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 2nd 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 to guide students to select proper materials for their process design and future applications. Course Content • Introduction to Process Design (Daniel Holland, 4 lectures, 1 assignment) • Process Safety (consequence modelling, risk reduction and legal framework) (Rachael Wood, 9 lectures, 1 test) • Heat Exchanger Design (Heon Park, 6 lectures, 1 assignment) • UNISIM Software Package Training (Daniel Holland, 3 computer lab tutorials, 1 assignment) • Introduction to Engineering Materials (Heon Park, 15 lectures, 1 computer lab tutorial, 2 quizzes, 1 exam

Course Policies on Collaboration and Cheating:Solving problems in small teams and collaborative learning when working on assignments is encouraged. However direct copying will result in reduced or zero marks for all students involved. The assignments are mainly a tool to prepare you for the exams. We advise you to try them individually before collaborating in groups.Laboratories: There are computer-based labs and tutorials will be provided. Assessments will be given with problems which need to utilise the computer software.Wrong units or missing units in answers unless these are dimensionless: Zero point will be given to the problemMarked assignments will be released before study break for exam

ConcernsStudents may obtain the general policies of the University from the website. For example:Special considerations: http://www.canterbury.ac.nz/study/special-consideration/ Academic Appeals of Assessments: Students with concerns about course teaching, assessment processes, or grades should speak first with the relevant lecturer or the course coordinator. If the matter cannot be resolved, then the student can meet the 3rd year Director. If the matter still cannot be resolved, the student can discuss the matter with the Head of Department and thereafter follow the procedures outlined in the University procedures http://www.canterbury.ac.nz/media/documents/postgraduate-/Academic-Appeals-Grievances-Principles-Procedures.pdf and regulations https://www.canterbury.ac.nz/regulations/general-regulations/academic-appeals-and-grievances/Reconsideration of grades: If you are concerned that your final grade may be incorrect, it is suggested (for CAPE) that you make an informal query to the course coordinator, but you may follow the official procedures: http://www.canterbury.ac.nz/study/examinations/result-dates-and-appeals/ Disabilities: http://www.canterbury.ac.nz/disability/
Relation to Other CoursesThis course builds on the concepts introduced throughout the 2nd Year. It serves as preparation for final-year design, ENCH494.Course Requirements:Submission of all assignments, test, and exam is mandatory to pass this course. Students Contributions:Students are expected to study on this course at least 10 hours per each week. Lectures provide only the skeleton of the materials to be learned. Once each lecture is taught, students should study and review by themselves to achieve learning outcomes by utilising all methods and resources. Students are also expected to source materials for their study.
Course Policies on Collaboration and CheatingSolving problems in small teams and collaborative learning when working on assignments is encouraged. However, partial or full, direct copying sources from peer or literature will result in zero mark for the assignment. Students, who provided or shared their findings (raw data, solutions, etc.), will fail this course. The assignments are mainly a tool to prepare students for more complex problems. We advise you to try them individually before collaborating in groups.General Policies of the DepartmentStudents may obtain the general policies of the University on matters such as special consideration applications, appeal procedures, reconsideration of grades and special provision for students with disabilities from the University Calendar

Students' attendance is not mandatory but highly encouraged.Lectures will be video-recorded, and the videos will be available up to two weeks from the lecture time. However, the technical quality of the videos will be not guaranteed. Thus, students are highly suggested to attend all the lectures.A hard copy or electronic version of lecture notes or slides may not be released prior to each lecture, and thus students should try to take their own notes during or/and after each lecture.
Late submissions will lose 10% grade per day overdue
