CHP (combined heat and power) retrofit for a large MED-TVC (multiple effect distillation along with thermal vapour compression) desalination plant: H…
2016
Abstract Integrated power plants in “dual purpose” configuration may represent a viable option for energy cost abatement of desalted water produced by MED-TVC (Multiple Effect Distillation along with Thermal Vapour Compression). In this paper an existing large MED-TVC plant with a 36,000 m 3 /day capacity is studied: a plant retrofit is designed, based on a steam power plant with condensation and steam extraction used to drive the steam ejector. As the plant operates in CHP (Combined Heat and Power) mode, the possibility to assess the integrated “CHP + MED-TVC” as high efficiency cogeneration according to Directive 2004/8/EC is discussed. Based on a model developed in Engineering Equation S…
Energy and environmental assessment of residual bio-wastes management strategies
2021
Abstract This paper assesses the potential energy and environmental impacts of an anaerobic digester coupled with a combined heat and power plant powered with bio-wastes from the agri-food sector. The analysis is carried out through the Life Cycle Assessment methodology following a “cradle-to-grave” approach and is based mostly on primary data. The anaerobic digester - combined heat and power plant is analysed considering a twofold perspective: one more energy – oriented where the main function of the system is to generate renewable electricity and a waste – oriented one in which the main function is treating bio-wastes. In addition, the environmental indirect effects related to potential c…
Ev charging station at university campus
2017
This paper faces the technical and economic challenges related to the design of a green recharge area for electric vehicles at the Campus of Palermo, Italy, with the aim of reduce both costs and pollution connected to the charging process. Based on the behaviour of the student population, the electrical load is identified and two possible solutions are evaluated to manage the peak load: an orientation of the panels increasing the power at defined time and the use of a storage system. The main strength and weakness points of two systems are investigated by taking into account the Levelized Cost of Energy (LCOE), which reaches 75.3 â¬/MWh for the orientation of panel and 103 â¬/MWh for stor…
Technological performances upgrading and rehabilitation of building heritage inside the historic centre of Palermo
2021
The recovery of building heritage through the containment of carbon emissions is one of the strategies pursued by the city of Palermo. This design approach becomes more paradigmatic when it’s referred to sensitive and historic buildings or urban areas, having an international interest or involved in participatory projects for the Mediterranean city, well beyond the attention that citizens attest to them. We would analyse the Volta electrical Power Station, inside the harbour area and near the Castello a mare, interested by the overall rehabilitation of Palermo waterfront. This building qualifies itself, through a retrofit hypothesis proposed by the authors of this essay, as a significant ex…
Integration of DEMO hazard piping into the tokamak building
2021
Abstract Because of the complexity of the design of a Fusion Power Plant like the EU DEMOnstration power plant the study of the plant layout must proceed in parallel with the design of the major systems. This is necessary to ensure that the design of the plant incorporates from the very beginning sound considerations on: • Safety and licensing, • Personnel security in context with operation and maintenance, • Adequate plant availability, and • Safe performance operation including delivery of few hundred MW net electric power to the electrical grid. Though it is a process of trial and change that follows the design evolution, this approach allows a better and continuous control of the numero…
Helios and Aeolus
2012
In summer it’s always hot in the Big Apple, but the summer of 2003 had been especially sweltering. Temperatures had been around 35oC during all the month, with humidity approaching one hundred percent. The higher the temperature, the lower the New Yorkers’ thermostats, up to the point where you needed a sweater at the office, while outside delivery men, mail carriers and peddlers had to suffer the heat, together with the tourists brave enough to venture through the smoldering avenues.
Fuel for commercial politics: the nucleus of early commercial proliferation of atomic energy in three acts
2020
Historical research into the nuclear industry has focussed upon military and commercial aspects of the technology whilst ignoring fuel. This article discusses nuclear fuel, the resource at the centre of the industry and the role superpower politics played in its supply. Starting with the context of superpower competition, we examine the spread of nuclear technology from its beginnings in post-war Britain via West Germany in the 1950s to Finland in the 1960s and 1970s. We demonstrate that each country had varied interests affecting the choice of nuclear fuel for early energy projects; British fuel choices were constrained by its weapons programme and Germany needed legitimacy in the face of …
Analysis of Protected Accidental Transients in the EFIT Reactor With the RELAP5 Thermal-Hydraulic Code
2008
The European Facility for Industrial Transmutation (EFIT) is aimed at demonstrating the feasibility of transmutation process through the Accelerator Driven System (ADS) route on an industrial scale. The conceptual design of this reactor of about 400 MW thermal power is under development in the frame of the European EUROTRANS Integrated Project of the EURATOM Sixth Framework Program (FP6). EFIT is a pool-type reactor cooled by forced circulation of lead in the primary system where the heat is removed by steam generators installed inside the reactor vessel. The reactor power is sustained by a spallation neutron source supplied by a proton beam impinging on a lead target at the core centre. A …
An exact algorithm for preventive maintenance planning of series-parallel systems
2009
Reliability is a meaningful parameter in assessing the performance of systems such as chemical processing facilities, power plant, aircrafts, ships, etc. In the literature, reliability optimization is widely considered during the system design phase and it is carried out by an opportune selection of both system components and redundancy. On the other hand, the problem of maintaining a required level of reliability by an opportune maintenance policy has been poorly examined. The paper tackles this problem for a system whose major components can be maintained only during a planned system downtime. An exact algorithm is proposed in order to single out the set of components that must be maintai…
Core and Shell: facciate storiche e nuovi edifici. Il caso dell’ex Chelsea and Fulham Power Station a Londra
2022
The maintenance of the façade(s) is one of the most common solutions – in countries where this intervention is allowed – which can also guarantee the “preservation” of the existing built herit- age, as well as the construction of new “zero land consumption buildings”. The English term used to identify this area of work is Façadism. The paper analyses a perfect example attributable to this area of work that is being implement- ed on the former Chelsea and Fulham Power Station in London. The refurbishment project, in the construction phase, was instructed to Midgard Design Service Ltd (Design Department of the Irish construction company JRL Group Limited) which will transform the entire area …
