Reactive Distillation in DWSIM

Learning Objective 

• How to setup chemical reaction kinetics in distillation column. 

• How to specify reaction chamber inside distillation column. 

• How to recover unreacted reactant and recycle it. 

• How to use pump and valve unit operations

 

Basic Information 

It integrates chemical reaction and distillation in a single apparatus. (reversible,liquid phase reactions)

 Removing one or more of the products is one of the principles behind.

 

reactive distillation:

>reduced capital investment 

>significant energy savings 

>surpass equilibrium limitations 

>simplify complex processes

 >Increase product selectivity

>improve separation efficiency.

Interaction between set points and process variables


It is an extension of steady-state whereby time-dependence

 

is built into the models i.e. accumulation of mass and energy.

 

Control of real processes are possible.

 

The calculations are more complex and time consuming.
