Innovative design and multi-objective optimization of hybrid reverse osmosis and multi-stage flash desalination plants

François Maréchal, François Vince

The selection of an hybrid MSF/RO desalination plant depends on many factors, such as capital costs, electricity consumption, water conversion rate and local requirements. In order to provide the necessary information for the decision process, stand-alone ...

Methodology for the optimal thermo-economic, multi-objective design of thermochemical fuel production from biomass

Martin Gassner, François Maréchal

This paper addresses a methodology for the optimal conceptual design of thermochemical fuel production processes from biomass. A decomposed modelling approach with separate energy-flow, energy-integration and economic models is presented and coupled to mul ...

The challenge of introducing an exergy indicator in a local low on energy

Daniel Favrat, François Maréchal

Extending the idea of exergy to practitioners and policy makers is still a major challenge. Recently the "Canton of Geneva" in Switzerland introduced a new law governing the procedures of attribution of building permits for new or retrofitted city areas. A ...

Methodology for process energy analysis: application to a sulfite wood pulping

François Maréchal, Zoé Périn-Levasseur

Creating a consistent thermodynamic database is the first step required to perform a process integration study. A method based on the use of data identification and reconciliation has been developed to model the mass and the energy balances of a pulp and p ...

Thermo economic analysis for the optimal conceptual design of biomass gasification energy conversion systems

Martin Gassner, François Maréchal, David Brown

This study addresses the thermo economic assessment of a biomass gasification, gas cleaning and energy conversion process, with particular attention given to tar control and the communication of the process design rationale. Product distributions were esti ...

Thermo-economic optimisation of the integration of electrolysis in a wood to methane process

Martin Gassner, François Maréchal

Converting wood to grid quality methane allows to distribute a CO2 free, renewable enery resource in a conventional energy distribution system and use it in transportation applications. Using a previously developed thermo–economic process model for thermoc ...

Can steam play a role in low to medium power from low temperature heat?

Daniel Favrat, Jonathan Demierre, François Maréchal

Rankine cycles for low to medium power and low temperature heat using water as working fluid, were almost written off. The main arguments speaking against them are reviewed in this paper and the conceptual design of the equipment entirely revisited. An adv ...

A Model for Simulating the Thermal and Electrical Production of Small-Scale Solid-Oxide Fuel Cell Cogeneration Systems within Building Simulation Programs

François Maréchal

A new model for predicting the thermal and electrical performance of solid-oxide fuel cell(SOFC) cogeneration devices for residential buildings has been developed and demonstrated. This is a system-level model that considers the thermodynamic performance o ...

Enhancing the quality of energy services in urban areas by means of renewable energy technologies and information and communication technologies in energy networks: issues, challenges and opportunities

Gaëtan Cherix, François Maréchal, Matthias Finger

Urban areas are characterized by a high concentration of economic and social activities. As a consequence, residential, commercial or industrial activities require an enormous rate of resources consumption. This can lead to environmentally-related problems ...

Advanced Power Plant Design Methodology using Process Integration and Multi-Objective Thermo-Economic Optimisation

Daniel Favrat, Raffaele Bolliger, François Maréchal

Thermo-economic modelling techniques are well known techniques to optimise power plant designs. These methods are usually based on the definition of a superstructure that includes the major options of the design. If this approach has proved to be appropria ...

Network synthesis for district heating with multiple heat plants

Daniel Favrat, François Maréchal, Céline Weber

In this paper the first results of a new method for the configuration of district energy systems are presented. District energy systems are believed to help decreasing the CO2-emissions due to energy services (heating, cooling, electricity and hot water), ...

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

François Maréchal, David Brown

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 ...
