Ionic Liquids and Hyperbranched Polymers – Promising New Classes of Selective Entrainers for Extractive Distillation

Ionic liquids (IL) and hyperbranched polymers (HyP) represent new classes of nonvolatile selective solvents. By measuring vapor-liquid equilibria (VLE) of azeotropic and close boiling systems in the presence of ionic liquids or hyperbranched polymers, separation factors are derived and the potential of using IL and HyP as entrainer for extractive distillation is discussed. Exemplarily, the supe...

Extractive distillation with ionic liquids as solvents : selection and conceptual process design

In this chapter, a solvent selection methodology for extractive distillation processes is applied to identify promising ionic liquid (IL) solvents for the following separation cases: methylcyclohexane/toluene, 1-hexene/n-hexane and ethanol/water. Thermodynamic and phase stability analysis are done in order to understand the strong interactions between the solutes and the ionic liquids (solvents...

Ionic Liquid Selection and Performance Evaluation for the Separation of Methylcyclohexane/toluene by Extractive Distillation

The effectiveness of an extractive distillation process relies on the choice of the extractive solvent. The conventional methodology to select solvents is based on Group Contribution Methods. Ionic liquids have shown several advantages over conventional solvents used in extractive distillation and liquid-liquid extraction processes. However, there is no existing methodology to select ILs as sol...

Application of Extractive Distillation for the Separation of Benzene and Cyclohexane Mixture

Distillation is the most widely used separation technique in the chemical process industries. Not all liquid mixtures can be separated by ordinary fractional distillation, however. When the components to be separated of system have relative volatilities of close to 1.00 (i.e. close boiling mixture), separation becomes difficult and expensive because a large number of trays and a high reflux rat...

Comparison of Extractive and Pressure-Swing Batch Distillation for Acetone-Methanol Separation

The performance of extractive (BED) and pressure swing distillation (PSBD) for the separation of the mixture acetone(A)-methanol(B) forming a minimum azeotrope are compared. For the BED, where the solvent(S) is water, three different operational policies (basic, modified, controlled) are studied. For the PSBD the double column batch stripper (DCBS) is applied with and without heat integration (...
