Course description and aims

The chemical process consists of various types of unit operations in order to convert raw materials to products. In the first place of this course, bases of unit operations related to treatments, e.g., separation, reaction, of materials, e.g., raw materials, products are introduced. Secondly, the basic methods for designing a number of typical unit operations are studied.

Student learning outcomes

After studying this subject, the students should be able to carry out a basic design of typical unit operations which make up a chemical process.


Unit operation, Equipment design, Chemical process

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

Lectures with exercise problems to deepen understanding of the subject
