GASP research interests are mainly about fluid-fluid separations. Applications are in the oil&gas field, in the process industry and in carbon dioxide capture.

In all our research areas there is a close synergy among theory, modeling and experiments and our activities span all the relevant aspects of a separation process from principles – we have developed a good expertise on thermodynamic equilibria –  to the integrated process.


Our current research topics are about:


Thermodynamic modeling

  • analysis of vapor-liquid, vapor-liquid-liquid and solid-vapor-liquid equilibria;
  • development of packages for the thermodynamic characterization of particular systems (acidic gas, cryogenic systems);
  • hydrates formation prediction.

  • separations in oil&gas plants (C2+ removal, dehydration, …) and in process industry;
  • hydrocracking of Fischer-Tropsch waxes;
  • energy saving oriented modeling.
