CME3025 : Energy and Material Balances for Scientists

  • Offered for Year: 2013/14
  • Module Leader(s): Dr Jonathan Lee
  • Owning School: Chemical Eng & Advanced Materials


Semester 1 Credit Value: 10
ECTS Credits: 5.0


To introduce students to the principles of material and energy balances and the formulation and solution methods for material and energy balance problems.

To provide the opportunity to extensively practice the principles and techniques of solving problems involving material and energy balances in a supportive environment.

This module teaches the fundamentals of Energy and Material Balances as these methods form the basis of chemical process design. Material balances set process inlet and outlet flows and compositions while energy balances determine the energy (heating, cooling and power) requirements for a process.

Outline Of Syllabus

Review of the laws of conservation and their applicability in solving material and energy balances under steady and unsteady state will be given in lectures supported by handouts. Mass balances around single and linked items of plant. Mass balances with chemical reaction. Recycle and bypass streams. Energy balances. Simultaneous mass and energy balances. Emphasis is given to illustration of these issues through practical solving of problems both during lectures and tutorials.
