15 points, 0.1250 EFTS
22 Feb 2016 - 26 Jun 2016

Description

An introduction to completing mass and energy balances on systems relevant to process technologies.

Topics

Mass Balances (Dr. Gabriel A. Visnovsky)

 Weight volume and molar compositions of gas, liquid and solid mixtures.  Choice of convenient basis for solving problems.

 Material Balances of chemical processes.  Classification of processes.  General material balance equation.  Methods for solving material balances.  Balances on non-reactive systems.

 Material balances on reactive systems.  The chemical equation and stoichiometry.  Yield, Selectivity, Conversion.

 Material Balance of Systems with Chemical Reactor.  Recycle, Bypass and Purge streams.  Solving Material Balances.

 Combustion of Fuels.  Combustion process and terminology.  Excess air and gas analysis.  Material balances for combustion processes.

 Simultaneous equations in mass balances (Dr Aaron Marshall)

Energy Balances (Dr. Aaron Marshall)

 Energy conservation and balance equations

 Energy balances involving temperature change

 Energy balances involving phase changes and steam

 Energy balances involving reactions (isothermal and non-isothermal)

 Simultaneous equations in energy balances

Pre-requisites

Subject to approval of the Dean of Engineering and Forestry.

Timetable Note

Course policy on collaboration and cheating:

Solving problems in small teams and collaborative learning when working on assignments is encouraged. However direct copying is plagiarism and will result in zero marks for all students involved. When assessment is distributed, you will be instructed whether the assessment is to be submitted for marking individually or as part of a pair/group.
The assignments are mainly a tool to prepare you for the exams.  The advice is to try them individually before collaborating in groups.
