REACTION ENGINEERING - 2023/4

Module Overview

The heart of any chemical or biochemical processes is often said to be the reactor. A comprehensive understanding of reactors’ performances is a pre-requisite for the process design. This Reaction Engineering module builds on the reaction kinetic knowledge from level 1 and applies it to the design of homogeneous chemical reactors and bio-reactors. The module creates connections to real-world chemical process design examples, and covers some important aspects of chemical engineering design called green chemistry and sustainability of chemical industry.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate 

the full range of learning outcomes though the balanced mixture of lecture and tutorial/problem classes coupled with the carefully grades tutorial problems which reflect current industrial practice.

Students who successfully complete this module will be able to be equipped with industrial life beyond academia as well as to develop teamwork and communication skills, critical thinking, problem-solving and analytical skills.

Thus, the summative assessment for this module consists of:

• Class Test – 20% (LO1, LO2, LO3, LO4)


• Examination – 80%, 2 hours (LO1, LO2, LO3, LO4, LO5, LO6)

• Weekly verbal feedback will be given during tutorial classes.


• Written feedback on the Class Test

Module aims

• Allow students to develop knowledge, skills, and capabilities in diverse areas focusing on Chemical Engineering
• Enable students to develop a comprehensive understanding of the methodology of linking chemical kinetics with material and energy conservation in the design of idealized homogeneous chemical reactors and bio-reactors, operating either in batch or continuous mode, and under either isothermal or non-isothermal conditions.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

• Carefully cover in lectures the necessary fundamental material and analytical techniques, and demonstrate concepts with appropriate (and where possible practical) examples


• Allow students adequate time to practice the techniques using a large number of carefully selected tutorial problems.

• Lectures                               


• Tutorial/Quiz/Problem Classes        


• Independent and guided learning               

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.

Other information

The School of Chemistry and Chemical Engineering is committed to developing graduates with strengths in Employability, Digital Capabilities, Global and Cultural Capabilities, Sustainability, and Resourcefulness and Resilience. This module is designed to allow students to develop knowledge, skills, and capabilities in the following areas

Employability: This module uses some industrial chemical process design examples during the lecture to illustrate concepts in design of chemical reactors and bioreactors, helping students to be equipped with industrial life beyond academia. Students are also given some open-ended reaction engineering quizzes/problems to solve in a team during tutorial/lecture hours, which could help them to develop teamwork and communication skills as well as critical thinking, problem-solving and analytical skills.

Digital Capabilities: With hands on practice on POLYMATH software during tutorial/lecture hours, students enhance their understanding of fundamental elements in chemical reaction engineering. The POLYMATH software would provide a digital platform to explore the real-world chemical reaction engineering examples and ask “what-if” questions, developing understanding that can be applied to industrial chemistry with real reactors and reactions, and an even broader range of applications.

Global and Cultural Capabilities: Students would need to work on some open-ended reaction engineering quizzes/problems related to reactor and chemical plant design that borders and overlaps with other engineering disciplines including mechanical, electrical, and civil engineering as well as business studies and entrepreneurship. This could help students to excel in critical problem solving, work in multidisciplinary teams and develop the skills which enable them to work in diverse high-level careers.

Sustainability: Achieving sustainable processes, that allow us at present to fully meet our needs without impairing the ability of future generations to do so, is an important goal for current and future engineers. In production of new materials, chemicals, and pharmaceuticals sustainable processes certainly require the most efficient use of raw materials and energy, preferably from renewable sources, and prevention of generation and release of toxic materials. Advancing the state of the art of chemical reaction engineering is the key element needed for development of such environmentally friendly and sustainable chemical processes. This module will provide multiple examples related to the improvement of chemical reaction processes via new reactor designs that help students to gain knowledge on the green and sustainable chemical engineering, which involves making all chemical processes more environmentally friendly and sustainable.

Resourcefulness and Resilience:  Students are allowed to choose their groupmates to finish open-ended reaction engineering quizzes/problems during tutorial/lecture hours. This activity would help students to develop critical thinking, problem-solving and analytical skills as well as learn how to work with others to deliver the engineering solutions. Support by teaching staff is offered to facilitate groupwork discussions and team building.
