Distillation in the pharmaceutical industry SpringerLink

Though many separation techniques exist, the one most often used is distillation. Distillation is simple, has few moving parts, is well understood, can be simulated readily, and often has a low capital cost. On the negative side is the high operating cost associated with high energy requirements to vaporize and condense.
