Reactive Distillation is a very promising alternative to conventional reaction-distillation flow schemes. In a reactive distillation column the chemical conversion and the distillative separation of the product mixture are carried out simultaneously in one single unit. As a consequence of this integration process efficiency can be increased and investment and operational costs can be reduced. Highly renowned international experts from both industry and academia review the state-of-the-art and the future directions in application, design, analysis and control of reactive distillation processes.
