A dual representation for targeting process retrofit, application to a pulp and paper process

A method for the analysis of process energy requirements has been used to identify in an early design stage the potential process retrofit measures in an integrated pulp and paper mill. The minimum energy requirements (MER) of the process were computed by ...

Evaluation of a building using the emergy method

Emergy (spelled with an m) is the energy of one kind, usually solar energy, which is required to make a service or product. The yearly emergy consumption/production of a building is evaluated considering the Solar Energy Laboratory (LESO) building on the c ...

Analysis of free energy change and thermodynamic feasibility in a genome scale metabolic model

Vassily Hatzimanikatis

With the sequencing and annotation of the entire genomes of numerous microorganisms has come the advent of the genome scale metabolic models such as the iJR904 model of E. coli from Palsson and coworkers. Metabolic flux anal. (MFA) is widely employed to ge ...

Spin dynamics in the mixed phase of La2-xSrxCuO4 (x=0.10, x=0.17)

Henrik Moodysson Rønnow, Joël Mesot

We present an inelastic neutron scattering study of the spin dynamics in the mixed phase of the high-T-c superconductor La2-xSrxCuO4, In the overdoped regime (x = 0. 17, T-c = 37 K) the application of a magnetic field induces a spectral weight redistributi ...

Green heating system: characteristics and illustration with multi-criteria optimization of an integrated energy system

François Maréchal, Daniel Favrat, Hongtao Li, Meinrad Bürer

The characteristics of the 'Green Heating System', synonymous with 'Environmentally Friendly Heating System', is academically defined from the total energy systems' point of view, using the concept of 'reversible mode of heating' under the current and futu ...

Biogas exploitation by SOFC

Daniel Favrat, Jan Van Herle

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 ...

Strain-induced diffuse dielectric anomaly and critical point in perovskite ferroelectric thin films

Nava Setter, Paul Muralt, Alexander Tagantsev

It is shown that a strong but diffuse dielectric anomaly, commonly expected only in disordered ferroelectrics, may be inherent in strained and defect-free perovskite ferroelectric thin films. The origin of this unusual anomaly, which was never predicted fo ...

ONLINE ENTHALPY MEASUREMENT METHOD FOR PHASE CHANGE SLURRIES

Didier Albert Simon Vuarnoz

To measure enthalpy densities, respectively overall specific heats, frequently the differential scanning thermal analysisis (DSC) is applied. Other useful methods are also available, but all of them have disadvantages. Therefore, an alternative measurement ...

Process Integration: From Continuous to Batch Processes.

Daniel Favrat, Pierre Krummenacher

Among the structure independent approaches of process integration, pinch technology has been shown for continuous processes to be extremely powerful to develop energy efficient processes and enhance synergic effects within and between processes. The earlie ...

Thermoeconomic Analysis of Advanced Solar-Fossil Combined Power Plants

Daniel Favrat, El Hadj Malick Kane

Hybrid solar thermal power plants (with parabolic trough type of solar collectors) featuring gas burners and Rankine steam cycles have been successfully demonstrated by California's Solar Electric Generating System (SEGS). This system has been proven to be ...
