Difference Between Unit Operation And Unit Process

Unit operation

1.Unit operation involve a physical change of reactant into desired products    

                                         

2. It is primary process

3. In unit operation usually a mechanical equipment is required

                            

4. It is reversible process

             

5. Example: separation, crystallization, evaporation, filtration

                           

                                         

Unit process-:

1. Unit process involve a chemical changes of reactant into desired product

                                       

2. It is secondary process

3. In unit process heat, temperature, pressure, catalyst required along with mechanical equipment

                                       

4. It is Irreversible process

                

                          

5. Example: Any reaction such as oxidation, reduction,hydrogenation
