However, the process design for production and separation of L1E is challenging due to its complex kinetics. This work provides a modified design by using a side draw to obtain high purity L1E from the 1st reactive distillation (RD) column in reactive part. Besides, several separation configurations recycling reactants are implemented to investigate the most economic process design. The final result shows that the heat duty saved as much as 22.3 % in the reactive part by using a side draw. Also, the pervaporation (PV) module in the separation part is more economical than extractive distillation (ED) in terms of total annual cost (TAC). ? 2018 Elsevier B.V. |
