Proyecto de almacenamiento de productos químicos en la localidad de Ribarroja del Turia (Valencia)

[ES] El trabajo se basa en un proyecto de almacenamiento de productos químicos como consecuencia del traslado de una empresa de cosméticos a Ribarroja del Turia (Valencia). Para el desarrollo del proyecto es necesario el estudio de los productos, a nivel individual y en conjunto. Para ello clasificarán los productos, y se realizará el diseño del parque de almacenamiento sujeto a la normativa vigente y a los requerimientos del cliente. Para un correcto diseño de la instalación de almacenamiento la normativa establece unas condiciones: la existencia de pavimento en la planta industrial, cerramientos, venteos y alivio de presión en los depósitos. Además, se garantiza la seguridad de la instalación por la implementación de sistemas de protección contra el fuego y contra el rayo. Para reforzar la seguridad de los trabajadores y el buen mantenimiento de las instalaciones, se darán unas instrucciones de uso y conservación. Por último, se presentará al promotor el presupuesto de la inversión.[EN] The work is based on a project to store chemical products as a result of the transfer of a cosmetic company to Ribarroja del Turia (Valencia). For the development of the project it is necessary to study the products, individually and in conjuntion. For this they will classify the products, and the design of the storage park will be carried out subject to the current regulations and to the client's requirements. For a correct design of the storage installation the regulation establishes conditions: the existence of pavement in the industrial plant, enclosures, vents and relief of pressure in the deposits. In addition, the security of the installation is guaranteed by the implementation of fire and lightning protection systems. In order to strengthen the safety of the workers and the good maintenance of the facilities, instructions for use and conservation will be given. Finally, the investment budget will be presented to the developer.Martínez Reverte, I. (2018).

EVALUACIÓN DE ALTERNATIVAS DE ABASTECIMIENTO ENERGÉTICO A PARTIR DE PILAS DE COMBUSTIBLE EN L'ILLA PERDUDA. SUMINISTRO A 4194 VIVIENDAS CON UNA POTENCIA INSTALADA APROXIMADA DE 4 MW

[ES] El presente trabajo desarrolla un estudio sobre distintas formas de abastecimiento energético a partir de pilas de combustible en el barrio de L¿illa Perduda, situado en Valencia. Una vez realizado dicho estudio, en el cual se compararán diversas alternativas, se escogerá la más adecuada en función de diversos criterios. Para la evaluación se dimensiona cada tecnología de forma que llegue a proveer a las viviendas seleccionadas. Una vez seleccionada la tecnología adecuada, se realiza un diseño de la instalación completa para terminar la evaluación técnica, económica, ambiental, legal, etc. Para poder realizar el proyecto y poder comprobar las mejoras que supone cada alternativa estudiada, se deben conocer las características energéticas iniciales que mantienen los edificios actualmente. Dado que no se puede conocer con exactitud la forma de suministro que tiene cada vivienda, se establecerán dichas características a partir de las tipologías constructivas del proyecto TABULA-EPISCOPE del Instituto Valenciano de la Edificación (IVE), que las caracteriza según el periodo de construcción de cada edificio. El barrio objeto de estudio pertenece al distrito de Algirós, en el este de la ciudad. Tiene una superficie total de 0,232 km2 poblada por 9360 habitantes, por lo que su densidad de ocupación es elevada. La mayor parte de los edificios que componen L¿illa Perduda se construyeron en los años 60, aunque se ha seguido ampliando hasta esta última década. En un primer estudio se han identificado 4194 viviendas y la oportunidad de instalar pilas de combustible por hasta 4 MW de potencia.[EN] This work develops a study on different forms of energy supply from fuel cells in the L¿illa Perduda neighborhood, located in Valencia. Once this study has been carried out, in which various alternatives will be compared, the most appropriate will be chosen based on various criteria. For the evaluation, each technology is dimensioned in such a way as to supply the selected homes. Once the appropriate technology has been selected, a complete installation design is carried out to complete the technical, economic, environmental, legal evaluation, etc. In order to carry out the project and be able to verify the improvements that each studied alternative implies, the initial energy characteristics that the buildings currently maintain must be known. Given that it is not possible to know exactly the form of supply that each house has, these characteristics will be established based on the construction typologies of the TABULA-EPISCOPE project of the Valencian Building Institute (IVE), which characterizes them according to the period of construction of each building. The neighborhood under study belongs to the Algirós district, in the east of the city. It has a total area of 0.232 km2 populated by 9,360 inhabitants, so its occupancy density is high. Most of the buildings that make up L¿illa Perduda were built in the 1960s, although it has continued to expand until this last decade. In a first study, 4194 homes and the opportunity to install fuel cells for up to 4 MW of power have been identified.Martínez Reverte, I. (2021).

Evaluation of Alternatives for Energy Supply from fuel Cells in Compact Cities in the Mediterranean Climate. Case Study: City of Valencia

[EN] A study of energy supply alternatives was carried out based on a cogeneration fuel cell system fed from the natural gas network of compact Mediterranean cities. As a case study it was applied to the residential energy demands of the L'Illa Perduda neighbourhood, located in the east of the city of Valencia and consisting of 4194 residential cells. In total, eight different alternatives were studied according to the load curve, the power of the system, the mode of operation and the distribution of the fuel cells. In this way, the advantages and disadvantages of each configuration were found. This information, together with the previous study of the energy characteristics of the neighbourhood, enabled selection of the most promising configuration and to decide whether or not to recommend investment. The chosen configuration was a centralised system of phosphoric acid fuel cells in cogeneration, with approximately 4 MW of thermal power and an operating mode that varied according to the outside temperature. In this way, when heating is required, the plant adjusts its production to the thermal demand, and when cooling is required, the plant follows the electrical demand. This configuration presented the best energy results, as it achieved good coverage of thermal (62.5%) and electrical (88.1%) demands with good primary energy savings (28.36 GWh/year). However, due to the high power of the system and low maturity (i.e., high costs) of this technology, would be necessary to make a large initial economic investment of 15.2 Meuro.This research was funded by Catedra de Transicion Energetica Urbana (UPV-Las NavesFVCiE).
