How will you CONTRIBUTE and GROW?


 

Internship Context


At Air Liquide, we are at the forefront of the energy transition, continuously developing innovative Carbon Capture technologies to meet global climate goals. A key component of our capture portfolio is the CryocapTM system developed by the engineering department.

As we scale and optimize these technologies, it is essential to deeply understand the chemical behaviors and trace compounds within our systems.

Specifically, managing and understanding phenomena such as NO2 hydrolysis is critical to ensuring the efficiency, safety, and reliability of our CO2 capture processes across different scales of operation.

Having a robust understanding of the behaviour of the different impurities is essential to explore the data from current R&D pilots and thus enable the design of future units.


Missions and Responsibilities


Your mission in this internship, as a part of the team Primary Production Technology at AL R&D will be to study the impact of NOx reactions through some bricks in the CryocapTM FG product.

By analyzing data from literature/pilots and comparing it with experimental outcomes, you will play a key role in validating our models and ensuring the safe and efficient scale-up of our carbon capture technologies.



The main missions entrusted to you will be:

  • Summarize the evolution of the different NOx reaction mechanism.
  • Study the updated mechanisms and understand the impact of the reactions within the CryocapTM FG CO2 capture process. 
  • Analyze and compare experimental results obtained from a pilot plant.
  • Evaluate and ensure the representativity of the model.
