CHEM ENG 2010 - Process Design II

North Terrace Campus - Semester 1 - 2022

Design of chemical processes starts by properly formulating and solving material and energy balances for whole process flowsheets. In this course, the concepts covered in CHEM ENG 1007 Introduction to Process Engineering are built upon to include multiple units, both reactive and non-reactive systems, single and multiple phases, and steady state and transient processes. More fundamentally, it introduces problem solving strategies used by chemical engineers to solve large and more complex problems by breaking a process down into its components, establishing the relations between known and unknown process variables, assembling the information needed to solve for the unknowns, and finally obtaining the solution using appropriate computational methods. This will be reinforced by undertaking a process design project in small teams. This course is delivered through a combination of online theory lectures, practice workshops, tutorials, and process design sessions.

On successful completion of this course students will be able to:

1	Use a generalised problem solving strategies to solve a range of material and energy balances
2	Formulate and solve material balances for steady state and transient processes, single and multiple unit operations, with and without chemical reactions, and for single and multiphase situations.
3	Formulate and solve energy balances for mechanical energy situations, with and without chemical reactions.
4	Understand the basics behind economic analysis of a proposed process design

The University's policy on Assessment for Coursework Programs is based on the following four principles:

Assessment must encourage and reinforce learning.
Assessment must enable robust and fair judgements about student performance.
Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
Assessment must maintain academic standards.

Student Feedback

The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Fraud Awareness

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.

The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
