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 2nd year and ENCH390 Process Design 1 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 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.

The following topics are taught in this course:
Safety (9L, 1 test, Rachael)
o consequence modelling
o risk reduction
o legal framework
Pinch analysis (5L, exam, Heon)
o various methods to perform pinch analysis
o how to integrate process to maximize energy recovery
o estimating energy saved by system integration
Process Design (4L, 1 assignment, Heon)
o considerations in process design
o hierarchical concept in process design
o how to utilise mass balance in process design
o Analysis on economic performance
Unisim (3L, 1 assignment, Heon)
o computer-aid designing
o optimising designed process
o comparison with hand-designed process
Intellectual property (3L, exam, Heon)
o Various types
o How to set up IP strategy
o How to avoid infringing other IPs
o How to search for prior IPs
o How to utilise prior IPs in the beginning of research or development and for problem solving
Materials (15L, 2 quizzes, exam, Heon)
o Mechanical properties
o Chemical properties
o Metals
o Polymers
o Ceramics, glasses
o Fibres, films, foams, insulators
o Selecting proper materials given applications

  • Performing simple economic analysis
  • Approaching problems rationally
  • Sourcing necessary information, data, literature, equipment, and materials


Timetable Note

36 lectures and 4 computer labs/tutorials.

Students are expected to attend all lectures or to study Echo360 videos in case attending is not possible, spend 10 hours per week reviewing lecture contents, studying textbooks and references, making own notes, and preparing for labs. Students are also expected to spend 10 hours per assignment weighing 10%.

Students should consider mid-semester break as catching up time, not holidays. Thus, this period should be utilised for reviewing, previewing, and preparing for assessments.
