Theoretical analysis of steam generation methods - Energy, CO 2 emission, and cost analysis

Jürg Alexander Schiffmann

A theoretical case study on steam generation has been performed. Different methods of producing steam by vapour compression, direct electrical heating, gas heating, heat pumping, use of waste heat, and a mixture thereof, were theoretically analysed. The fi ...

Optimal Operations and Resilient Investments in Steam Networks

François Maréchal, Greta Martha Van Eetvelde, Laurent Gabriel Félix Alexandre Stéphane Bungener

Steam is a key energy vector for industrial sites, most commonly used for process heating and cooling, cogeneration of heat and mechanical power as a motive fluid or for stripping. Steam networks are used to carry steam from producers to consumers and betw ...

A method for taking into account seasonal storage in a district energy system optimisation problem

François Maréchal, Jessen Page, Jean-Loup Sylvain Robineau

In this work, a method for taking into account seasonal storage in an energy optimisation problem is developed. A master-slave optimisation procedure is applied, in which the master optimisation is an evolutionary algorithm, while the slave optimisation is ...

Environmental, Energetic and Economic Evaluation of Implementing a Supercritical Fluid-Based Nanocellulose Production Process in a Sugarcane Biorefinery

François Maréchal, Juliana Queiroz Albarelli

Nanocellulose, which is a disintegration product of plant cellulose, has recently come to public attention because of its great mechanical properties combined with renewability and biodegradability. From an environmental point-of-view, nanocellulose has sh ...

Robust and Gain-Scheduled PID Controller Design for Condensing Boilers by Linear Programming

Alireza Karimi, Vinicius De Oliveira

This paper addresses the water temperature control in condensing domestic boilers. The main challenge of this process under the controller design perspective is the fact that the dynamics of condensing boilers are strongly affected by the demanded water fl ...

Performance and Profitability Perspectives of a CO2 based District Energy Network in Geneva’s City Center

Daniel Favrat, Céline Weber, Samuel Henchoz

A new type of district energy network capable of providing simultaneously heating and cooling is being investigated. It is based on the use of CO2 as a heat transfer fluid by taking advantage of the latent heat of vaporization, to store and transfer heat a ...

Multi-Scale Modelling of a Solar Reactor for the High-Temperature Step of a Sulphur-Iodine-Based Water Splitting Cycle

Sophia Haussener, Aldo Steinfeld

The 3-step sulphur-iodine-based thermochemical cycle for splitting water is considered. The high-temperature step consists of the evaporation, decomposition, and reduction of H2SO4 to SO2 using concentrated solar process heat. This step is followed by the ...
