| Abstract | At present, the chemical processes have very complex owsheet with recycle stream, energy integration and different unit operations. Generally, a chemical plant consists of reaction sections and separation section. Both sections need to control system for the safety and economical in plant. This work presents the new heat exchanger 3 networks and 3 alternatives of control structure for acetone plant. Heat exchanger network (HEN) are modified in traditional process for energy saving. The plantwide control structures are designed by using the disturbance load propagation method (Wongsri, M., 1990) and heat pathway heuristics (Wongsri, M. and Hermawan Y.D., 2005) to achieve dynamic maximum energy recovery (DMER). In this work, HYSYS is evaluated performances of the heat exchanger networks and control structures. The result shows that alternative 2 can save energy 81.49% and CS2 is the best control structure for controlling disturbance |
