published on , updated on

The Chemistry and Process Engineering Team is equipped with a number of pilot-scale units including absorption, adsorption, biological processes, oxidization and membrane processes.

Absorption processes (with or without chemical reaction)

  • One pilot-scale packed bed column for gas scrubbing (gas flowrate 10 m3/h)
  • One pilot-scale gas scrubber with compact contactors (gas flowrate 50 m3/h)
  • One pilot-scale spraying gas scrubber (gas flowrate 25 m3/h)
  • One gas-liquid diphasic stirred tank for reaction kinetics studies (notably in the case of ozonation process) (gas flowrate 1.5 m3/h)

Adsorption processes

  • Lab-scale equipment for kinetic, isotherm and competition studies in both gas and liquid phases
  • Gas phase activated carbon fibre cloths pilot-scale unit with controlled temperature for thermal regeneration (gas flowrate 10-30 m3/ h)
  • Liquid phase adsorption/electrodesorption pilot scale unit using activated carbon fibre cloths with on-line pollutant spiking and automated sampling.
  • Granular activated carbon fix-bed columns with multiple sampling points.
  • Equipment for synthetic gas generation by COV volatilization in gaseous matrix (air, biogas)


  • Two lab-scale fermentors
