Process integration and opportunities for heat pumps in industrial processes
Graph Chatbot
Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
In 1998, the Board of the Swiss Federal Institute of Technology established the challenging vision of the 2000 W society. The goal is to reach, for Switzerland by the year 2050, an energy intensity target of 2000 Wyear/year/cap. Referring to a present inte ...
With the push for greater energy conservation, the need for heating and/or power production is being filled by cogeneration facilities. Thus, the search for the best performance at the least cost for such multipurpose plants is made much more difficult by ...
The integration of the utility system with all the plants of an industrial site is a mamor task for targeting the Minimum Cost of the Energy Requirement (MCER). Defining the target in terms of cost rather than in terms of energy introduces the problem of i ...
As energy plays a central role in the world development, it represents as well a major challenge for sustainable development. Today, more than 80% of the primary energy consumption is based on fossil fuels and the share is likely to remain high in the futu ...
Exergy concept combined with pinch based approach are used for studying the optimal integration of energy conversion systems. The analysis first considers the representation of the hot and cold composite curves of the process and defines the energy and the ...
A computer system for the promotion of the rational use of energy in the industry has been developed. It combines the PINCHLENI software developed by the LENI (Laboratory of industrial Energy Systems) of the Swiss Federal Institute of Technology (Lausanne) ...
A new series of iridium(III) mixed ligand complexes TBA[Ir(ppy)2(CN)2] (1), TBA[Ir(ppy)2(NCS)2] (2), TBA[Ir(ppy)2(NCO)2] (3), and [Ir(ppy)2(acac) (4) (ppy = 2-phenylpyridine; acac ...
Biogas as renewable source of energy is underexploited. We extrapolate the potential recoverable from waste streams in the EU-15 to 769 PJ (17.5 Mtoe), of which under 10% is used (1.7 Mtoe). SOFC can promote the valorisation of biogas in small CHP installa ...
The integration of the utility system with all the plants of an industrial site is a mamor task for targeting the Minimum Cost of the Energy Requirement (MCER). Defining the target in terms of cost rather than in terms of energy introduces the problem of i ...
Aerobic chemostat cultures of S. cerevisiae were performed at different diln. rates under energy (glucose) limitation or at various extents of energy excess imposed by a N limitation. Energy excess induced metabolic uncoupling under steady-state conditions ...
