This interactive training unit is designed to familiarize trainees with the basic principles of the distillation process. After completing this unit, trainees should be able to explain how changes in the state of matter relate to the distillation process and how these changes are affected by temperature and pressure. They should also be able to explain how a liquid mixture can be separated into lighter and heavier components by distillation, and be able to describe the basic operation of single-batch distillation systems, successive-batch distillation systems, and continuous distillation systems.

Principles of Distillation

·         Explain how changes in temperature and pressure affect the boiling point of a substance.

·         Define distillation.

·         Explain how changes in the state of matter relate to the distillation process.

·         Define: sensible heat, initial boiling point, boiling range, final boiling point, and latent heat.

·         Define: vapor pressure, external pressure, partial pressure, and relative volatility.

·         Explain the relationship between vapor pressure and the following: boiling point, temperature, and external pressure.

Distillation Processes

·         Explain how a liquid mixture can be separated into lighter and heavier components by distillation.

·         Describe the characteristics of liquid mixtures that make distillation possible.

·         Describe the basic operation of single-batch, successive-batch, and continuous distillation systems.
