Mass and energy balance calculations are the essential parts of the solution of many complex chemical engineering problems. They assist in the planning and design of processes, in the economic evaluation of the proposed and existing processes, in process control, and in process optimization. In this course, students will learn a systematic procedure for solving mass and energy balance problems including drawing and labelling for a flowchart, performing a degree-of-freedom analysis, making appropriate chemical engineering assumptions etc. Students will be able to analytically examine and predict the mass and energy balances around single or multiple unit operation(s) involving gases and liquids, recycle, bypass or purge streams with or without chemical reactions.

This course seeks to develop the following knowledge and skills in students: Mass balanceStudents will be able to analyse and perform:o Units conversion, mass/molar/volumetric flowrates, mass/mole fractions, total and component balanceso Steady-state/unsteady-state, batch/continuous processeso Tie element, basis for calculation, flowchart labellingo Independent mass balance equations and Degree-of-Freedom analysiso Steps for solving mass balance problemso Mass balance with/without chemical reactions Energy balanceStudents will be able to analyse and perform:o Energy conservation and balance equationso Energy balances involving temperature changeo Energy balances involving phase changes and steamo Energy balances involving reactions (isothermal and non-isothermal)
Subject to approval of the Dean of Engineering and Forestry.
The course consists of three lectures (3 x 1 h) and one HelpDesk session (1 h) per week. Tutorial sessions will be run within the lecture occasionally. Attendance at all lectures is highly encouraged.
