The magnet feeders for the European DEMO fusion reactor: Conceptual design and recent advances

Rainer Wesche, Roberto Guarino, Frédéric Michel

The magnet feeders are part of the critical systems of a fusion reactor since they represent the interface between the in-cryostat components at 4.5 K and the room-temperature cryogenic plant and power supply. The European DEMO tokamak foresees 16 toroidal ...

Virtual Sector Profiles for Innovation Sharing in Process Industry – Sector 01: Chemicals

François Maréchal, Ivan Daniel Kantor, Greta Martha Van Eetvelde, Laurent Gabriel Félix Alexandre Stéphane Bungener, Elfie Marie Méchaussie

Production data in process industry are proprietary to a company since they are key to the process design and technology expertise. However, data confidentiality restrains industry from sharing results and advancing developments in and across process secto ...

Integrating Rate Based Models into a Multi-Objective Process Design & Optimisation Framework using Surrogate Models

Levent Sinan Teske

In the development of energy and chemical processes, the process engineers extensively apply computer aided methods to design & optimise these processes and corresponding process units. Such applications are multi-scale modelling and multi-objective optimi ...

Atmospheric amines and ammonia measured with a chemical ionization mass spectrometer (CIMS)

Athanasios Nenes, Satoshi Takahama, Giulia Ruggeri, Hairun Guo

We report measurements of ambient amines and ammonia with a fast response chemical ionization mass spectrometer (CIMS) in a southeastern US forest and a moderately polluted midwestern site during the summer. At the forest site, mostly C3-amines (from pptv ...

Integrating rate based models into multi-objective optimisation of process designs using surrogate models

François Maréchal, Levent Sinan Teske

Multi-objective optimisation (MOO) of super-structured process designs are expensive in CPU- time because of the high number of potential configurations and operation conditions to be calculated. Thus single process units are generally represented by simpl ...

The 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 ...

Application of Exergy Analysis in Energy Requirements Assay of the Typical Process Unit Operations of Chemical Industries

Amélie Courjon

This project proposes a method based on exergy analysis for considering energy efficiency problems. Because exergy is not a concept frequently used by industrials attention has been paid to go through what is exergy and how it can be so useful to enhance t ...
