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:Process Design (4L, 1 Assignment, Ben Yin)o considerations in process designo hierarchical concept in process designo how to utilise mass balance in process designo Analysis on economic performance Safety (9L, Test, Rachael Wood)o consequence modellingo risk reduction o legal frameworkPinch analysis (4L, 1 Quiz, Erskine Guest Lecturer Grant Campbell)o various methods to perform pinch analysiso how to integrate process to maximize energy recoveryo estimating energy saved by system integrationUniSim (1L, 3 Computer Labs, 1 Assignment)o computer-aided designingo optimising designed processo comparison with hand-designed processMaterials (18L, 2 Quizzes, Exam, Kai Sellschopp)o Material properties: mechanical, chemical, physicalo Structure of materials - from atoms to the microscaleo Classes of Materials: Steel and other Metals, Polymers, Ceramics, Glasses, etc.o How to select the right material for an applicationo How to use materials databases

ENCH291
Students must attend one activity from each section.
32 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 content, studying textbooks and references, making own notes, and preparing for labs. Students are also expected to spend 10 hours per 10% of assignment weighing.
