What is Chemical Engineering?

The basis of this course is the field of discipline called chemical engineering. What is chemical engineering like? You must certainly know that all materials are in one of three states: gas, liquid, or solid. Chemical engineering has been developing and improving manufacturing processes where gases, liquids and solids are mixed, reacted, and separated.

Structure of Chemical Engineering

The field of discipline called chemical engineering is comprised of physical chemistry, reaction engineering, biochemical engineering, mass transfer engineering, thermal engineering, fluid engineering, equipment design engineering, and process system engineering. When you handle materials, first you have to know their characteristics. Physical chemistry is the study of the characteristics of materials. It is easy to mix, react, or separate materials in a test tube or flask, but it becomes very difficult under high temperature or pressure, or in large equipment. Reaction engineering is the study of reactions within industrial equipment, and biochemical engineering is the study of production of useful materials with the help of organism ability. Finally, mass transfer engineering is the study of the mixture and separation of materials.

It is necessary to heat, cool, and transport materials for the purposes of mixture, separation and reaction. The study of heat energy is called thermal engineering, while the study of the motion of materials is called fluid engineering.

Additionally, the actual manufacturing of products requires technologies to design the shape and size of the equipment and the material for mixture, separation and reaction (a science known as equipment design engineering), and technologies to manufacture products in the factory (a science known as process system engineering).

Development of Chemical Engineering

ased on the components described above, Chemical Engineering has been developing new materials such as biochemical materials, electronic materials, new catalysts, etc., and their production technologies and highly advanced separation technologies. Further, its coverage now is going to become wider from designing of equipment and advancing of control technologies to the development of computer science including artificial intelligence and simulation technologies. For example, research and development on biotechnology and bioengineering including solutions of energy and environment problems and artificial organs by considering the earth or biochemical body as a factory where materials are mixed, reacted and separated. As described above, Chemical Engineering has become a key technology for technological innovation and problem solving.

In the Chemical Engineering course, seniors with a basis in chemical engineering have already achieved much success in research regarding these fields. We are expecting more developments to be made in future eras.
