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.
This course provides an introduction to process design. The course introduces the Douglas hierarchical design philosophy and the use of process simulators to aid in process design. The course builds on the material taught throughout the 1st professional year, especially the concepts of material and energy balances. Here these concepts are extended to the design of more complex processes. The design of specific unit operations is introduced by providing a detailed introduction to heat exchanger design. The course also builds on the process safety material taught in ENCH295 to look at consequence modelling and techniques for risk reduction in process safety. An introduction to engineering materials for chemical engineers is also provided. Course Content • Introduction to Process Design (Daniel Holland, 4L, 1 Assignment) • Process Safety (consequence modelling, risk reduction and legal framework) (Heon Park, 9L, 1 Test) • Heat Exchanger Design (Heon Park, 6L, 1 Assignment) • UNISIM Software Package Training (Daniel Holland, 3 Computer Lab Tutorials, 1 Assignment) • Introduction to Engineering Materials (Heon Park, 15L, 2 Quizzes, 1 Exam)
