Towards practical solutions for energy efficiency of large-scale industrial sites
This thesis investigates a set of advanced topics inspired from the heat integration and the pinch technology, all tied around the challenge of identifying energy savings in large-scale chemical industrial plants. In search for a general-purpose methodolog ...
EPFL2015The role of process integration techniques in the thermo-economic optimization of energy conversion systems
François Maréchal, Laurence Tock
Within the goal of reducing greenhouse gas emissions and supplying sustainable energy, complex integrated energy conversion systems have to be designed by taking into account thermodynamic, economic and environmental considerations simultaneously. The proc ...
2013Quantitative feasibility study of magnetocaloric energy conversion utilizing industrial waste heat
Didier Albert Simon Vuarnoz, Cyrill Gonin
The main objective of this theoretical study was to investigate under which conditions a magnetic energy conversion device (MECD) - utilizing industrial waste heat - is economically feasible. Furthermore, it was evaluated if magnetic energy conversion (MCE ...
2012THERMAL STORAGE AIMING AT INCREASING THE SHARE OF USED HEAT REJECTED FROM A COOLING PROCESS
Neighbourhood energy concepts for mixed industrial and commercial sites can be developed by applying energy integration techniques. This study presents an application of these techniques on a concrete site (RTA facility in Vienna, Austria), focussing on th ...
2012Theoretical and Experimental Study of a Thermally Driven Heat Pump Based on a Double Organic Rankine Cycle
Nowadays, one of the main alternatives for a more rational use of energy in heating applications is the heat pumping technologies. The market is dominated by two kinds of heat pump systems: the electrically driven vapor compression heat pumps (EHP), which ...
EPFL2012Polymer spiral film gas-liquid heat exchanger for waste heat recovery in exhaust gases
In this master thesis report the development of an innovative spiral heat exchanger based on polymer materials is described. Building prototypes, erection of a test bench and firsts tests of the heat exchanger are presented. The heat exchanger prototype su ...
2012Conceptual design of a thermo-electrical energy storage system based on heat integration of thermodynamic cycles – Part A: Methodology and base case
This paper analyses the thermodynamic performance and proposes different energy integration schemes for a methanol absorption based acid gas removal process, namely the Rectisol® process specifically designed for the selective removal of H2S and CO2 from c ...
Elsevier2012Thermoeconomic Analysis of a Solar Enhanced Energy Storage Concept Based on Thermodynamic Cycles
Large scale energy storage may play an increasingly important role in the power generation and distribution sector, especially when large shares of renewable energies will have to be integrated into the electrical grid. Up to now pumped-hydro is the only t ...
Pergamon-Elsevier Science Ltd2011Phase change behavior of ammonia-water mixtures in corrugated plate heat exchangers
The present report describes the work realized in the frame of a Mas- ter Pro ject in collaboration between the company EnBW Energie Baden- Württemberg AG (Germany) and the Section of Mechanical Engineering of the Swiss Institute of Technology of Lausanne ...
2011Evidence for Thermal Spin-Transfer Torque
Jean-Philippe Ansermet, Haiming Yu, Simon Granville
Large heat currents are obtained in Co/Cu/Co spin valves positioned at the middle of Cu nanowires. The second harmonic voltage response to an applied current is used to investigate the effect of the heat current on the switching of the spin valves. Both th ...
