The Technology & Technical Support Business Division (TTS) is hiring:

Internship - Process Engineering - CO2 Balance and OPEX Estimation

Location : Rueil-Malmaison

Context
Our Technology and Technical Support (T&TS) Business Division (BD) is responsible for supporting sales by
providing advanced technologies and catalysts through technical proposals, as well as assistance services for
catalyst loading and post-start-up unit monitoring across all Axens business areas (Oil & Biomass conversion,
Petrochemicals production & purification, Gas and Water Treatment, CO2 capture).
More specifically, the objective of the "Responsible Hydro processing" Product Line is to deliver sustainable, highperformance solutions for producing clean fuels and petrochemical intermediates from petroleum (particularly
Diesel and VGO cuts) or any other carbon source, including bio-based feedstocks and those derived from the
circular economy. Our product line is distinctive in its mastery of a broad portfolio of technology platforms capable
of processing the alternative feedstocks that refineries of the future will use to support the energy transition.

Tasks and activities
We are offering an internship focused on developing a tool to estimate utility consumption for our hydrotreating units
in operation, based on operating data collected from our clients. The tool will enable us to perform OPEX
calculations and CO₂ balance assessments, thereby supporting our clients in optimizing their operations. It will also
serve as a client-facing benchmarking solution, with the goal of identifying and proposing actionable ways to
improve energy performance.
Key project steps
- Parameter identification and experimental design: Identify the key parameters influencing utility
consumption across the different pieces of equipment and define a design-of-experiments approach.
- Simulation-based database development: Build a simulation-generated database that will be used to
develop statistical models.
- Digital implementation and visualization: Deploy the tool on our digital platform and create dashboards
for visualization and value delivery.

Position to be filled from 1/1/2027
