Simulation of a new regeneration process of solvents with ionic liquid by short-path distillation

► Simulation of a new regeneration process for solvents with ionic liquid by short-path distillation. ► Estimation of process parameter in regeneration of IL-dodecane solvent loaded with butyric acid. ► Yield of butyric acid is strongly influenced by residual content of BA in recycled dodecane. ► Energy consumption in distillation is influenced by dodecane content in the solvent.
