Distillation Column has been widely used in industrial area where chemical processing and waste water treatment plays a significant role. It is also used nowadays in solvent recovery processes.

1. Design of an Ideal Distillation
Column

2. Distillation process used in solvent
recovery is divided into two major
categories
 Batch Distillation Process
 Continuous Distillation Process

3. Batch Distillation process
 As the name suggests it is carried out in
batches
 It is useful for low capacity and high purity
chemicals
 Based upon the difference in the volatility of
the component present in the sample mixture
 It hold some advantageous feature over the
normal distillation process such as flexible
process, separates several component in one
go using one column, economical process,

4. Design of conventional Batch
Distillation Column

5. Working of Batch Distillation
Design
 In Batch Processing once the sample is feed
into the column it undergo the evaporation,
condensation and again the evaporation to
produce the highly pure form of the
components
 Qc is condenser through which the component
is collected

6. Continuous Distillation
Column
 Similarly like batch distillation column,
Continuous distillation column is named after
the process involved in the distillation of the
component
 It involves continuous addition of the sampe
required to be separated into its component
 The component separated from the sample is
continuously removed for the reaction stream

7. Continuous Distillation Column
Design

8. Working of Continuous Distillation
Column
 Continuos Distillation involves continuous feed
of the sample in the column which is
processed and continuously condense the
components separated from the sample
mixture
 Distillation Column has been widely used in
industrial area where chemical processing and
waste water treatment plays a significant role.
It is also used nowadays in solvent recovery
processes.
