Aims

To give participants an understanding of the separation technologies used in the process industries.
To provide an introduction to phase equilibria and enable this to be applied to the design of selected separation processes and plant equipment.

To understand the technology and design methods used for the solution of separation problems in the process industries.

To develop techniques necessary to specify and design separation processes for both equilibrium and rate controlled separations.

Outline Of Syllabus

Distillation:

Vapour liquid equilibrium and equilibrium stage calculations.
Calculating the number of stages in a distillation column, reflux ratio and the effect of the condition of the feed.
The design of column internals, hydraulic design for trays and packing.

Gas Absorption/Stripping:

Mass transfer in continuous contact separation processes.
Calculating the height of packed columns.
The effect of temperature and pressure on gas absorption and stripping.

Solvent Extraction:

Liquid-liquid equilibrium, single equilibrium stage extraction calculations.
Cross flow and counter flow cascades.

Drying:

The terminology of humidification.
Use of psychometric charts.
Mass (moisture) balances for humid systems.
Drying curves, constant rate drying, falling rate drying and the mechanisms of solids drying.
Understand the issues of dryer design and choice of the correct dryer design for given applications.

Teaching Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

Teaching Rationale And Relationship

Lectures introduce theoretical concepts practiced in tutorials. The case study enables a realistic engineering problem to be solved.
Students should consult their individual timetable for up-to-date delivery information.

Assessment Rationale And Relationship

The exam will test the students' understanding of the separations technology they have learned about during the lectures and their knowledge of separation process design methods.

The case study will enable the concepts of separation to be brought to the selection; design and performance estimation of a separation process as part of a team design exercise.
