Chemical process is composed of reaction and separation units, in which chemical reaction unit is one of the most important units. In order to produce an objective product efficiently, appropriate selection and strict operation of reactors are an important issue. This course provides a method to design batch- and continuous-type reactors used in gas- or liquid-phase homogeneous reaction.
First, approximate derivation methods for chemical reaction rate are introduced to describe several chemical reactions such as radical, cracking, polymerization and enzyme reactions. Basic design methods for the reactors are explained, based on the mass-balance equation including the chemical reaction rate. Finally, these basic knowledge is expanded to the designs for continuous-tanks reactor, multi-tubular reactor,semi-batch reactor and reactor with recycle system. Finally, the effects of reaction temperature, volume of reactor and reaction times on the conversion and product yield are taught.
By the end of this course, students will be able to:
1) derive reaction rate equations
2) derive mass-balance equations for reactor design
3) design several types of reactors and to understand these characteristics
4) understand the reactor design's method for multiple reactions
5) understand the changes in mass, conversion and yield with time

✔ Specialist skills | Intercultural skills | Communication skills | Critical thinking skills | ✔ Practical and/or problem-solving skills |
Required learning should be completed outside of the classroom for preparation and review purpose.
In every class, a summary of the previous lecture is given. Towards the end of class, students are given exercise problems related to what is taught on that day to solve.
