Chemical engineering is some studies to make control chemical plants on an appropriate condition and to design a series of apparatuses (a reaction device or separation device) constituting a chemical process reasonably. In addition, separation and purification of the products obtained from a reactor is one of the most important operations in a chemical process. In this class, the separation principle, the basic design method and the basic operation of the separation technologies, distillation, liquid-liquid extraction, gas absorption, drying and humidity conditioning that are the representative separation technologies in the chemical process, particularly a petrochemistry process) are commented in this class.
Understanding of the separation technologies and learning how to design separation facilities

|✔ Specialist skills||Intercultural skills||Communication skills||✔ Critical thinking skills||✔ Practical and/or problem-solving skills|
At the beginning or the end of each class, solutions to exercise problems that were assigned during the previous or present class is reviewed. To prepare for class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.
|Course schedule||Required learning|
|Class 1||Estimation of gas-liquid equilibrium, single distillation and flash distillation||Understanding of estimation of gas-liquid equilibrium|
|Class 2||Distillation of binary system and its design method||Understanding of McCabe-Thiele method|
|Class 3||Liquid-liquid equilibrium and liquid-liquid extraction operation||Understanding of liquid-liquid equilibrium and extraction operation|
|Class 4||Solubility and gas absorption using a packed column||Understanding of Henry's law and the operation of a packed column gas absorber|
|Class 5||Overall mass transfer coefficient and design method of a packed column gas absorber||Understanding of film theory, mass transfer coefficient and the design method of a packed column gas absorber|
|Class 6||Basics of humidity conditioning||Understanding of psychrometric chart|
|Class 7||Basics of drying||Understanding of drying rate curve|
|Class 8||Final examination|
To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
Distribution of the documents prepared by the instructor
Some documents are distributed at the time of a lecture start as needed and the class is performed a commentary using Power point. The Power point file to use in a lecture discloses it beforehand through OCW.
We evaluate an understanding degree of the students by the results of practice in the classes and the final exam.
Students must have successfully completed both Chemical Process Stoichiometry and Transport Phenomena III (Mass) or have equivalent knowledge.
