, que modelan la política pública en cuanto a generación de energía eléctrica y que influyen, directa o indirectamente, en la capacidad de penetración de la tecnología necesaria para diversificar la matriz energética -- Ambas perspectivas, permiten definir un panorama muy específico en Colombia, el cual contrapone las necesidades propias del territorio frente al cambio climático con las medidas existentes, suficientes o insuficientes, para satisfacer dichas necesidadesPublicación Towards a low-emission economy : environmental policies and electricity transition(Universidad EAFIT, 2021) González Auhing, Marcos Emmanuel; Hurtado Rendón, Álvaro Arturo; Botero García, Jesús AlonsoÍtem Virtual validation of an automated greenhouse irrigation model based on a systems engineering approach(2014-03-27) Mejía Gutiérrez, Ricardo; Zuluaga Holguín, Daniel; Carvajal Arango, Ricardo; Universidad EAFIT.
