Distillation is the most widespread separation method in history.1 Despite its simplicity and flexibility, distillation remains a very energy-inefficient process. Novel distillation concepts based on process intensification (PI) principles can deliver major advantages in terms of significantly lower energy use and reduced capital costs while improving ecological efficiency. The PI concept has been around since the mid-20th century, but has received more attention in the last two decades. The objective of PI is to design substantially smaller plants while improving their operational safety, environmental performance and energy efficiency. The Rapid Advancement in Process Intensification Depl
