This course introduces students to key concepts of process design, including the detailed design of unit operations. The course builds on the topics covered in the 1st Professional year and begins to explores how unit operations can interact to shift the overall optimal operating conditions away from, say, the conditions that optimise a reactor alone. The course also extends the process safety concepts introduced in ENCH295 to cover more quantitative analysis techniques and provides an introduction to materials engineering for chemical engineers.

An introduction to engineering materials is also provided to guide students to select proper materials for their process design and future applications. Considering that most industry relies on technology, and the world is in patent war, an introduction to intellectual property will be given.
