CHEN20061 Solids Processing 10 Semester 1 Undergraduate Level 2 Mauro Luberti Unit coordinator Thomas Rodgers Unit coordinator 1 FHEQ level (Framework for Higher Education Qualifications) ' Middle part of Bachelors ' European Credit Transfer & Accumulation System Rating : 5.0 <div><div><p>The unit consist of six main topics:</p><ol> <li>Particle characterization and the motion of a single particle in a fluid: in this topic the methods used to describe particle size and shape are introduced and linked to how these particles move in a fluid. The focus will be on how to describe and evaluate the motion of particles through a fluid.</li> <li>Sedimentation &ndash; 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.</li> <li>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&rsquo;s design procedure.</li> <li>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&rsquo;s law and other empirical equations such as Ergun, Blake-Kozeny, Kozeny-Carmen, etc.&nbsp;</li> <li>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&rsquo;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.</li> <li>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.</li></ol></div></div> <div><div><p>The unit consist of seven main topics:</p><p>Topic 1 - Particle characterization: in this topic the methods used to describe particle size and shape are introduced.
