Abstract

This chapter introduces the choice and usage of new separating agents (i.e. entrainers) in distillation processes. Such substances are preferentially used for the separation of narrow boiling and azeotropic mixtures using extractive distillation. The chapter focuses on ionic liquids and hyperbranched polymers. Because of their customizable properties, these two solvent classes can be used as entrainers for various separation problems. The regeneration of the entrainer is easy because the vapor pressures of both solvent classes are infinitely small. The thermodynamic choice of the best-suited entrainer can be done by solubility experiments (e.g. with headspace gas chromatography), by using a structure-interpolating method such as UNIFAC, or by an a priori predictive method (e.g. the Conductor-like Screening Model for Real Solvents) to calculate the solubility.
