Class Objectives
/Class Outline To learn the knowledge and get the ability necessary to plan and design chemical processes.
The actual contents are as follows.
1) Understanding of the background and properties of the target chemical plant, selection of the chemical processes
2) Acquisition and estimation of necessary data
3) Decision of the reaction and separation methods
4) Analyses of mass and heat balances of process components
5) Basic design of the chemical equipments
6) Understanding of the process flow and the function of process components
7) Analyses of mass and heat balances of the chemical plant
8) Optimization of the chemical process based on the economic efficiency and safety

Class Schedule Lessons 1: Estimation of physical properties of materials in the ethylene oxide process
Lessons 2: Vapor-liquid equilibrium activity estimation using UNIFAC (Section 2.5.8) and solubility equilibrium (Section 2.5.9)
Lessons 3: Material balance and product cost estimation for a 100% separation efficiency process (Sections 3.1 and 3.2)
Lessons 4: Material balance of the process considering separation efficiency (Section 3.3)
Lesson 5: Isothermal reactor design (Section 4.1)
Lesson 6: Non-isothermal reactor design (adiabatic) (Section 4.2)
Lessons 7: Non-isothermal reactor design (constant tube wall temperature) (Section 4.3)
Lessons 8: Non-isothermal reactor design (heat exchange type) (Section 4.4)
Lessons 9: Distillation column material balance (Exercise 5.1)
Lessons 10: Mass balance of absorber and stripper towers (Exercises 5.2 and 5.3)
Lesson 11: Recycling mass balance in separation processes (Exercise 5.4)
