Energy integration in real and large process is considered important because a large amount of energy can be conserved with the use of energy integration. Hence, it is a common practice to install Feed- Effluent Heat Exchangers (FEHEs) around reactors and distillation columns to recover energy. The bypass control for process to process exchanger is common used for heat recovery within a process and it is essential to design a control strategy for process associate with energy integration. However, the control performance will be degraded in real applications as the existence of external disturbances. Thus, the dynamic responses of the bypass location and control point under disturbances should be considered. In this work, Hydrodealkylation (HDA) process of toluene to benzene simulated by HYSYS simulator is chosen as a case study. The four alternatives of the bypass location and control point are introduced to the FEHE.
