Separation Processes Laboratory
spl.ethz.ch

Our mission is to develop efficient, safe, and sustainable processes for high quality products and environmentally responsible systems. To educate in the science and engineering of economically optimized and environmentally beneficial separation processes by conducting cutting edge research.

SPL research deals with adsorption-​based separations and chromatography, and with crystallization processes. Applications are in the purification of biopharmaceuticals and in carbon dioxide capture and storage systems.

  • Crystallization and precipitation
  • Adsorption and chromatography
  • CO2 capture and storage

In all research areas there is a tight synergy among theory, modelling, and experiments and our activities span all the relevant aspects of a separation process from fundamentals to an integrated process.
Experimental research can be conducted in cutting edge facilities featuring automated lab-​pilot units for PSA/TSA processes, mineral carbonation, supercritical fluid assisted precipitation, SMB processes (with online controller). Characterization techniques are available for particle size and shape distributions, adsorption isotherms, as well as spectroscopic instruments for online process monitoring.
