| Abstract | The energy integration causes to the interactions and may make the process more difficult to control. Therefore, in order to achieve maximum energy recovery and keep target temperatures at their desirable value, the control structures of energy exchanger networks are important. This work presents the new heat exchanger 3 networks and 4 alternatives of control structure for the hydrodealkylation of toluene (HDA) process with energy integration schemes alternative 6 are simulated using Luyben’s heuristics method. Various heat pathways throughout the network designed using Wongsri’s disturbance propagation. The main objective is to use plantwide control strategies to develop the new control structures for the hydrodealkylation process with energy integration schemes that are designed to achieve the control objective and reduce the cost of production. In this work, the performance of the heat exchanger network and their control structures are evaluated via simulation using HYSYS. |
