Distillation is an important technique of separation that is used  in almost  every Chemical Industry. So the knowledge of distillation is very important for every Chemical engineer . In this course, we will study briefly about distillation: Principles, types of columns, Column Internals, Mass Balance, problems faced during operation and basic troubleshooting etc.

This lecture discuss about the basics of distillation, the VLE Relations and the Relative Volatility.

Introduction to Distillation

Briefly discusses various methods of distillation, namely, flash, differential, azeotropic, steam, and continuous distillation.

Distillation Methods

In this lesson we have discussed the a Continuous Distillation Column, total and component Mass Balance, McCabe Thiele Assumptions, and Operating Line equations.

Mass balance and Operating Line Equations

It discusses plotting of number of stages by McCabe Thiele Method, location of feed tray, q-line equation and effect of feed conditions.

McCabe Thiele Method

In this lesson we have discussed about the minimum, maximum and optimum  reflux ratios.

Choice of Reflux Ratio

In this lesson tray efficiencies, namely, overall, murphee, and point efficiencies are discussed.

Tray Efficiencies

In this lesson, we have discussed about Fenske Equation which determines the minimum number of stages required in a distillation column.

Fenske Equation

In this lesson we have discussed about sieve trays, valve trays and bubble cap trays.

Types of Tray Columns

In this lesson we have briefly discussed about packed towers ; random and structured packings.

Packed columns

In this lecture we have discussed 3 factors that affect the working of a Distillation Column ; namely number of trays, location of feed tray and weather conditions.

Parameters Affecting Performance of a Distillation Column

In this lesson we have discussed about some more factors that affect the performance of a Distillation Column namely ; feed conditions, reflux conditions, and state of trays and packings.

Factors Affecting the Performance of a Distillation Column Part 2

In this lesson we have discussed about the various adverse vapor flow conditions like foaming, entrainment, weeping /dumping, and flooding.

Factors Affecting the Performance of a Distillation Column Part 3

In this lesson we have discussed the effects of Column diameter, overloading and over-fractionation in a distillation column.

Parameters Affecting the Performance of a Distillation Column

In this lesson we have discussed about puking, pump around, and surging of liquid in a distillation column.

Other Important Phenomenons in a Distillation Column

In this lesson we have discussed the types of reboilers , namely, kettle reboilers, thermosyphon reboilers, fired reboilers and forced circulation reboilers.

Types of Reboilers
