Course description and aims

The life of a chemical plant is more than 50 years from construction to the disposal, and the management through the life cycle is necessary. Therefore, it becomes important to design process structure and process operation logically in the conceptual and preliminary process design phases. To realize such logical process design, modularization of the objective process becomes the key technology. In this cause, students learn methodology to modularize process and operation using a simple commercial process example, and acquire the basic ability to engineering design of chemical processes

Student learning outcomes

At the end of this course, students will be able to:
1) Perform the operational design in the conceptual design stage of the chemical process, 2) Acquire the ability to modularize operation and process, and to integrate them for the operational design.
In this lecture, the process design at the conceptual design stage will be advanced using the process simulator, taking a commercialized real process as an example. The key factor is how to integrate the process module and the operational module, and the combination of modularization technology will be acquired.

Course schedule/Required learning

  Course schedule Required learning
Class 1 Conceptual Process Design Overview Understanding the conceptual process design process in the overall process design process.
Class 2 Process Schematic Design and Process Design Variables Identifying the feasible operating regions of each unit, designing the process scheme to satisfy the identified operating regions, and specifying the process design variables for the designed process scheme.
Class 3 Reaction System Design under Consideration of Critical Factors Identify the factors that determine the reaction system performance, designing the reactor system, and determining the process design basis.
Class 4 Distillation Process Design The design of the distillation process initially sets the quality target and then designs each distillation column that constitutes the distillation process. In the case of a simple column with one input and two outputs, the operating pressure, the feed point, and the total number of stages become design variables, with the quality requirement specifications for the number of outputs as constraints.
Class 5 Heat Exchanger Network Design Calculating energy recovery targets using Composite Curve and Problem Table.
Class 6 Heat Exchanger Network Design Designing the heat exchanger network by Pinch Design Method.
Class 7 Process simulation practice 1 Conduct conceptual design of reaction unit operation of DME process using process simulator.
Class 8 Process simulation practice 2 Conduct conceptual design of DME distillation tower and Me-OH distillation tower of DME process using process simulator
