Welcome to the Chemical Engineering Laboratory (LGC)

Our lab unit, is a National Center for Scientific Research (Centre National de la Recherche Scientifique CNRS ) laboratory, operated jointly by the CNRS, the University Toulouse 3 – Paul Sabatier (UPS) and the Institut national Polytechnique (INP) of Toulouse. 300 people work at the LGC.

LGC’s mission is to produce knowledge in the field of Chemical Engineering by focussing on industrial and societal constraints and issues while participating in the international competition of new knowledge creation.

Develop new knowledge, invent breakthrough technologies


Research conducted at the LGC aims

at designing, operating, optimising and scaling-up innovative processes for the process industries

The scientific approach

integrates and associates aspects related to equipment technology, the final product, as well as the global process. Current and future industrial demands for complex multi-phase multi-component products, tight product specifications and sustainable conditions require the development of diverse and innovative processes. At the LGC, new approaches are explored to better integrate specific operations at multiple scales, ranging from the molecular or particulate scale to the scale of the entire global process.


Research based on thermodynamics, as well as physical, chemical, electrochemical and biochemical kinetics enrich recent advances in phenomenological modelling, computational fluid dynamics, process simulation and instrumentation.

Key Societal Challenges

The LGC pursues its overall objective of developing research which can contribute solutions to societal challenges
