In petrochemical and chemical processes, most separations involving mixtures with low relative volatilities as well as CO2 removal (recovery) are energy intensive. In bio-processes, the downstream separations are difficult because of product recovery from dilute solutions. Ionic liquids (ILs) based separation is emerging as a potentially sustainable and low energy consuming technology because of their non-volatility, good solubility and selectivity properties. That is, the removal of the solute and recovery of the IL-solvent requires very low energy and therefore, has low carbon foot-print. In this work, a method that combines group contribution based property prediction models for computer aided molecular (IL) design (CAMD) with process design is presented. Case studies involving CO2 capture from natural gas and separation of azeotropic mixtures are highlighted.
