STEAM DISTILLATION.pptx

  1. 1. Subject: PHARMACEUTICAL ENGINEERING-Theory STEAM DISTILLATION PREPARED BY: KASHISH WILSON ASSISTANT PROFESSOR, MM SCHOOL 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. Steam distillation  It is a process which is carried with the steam help for separating high boiling substances from non-volatile impurities.  It is helpful in separating immiscible liquids and volatile oil extraction such as clove and eucalyptus.  Volatile oil separated at low temperature in steam distillation  It is not suitable for immiscible liquid and water.
