  1. 1. Subject: PHARMACEUTICAL ENGINEERING-Theory SIMPLE DISTILLATION PREPARED BY: KASHISH WILSON ASSISTANT PROFESSOR, MM COLLLEGE OF PHARMACY, MM(DU), MULLANA , AMBALA
  2. 2. Contents:  Introduction & basic principles and methodology of 1. Simple distillation 2. Flash distillation 3. Factional distillation 4. Distillation under reduced pressure 5. Steam distillation 6. Molecular distillation
  3. 3. Introduction  Distillation is a process in which a liquid or vapour mixture of two or more substances is separated into its component fractions of desired purity, by the application and removal of heat.  Principle: Separation of components from a liquid mixture via distillation depends on the differences in boiling points of the individual components. And also depends on the vapour pressure characteristics of liquid mixtures.
  4. 4. Simple Distillation  In Simple distillation the only one chain of vaporization and condensation takes place  Its only applicable if difference of boiling points is very large like 25- 35`C.  It is mostly use to separate volatile liquid from nonvolatile liquids.  Its difficult get pure substance only by simple distillation.  Distillation of seawater.
