LGC  Laboratory

The Laboratoire de Génie Chimique (LGC), UMR 5503, which employs about 300 people, is a CNRS research unit operated jointly by the CNRS, the Institut National Polytechnique of Toulouse (INPT) and the University - Paul Sabatier (UPS) of Toulouse. The research staff of the LGC is accommodated in four different buildings located in INP-ENSIACET, INP-ENSAT, UPS- Faculty of Engineering Science (FSI) and Faculty of Pharmaceutical Science (FSP).


The research is particularly active in the design of hybrid processes, microprocesses, processes for the production of advanced materials including micro or nanoparticles, nanostructured objects, the production of carbon-free energy, the treatment of water and waste water, and healthcare engineering. The Laboratory scientific approaches are both experimental and computational (modelling, simulation, optimization, design). The LGC has a series of pilot plants covering the laboratory scale up to the demonstrators in which real industrial conditions can be approached. The laboratory also develops specific experiments at the nano- and micro-scales generating fundamental data. It also benefits from a large pool of instruments for characterization and analysis (scanning electron microscopy, characterization of particles, chromatography, ICP, etc.) gathered in the Service for Analysis and Processes (SAP) on the INP-ENSIACET Campus or in the Measurements and Analysis Service on the UPS-FSI campus. In addition to these experimental techniques specific means of calculation and commercial or internally developed software are available. The laboratory also trains through research , a large number of students (master, doctorate, post-doctorate) and maintains a regular partnership with socioeconomic partners for the transfer of new scientific knowledge and innovative technologies through training or research contracts.

Due to its human potential, the LGC brings together the largest number of researchers in the field of Chemical Engineering in the whole country with 160 permanent employees and an equivalent number of PhD students and post-docs.

Research departments

The LGC is composed of six scientific departments which are supported by technical and analytical services.

Interface and Partice Interaction Engineering (GIMD)

  • Study of the physical or physico-chemical interactions playing a role in solid-liquid, liquid-liquid or gas-liquid interfaces in dispersed phase or membrane processes . The generation and behaviour of interfaces are studied by connecting mechanisms at a very small scale with the macroscopic properties of the medium and/or the process.

Electrochemical Processes (PE)

  • Development of methods and electrochemical tools for the design, sizing and control of processes: phenomena and chemical reactions in real media using multi-scale experimental and numerical approaches by confronting the laws and concepts of physico-chemistry to real media..

Innovative Multiphase Reactor Engineering (IRPI)

  • Development of new multiphase reactors with or without chemical reactions. Skills in catalytic reactor engineering, advanced oxidation, fluidization, CVD and activation are used for applications in environmental decontamination, energy and the development of new materials.

Bioprocesses and Microbial Systems (BioSyM)

  • Understanding and driving microbial activity in agronomy and food industry processes, energy production, as well as environmental and healthcare sectors. Researchers from BioSyM bring together expertise in process engineering, industrial microbiology, physiology of microorganisms, bio-electrochemistry and toxicology.

Science and Technology of Intensified Processes (STPI)

  • Design, scale-up, operation and security of intensified processes involving multifunctional instruments, green solvents, energy efficiency and biosourced carbon. Research focuses on industrial scale processes, associating equipment design and technology, as well as final product specifications.

Process System Engineering (PSE)

  • Development of a systemic approach of innovative engineering and optimal operation of sustainable processes, from the molecule to the enterprise scale: generic tools for modelling, simulation, multi-objective optimization, to design interconnected equipment in a production unit.

The research finds applications in the environment, energy, biology and health.
The laboratory is involved in several networks and federations such as:
Thematic Network of Advanced Research ("Sciences et Technologies pour l’Aéronautique et l’Espace")
Water Competitiveness cluster
FERMAT Federation ("Fluids, Energy, Reactions, Materials and Transfers")
Rio Tinto Alcan-CNRS , a common team for molten-salt processes.

Research-driven clusters:

  • AMC2 (Multi-physical Approaches for Colloids ),
  • Bio-systems for engineering
