School:School of Computing, Engineering and Physical Sciences
Module Co-ordinator:Mojtaba  Mirzaeian

Summary of Module

In this module:

  • Liquid-liquid extraction (LLE) covers immiscible solvents, determination of number of stages, transfer unit approach, partially miscible systems, choice of solvents (taking into account hazards such as toxicity and flammability as well as ability to dissolve), and use of triangular diagrams.
  • Gas absorption examines the calculation of the number of ideal stages required for the separation of dilute solutions, the calculation of packed height for dilute solutions and the calculation of pressure drop across the packed bed. The topic then extends into the calculation of packed height for concentrated solutions.
  • Filtration covers the derivation of the Ruth equation, cloth resistance, constant rate and constant pressure filtration. Application of filtration theory to common types of industrial filters. Application of Ruth’s equation to centrifuges.
  • Drying covers both batch and continuous processes with relation to the changing drying rate of a solid as time progresses. Various items of drying equipment are also discussed.
  • Size classification and size reduction of solids covers mass balances over a screen to determine the oversize effectiveness, undersize effectiveness and overall effectiveness of the screen.  Von Rittinger's, Kick's and Bond's laws to calculate required power for size reduction, mechanical and crushing efficiencies are introduced and work index, energy of size reduction and size reduction equipment are discussed.

This module will work to develop a number of the key 'I am UWS' Graduate Attributes to make those who complete this module: Universal (Critical Thinker, Ethically-minded, Research-minded); Work Ready (Problem-Solver, Effective Communicator, Ambitious); Successful (Autonomous ,Resilient, Driven).

Face-To-Face
Term used to describe the traditional classroom environment where the students and the lecturer meet synchronously in the same room for the whole provision.

Blended
A mode of delivery of a module or a programme that involves online and face-to-face delivery of learning, teaching and assessment activities, student support and feedback. A programme may be considered “blended” if it includes a combination of face-to-face, online and blended modules. If an online programme has any compulsory face-to-face and campus elements it must be described as blended with clearly articulated delivery information to manage student expectations

Fully Online
Instruction that is solely delivered by web-based or internet-based technologies. This term is used to describe the previously used terms distance learning and e learning.

HybridC
Online with mandatory face-to-face learning on Campus

HybridO
Online with optional face-to-face learning on Campus

Work-based Learning
Learning activities where the main location for the learning experience is in the workplace.

Learning Outcomes: (maximum of 5 statements)

On successful completion of this module the student will be able to:

L1. Understand how to select an appropriate separation process for a given multiphase separation problem considering the principles of equilibrium, mass transfer and their application to phase behaviour, equipment sizing and performance.

L2. Produce a design for one of the fluid-fluid or fluid particle separation processes described using published data/information to quantify the effect of processing steps on the state of the material being processed, and its transformation to the end product.

L3. Understand the limitations of approximate design methods and how these can be improved/extended by use of computer software packages and digital techniques to solving Chemical Engineering Problems. .

L4. Appreciate the characteristics of masses of particulate solids and understand how to determine the screen effectiveness as a measure of the successes of a screen in separating solid particles.

Learning and Teaching
This module covers a variety of theoretical, conceptual and practical areas, which require a range of knowledge and skills at a more advanced level to be displayed and exercised. Delivery of its syllabus content therefore involves a diversity of teaching and assessment methods suitable to the learning outcomes of the module; these include formal lectures, structured tutorials (work closely integrated with the lecture material), laboratory exercises to develop practical skills and familiarisation with equipment and experimental techniques, completion and submission of written coursework making use of appropriate forms of IT and VLE, and independent study.

Hours for the exam and class tests are included in lecture/core content delivery.
Learning Activities
During completion of this module, the learning activities undertaken to achieve the module learning outcomes are stated below:
