Solids Processing

CHEN20061 Solids Processing 10 Semester 1 Undergraduate Level 2 Mauro Luberti Unit coordinator Thomas Rodgers Unit coordinator Department of Chemical Engineering 1 FHEQ level (Framework for Higher Education Qualifications) ' Middle part of Bachelors ' European Credit Transfer & Accumulation System Rating : 5.0 The unit consist of seven main topics:Topic 1 - Particle characterization: in this topic the methods used to describe particle size and shape are introduced. The focus will be on particle size distributions and definitions of shape.Topic 2 - The motion of a single particle in a fluid: in this topic the concepts of particles moving in a fluid will be discussed. The focus will be on how to describe and evaluate the motion of particles through a fluid.Topic 3 - Sedimentation – settlers and thickeners: in this topic the concepts of particles settling under gravity are explored. The focus will be on how to design industrial settlers and thickeners using knowledge of particle motion in a fluid.Topic 4 - Centrifuges and Cyclones: in this topic the methods to enhance particle settling are explored. The focus will be on how to design centrifuges and cyclones for industrial processes using key design methodologies including Sigma theory and Stairmand’s design procedure.Topic 5 - Fluid flow through packed beds: in this topic the basic principles of fluid flow through granular and packed beds of particles are introduced. The focus will be on how to describe, evaluate and analyse fluid flow through a bed of stationary particles using Darcy’s law and other empirical equations such as Ergun, Blake-Kozeny, Kozeny-Carmen, etc.Topic 6 - Filtration: in this topic the basic concepts of filtration is introduced. The focus will be on how to describe from fundamental principles fluid flow through a cake and medium filter system and how to design this unit operation.Topic 7 - Fluid flow through fluidized beds: in this topic the main principles of fluidization and flow through fluidized beds are presented. The focus will be on how to describe the process of fluidization, the different fluidization regimes, Gerdart’s classification and fluidized bed. Furthermore, analyses and evaluation of how to estimate the minimum and maximum fluidization velocity and the benefit of pneumatic conveying will be presented.  The unit consist of seven main topics:Topic 1 - Particle characterization: in this topic the methods used to describe particle size and shape are introduced.

Students will be able to:  ILO1: Use methods to characterise solid particle sizes and shapes.ILO2: Describe the motion of solid particles in a fluid-solid system.ILO3: Design gravity solid separating units such as settlers, thickeners, and filters.ILO4: Design force enhanced solid separating units such as centrifuges and cyclones.ILO5: Develop mathematical expressions to describe, evaluate, and analyse fluid flow through a bed of stationary and fluidized particles. Fundamental aspects supporting the critical learning of the module will be delivered as pre-recorded asynchronous short videos via our virtual learning environment. These will be supported by synchronous sessions with master lecture content, Q&A, and problem-solving sessions where you can apply the new concepts.  Surgery hours are also available for drop-in support.Feedback on problems and examples, feedback on coursework and exams, and support will also be provided through the virtual learning environment. A discussion board provides an opportunity to discuss topics related to the material presented in the module.Students are expected to expand the concepts presented in the session and online by additional reading (suggested in the Online Reading List) in order to consolidate their learning process and further stimulate their interest to the module. Teaching activitiesCore Learning Material (e.g. recorded lectures, problem solving sessions) - 24 hoursContinuous Assessment - 21 hoursSelf-Guided Work (e.g. extra problems, reading) 30 hoursExam Revision/Preparation - 25 hoursTotal for Module - 100 hours 0 Other 100% <figure class="table"><table><tbody><tr><td style="border:1.0pt solid windowtext;padding:0cm 5.4pt;vertical-align:top;width:276.2pt;" width="368">Assessment Types</td><td style="border-bottom-style:solid;border-color:windowtext;border-left-style:none;border-right-style:solid;border-top-style:solid;border-width:1.0pt;padding:0cm 5.4pt;vertical-align:top;width:184.25pt;" width="246">Total Weighting</td></tr><tr><td style="border-bottom-style:solid;border-color:windowtext;border-left-style:solid;border-right-style:solid;border-top-style:none;border-width:1.0pt;padding:0cm 5.4pt;vertical-align:top;width:276.2pt;" width="368">Continuous Assessment (ILOs 2,3)</td><td style="border-bottom:1.0pt solid windowtext;border-left-style:none;border-right:1.0pt solid windowtext;border-top-style:none;padding:0cm 5.4pt;vertical-align:top;width:184.25pt;" width="246">50%</td></tr><tr><td style="border-bottom-style:solid;border-color:windowtext;border-left-style:solid;border-right-style:solid;border-top-style:none;border-width:1.0pt;padding:0cm 5.4pt;vertical-align:top;width:276.2pt;" width="368">Final Exam (ILOs1,2,4,5)</td><td style="border-bottom:1.0pt solid windowtext;border-left-style:none;border-right:1.0pt solid windowtext;border-top-style:none;padding:0cm 5.4pt;vertical-align:top;width:184.25pt;" width="246">50%</td></tr></tbody></table></figure> BEng(Hons) Chem Eng BEng(Hons) Chemical Engineerin Second Year Optional MEng (Hons) Chem Eng MEng Chemical Engineering Second Year Optional MEng (Hons) Chem Eng w I E MEng (Hons) Chem Eng w I E Second Year Optional MEng Chem Eng w Energy & Env MEng Chem Eng with Energy Second Year Optional N Reading lists are accessible through the Canvas system linked to the library catalogue.
