COSMO-RS as a computational prediction tool

for thermodynamic behaviour of fluid mixture in separation processes


Background: COSMO-RS (Conductor-like Screening Model for Real Solvent) has attracted much attention due to its ability to describe thermodynamic properties and behaviour of solvents such as ionic liquids. It is a model which combines two methods, i.e. (i) quantum chemical considerations in the form of a conductor-like-screening tool, and (ii) statistical thermodynamics. The combination enables the determination and prediction of thermodynamic properties without requiring experimental data. It is a reliable tool for solvent screening and qualitative prediction of thermodynamic behaviour of fluid mixture.


Objective and Outline: The Workshop is to demonstrate the general use of COSMO-RS programme as a computational prediction tool. It will cover the following topics: (a) Theory and background of quantum chemical methods, (b) Introduction to COSMO-RS and its principles, and (c) Applications of COSMO-RS. Participants will be exposed to the relevant theories and will be involved in practical learning sessions.


Learning Outcomes: After attending this Workshop, participants should be able to:

  • Perform molecular geometry optimization and create .cosmo files for use in COSMOtherm.
  • Utilize COSMOtherm for specific applications of interest.
  • Demonstrate the importance of computational tools for prediction of thermophysical and thermodynamic properties of fluid mixtures.

Workshop tutors:

  1. Prof Ir Dr Mohd Ali Hashim

Prof Mohd Ali is the Head of Universiti Malaya Centre for Ionic Liquids, where multidisciplinary research teams are involved. His research interests are in the synthesis of ionic liquids and deep eutectic solvents, a class of green chemicals that can replace the toxic and harmful industrial solvents. Their applications are wide-ranging and include processes such as desulphurization, acid gas capture, biodiesel production, redox-flow batteries, catalysis, liquid membrane and wastewater treatment.
