La thèse vise à développer un jumeau numérique d’un séparateur liquide-inclusions (polluants) par flottation dans l’objectif d’optimiser les procédés de flottation industriels pour répondre aux enjeux liés au traitement des eaux, qui apparaît comme un besoin primordial dans un contexte de changement climatique.

Near Infrared spectroscopy (NIR) combined with chemometrics has been used for years in various fields to predict properties, quantify species, classify samples, etc. At IFPEN, this approach is daily used in the laboratory and on-line on pilot plant units to predict properties of interest of petroleum cuts.

In CCS (CO2 capture and storage) CO2 storage in depleted petroleum reservoirs is envisaged. Hydrates CO2 crystals formation may lead  to important injectivity losses and even to a complete plugging of the injector well and hydrates risk is identified as crucial for the CO2 storage operation.

IFPEN is a leading actor in the development of hydrocracking processes ranging from the hydro-treatment of petroleum products to the production of biofuels. In order to properly scale-up the catalytic sections of these processes robust and evaluated simulation tools are needed and developed by IFPEN.

The decarbonization of the electricity mix is based on the development of intermittent renewable energies and the decentralization of the power generation means.

The electric transmission system is a key element of future mobility. It is desirable to reduce the footprint, increase the efficiency and power density of the entire electric traction system.

The recycling of plastics is a major issue in the energy transition. These materials are widely used in many fields: packaging, automotive, household appliances, construction, agriculture, thus generating a significant amount of waste. Today, recycling is mainly done through mechanical recycling processes.

Adipic acid is considered as the most important dicarboxylic acid of global market and it has been included among the 50 most used chemicals in the US. Its main application concerns the synthesis of polyamides-6,6, also called “Nylon”, which demand about 50% of the global production of adipic acid.

As part of the National Low Carbon Strategy, reflecting France's ambition to achieve carbon neutrality by 2050, the decarbonisation of industry must result in a reduction in greenhouse gas emissions of 35% and 81% respectively by 2030 and 2050 compared with 2015. One of the solutions envisioned is the development of decarbonized hydrogen.

IFPEN aims to become a key player in the triple energy, ecological and digital transition by offering differentiating technological solutions in response to the societal and industrial challenges of energy and climate.

Fine particles are among the main contributor to poor air quality. They are particularly monitored as 97% of the European population living in urban areas was exposed in 2021 to particle concentrations above the WHO guideline of 5 µg/m3.
