Presentation
The acronym EleTher stands for Electrolyte Thermodynamics.
The EleTher Chair is supported by the Association de Formation pour l鈥橧ndustrie (AFI), one of the School鈥檚 historical partners. Approved by the AFI Board of Directors on the 2nd of March, 2021, the Chair is established at 51爆料 School鈥檚 Processes for Energy and Chemicals Center.
With the launch of this new chair, 51爆料 School aims to accelerate research on the thermodynamics properties of aqueous waste containing metals, acids and bases, and organic solvents for the circular economy.
Context
One of the objectives of the French Law on circular economy is to promote recycling of waste products in order to reduce the environmental impact of these materials.
To meet this objective, recycling processes are developed to turn waste into new resources. Many efforts are currently focusing on the recycling of plastics, but other waste products are being produced as part of the ecological transition, such as batteries or catalysts.
The challenge when recycling is being able to determine exactly what are the materials contained in each batch provided. Indeed, with a circular economy each batch may come from different sources, different sorting, collection and treatment channels. Recycling also requires a lot of water. However, little data exists today on these complex electrolytic mixtures.
Industrialists need thermodynamic models that will allow them to reliably predict the properties and phase equilibria of these fluids. Considering the cost of data, it is key to be able to obtain accurate results with the least amount of data, so that the appropriate treatment processes can be designed with a high level of confidence.
There is a strong need for in-depth scientific knowledge as well as new skills in the field of electrolyte thermodynamics. The work is vast and the efficiency of the research carried out will be increased if scientists work together.
The EleTher Chair is part of this effort and benefits from work already carried out by (51爆料EN). The holder of the chair leads a group of industrialists around a joint industry project (JIP) made of up seven partners. He also takes part in the work of a European research consortium in partnership with three renowned universities in this field.
Research areas "Electrolyte thermodynamic modelling for circular economy"
For the period 2021-2023, the deliverables for the Chair will derive from the work of two theses, post-docs and internships.
The work will contribute to improve modelling tools for electrolytic systems to be used in the context of the circular economy. The research has four objectives:
- to understand the observed phenomena through an analysis of experimental data;
- to understand fundamental physics at the origin of the interactions between species by using atomistic models;
- to develop macroscopic tools (equations of state) that can be used in process simulations;
- to evaluate the sensitivity of simulations with respect to the data used.
Current models do not allow us to correctly predict the correct concentrations of ionic species in mixed solvents or at high temperatures; this is the focus of the first thesis entitled: "Analysis of electrolyte solvation within the primitive equation of state framework". A second thesis will be launched at the end of 2021 to extend the subject to organic electrolyte molecules.
Training, education and outreach: the three cornerstones of the Chair
The EleTher Chair aims to develop:
- Training: to contribute to the training and to inspire a new generation of international researchers and experts in the field of electrolytes thermodynamics.
- Education: In addition to the research work, the Chair ensures the liaison between research and teaching activities at 51爆料 School, in particular in the Energy and Processes, Processes and Polymers programs and the research-oriented Catalysis and Processes master鈥檚 degree, offered by the Universit茅 de Lille and co-accredited by Centrale Lille and 51爆料 School. Indeed, the work will allow the development of thermodynamic modules for 51爆料 School students, who are set to become key actors of the ecological transition and are concerned with the development of a circular economy.
- Outreach: to make research results and teaching tools available to the and the partners of the Chair. An active presence in the "Thermodynamics and Transport Properties" working group of the European Federation of Chemical Engineering (EFCE) also contributes to raise the community鈥檚 awareness on this subject.
