Welcome
2
Tatyasaheb Kore Institute Of Engineering
Technology

• Seminar on,
• Reactive Distillation
• Presented By,
• Mr. Nikhil parit
• Guide,
• Prof. S. T. Patil

3
Distillation

• Separation Technique
• Heat Energy
• Depend on volatility
• Maximum purity

4
What is reactive distillation???

• reaction and distillation in one column
• Doesnt Required any separate column after
  reaction
• RD saves Energy and material

5
Importants of RD
6
Suitability of RD

• Depends upon,
• Volatility of reactant
• Volatility of product
• Reaction temperature
• Distillation temperature

7
Conventional process
8
Reactive Distillation
9
Applicable processes

• Acetylation
• Aldol condensation
• Alkylation
• Amination
• Dehydration

10
Applicable processes

• Etherification
• Esterification
• Hydrolysis
• Transesterification
• Isomerisation

11
Benefit of RD

• Save Energy And Material
• Increases Speed
• Reduces Equipment
• Less Waste Of Reactant
• Lower Byproduct Forms

12
Benefits of RD

• improved product quality
• Improved selectivity
• Better heat control
• effective utilization of heat
• avoidance of azeotropes

13
Constraints of RD

• problem in endothermic reaction
• VLE temp equivalent to reaction
• temp
• thermal stability of catalyst
• chemical reaction in wet catalyst

14
Esterification-

• Eg. Methyl acetate
• HOAc MeOH MeOAc H2O
• conventional process
• large excess of reactor in
• series
• nine distillation column

15
Esterification

• conventional process
• separation of acetic acid from
• water is much difficult
• complicated process

16
Conventional process
17
Esterification in RD

• 99.9 conversion
• pure methyl acetate
• four times more efficient than
• conventional process
• very less capital cost operating cost

18
Methyl acetate using RD
19
conclusion

• no. of specific advantages over
• conventional process
• no any affects on environment
• low capital and operating cost
• maximum replacement to conventional
