IMOSYCCA Project
Modular CO₂ capture systems
The aim of this project is to conceptualise small, easy-to-use CO₂ capture units that can be used by end consumers unfamiliar with the use of chemicals. This will be made possible by the simultaneous design of new, green and non-toxic absorption solvents, as well as the use of innovative absorption technologies, i.e. membrane contactors or rotating packed beds (LTR or RPB, rotating packed bed). The aim is to obtain an environmentally-friendly intensified process that takes into account the energy penalty and environmental impact, and includes solvent regeneration. The membrane contactors will be equipped with a composite membrane with a dense layer plug that avoids the limitations associated with wetting the membrane.
The challenges are as follows :
- Design biobased solvents with low toxicity and good operability for use by non-specialists, with low environmental impact (volatility, product degradation, land use, etc.).
- Design an energy-efficient process with a limited energy footprint (quantity and quality of energy).
- Propose a modular design for the process, using intensified technologies such as hollow fibre membrane modules or a rotating packed bed.
Planned duration 6.5 years – Planned budget €7.5M
Design of new solvents, new membranes for membrane contactors, modelling and experimentation of membrane contactors, ageing and degradation of separative media, modelling, experimentation and design of RPBs dedicated to CCS, integrated modular unit for CO₂ capture.
The TRL level of the project is governed by the TRL of the solvent. The project will start at a TRL 1.
The membrane and RPB technologies start at TRL 2 and the integrated process is expected to be taken to TRL 4 by the end of the project.
Expected results: 4 to 6 patents, 3 to 5 ecological solvents, at least two proofs of concept (membranes and RPB), process simulation tools, 8 PhD students, 4 postdocs (78 months), between 20 and 30 publications.
The commercialisation of the products should create business for players producing membranes and modules (e.g. Polymen), for technology integrators and licensors such as Axens or Arrol, as well as end users of CO₂ through the consumption of fossil fuels or as a result of their process (e.g. methanisation).
