PE1812: Material and Energy Balances

Credit Weighting: 5
No. of Students: Min 6, Max 35.
Pre-requisite(s): None.
Co-requisite(s): None.
Teaching Period(s): Semester 1.
Teaching Methods: 12 x 1hr(s) Lectures (blended learning)
Module Co-ordinator: Dr Denis Ring, Department of Process and Chemical Engineering.
Lecturer(s): Mr Vincent Irwin, Department of Process and Chemical Engineering; Staff, Department of Process and Chemical Engineering, and guest lecturers.
Module Objective: To develop an understanding of material and energy balances and their applications to process and plant design.
Module Content: Law of conservation of mass, open and cloased systems, system boundary, batch and continuous processes, material balance equations, material recycle. Law of conservation of energy, forms of energy, development of energy balance equations, process applications, reading and using steam tables.
Learning Outcome: On successful completion of this module, students should be able to:
  • Describe the nomenclature associated with material and energy balances.
  • Identify and schematically draw the material flows associated with a material balance.
  • Identify and schematically draw the energy flows associated with an energy balance.
  • Write and solve the material and energy balance equations associated with typical chemical engineering processes.
  • Carry out the preliminary material and energy design work on a process in order to enable the construction of a process flow diagram.
  • Find thermodynamic properties of steam/water systems using steam tables.
Assessment: Total Marks 100: Formal Written Examination 70 marks; Continuous Assessment 30 marks (2 x 2,500-3,000 word essays, projects, assignments or equivalent, 15 marks each).
Compulsory Elements: Formal Written Examination; Continuous Assessment.
Penalties (for late submission of course/project work etc.): Where work is submitted up to and including 7 days late, 10% of the total marks available shall be deducted from the mark achieved. Where work is submitted up to and including 14 days late, 20% of the total marks available shall be deducted from the mark achieved. Work submitted 15 days late or more shall be assigned a mark of zero.
Pass Standard and any Special Requirements for Passing Module: 40% and at least 30% in both the written examination and the continuous assessment.
End of Year Written Examination Profile: 1 x 1.5 hr(s) paper(s) (open book written examination) to be taken in Winter 2021.
Requirements for Supplemental Examination: 1 x 1.5 hr(s) paper(s) (open book written examination) to be taken in Autumn 2022. The mark for Continuous Assessment is carried forward (unless a grade of less than 30% has been achieved in which case the student will be invited to resubmit their continuous assessment in the autumn).
