|Subject Overview:|| |
Students successfully completing this subject will be able to apply the principles of heat transfer to convective heat transfer problems, heat exchanger and evaporator designs, and to analyse and design equilibrium stage and continuous contactor separation operations including simple distillation, gas absorption and liquid extraction.
Heat Transport Processes Convection: use of heat transfer correlations to predict coefficients; concept of an overall heat transfer coefficient, fouling factors; determination of the area required for a given heat duty. Use of simulation packages such as HYSYS and ASPEN. Free convection: discussion and application of Grashof Number and other dimensionless groups. Heat exchanger design. Basics of condensation and boiling. Evaporation: various evaporator types and their advantages and disadvantages (forced circulation, film types); multiple and single effects; backward and forward feed; boiling point elevation; mechanical recompression; evaporator energy Âbalances.
Mass Transport Processes: Unsteady state mass transfer and Fick's Second Law; prediction of diffusivity; dimensional analysis and equations of change for mass transfer. Definition of separation processes, separating agents, separation factors, equilibrium and rate type processes, equilibrium stage, non-equilibrium performance. Equilibrium stage processes - Distillation: single-stage separations, equilibrium flash, differential distillation; multistage separations, operating lines, reflux; binary distillation, varying reflux ratio, minimum reflux, total reflux, optimum reflux, feed plate location, side streams, open steam; tray efficiency via overall and Murphree efficiencies. Use of simulation packages such as DISTIL- Gas absorption: basic mass transfer mechanism; material balances, co-current and countercurrent flow, limiting L/G ratio; multistage absorption and the absorption factor method; continuous contact, transfer units, height of a transfer unit, calculation of number of transfer units. Humidification and cooling tower height calculation.Liquid Extraction: applications of liquid extraction, liquid-liquid equilibria; single-stage extraction, choice of solvent/feed ratio; multistage cross-current extraction; continuous counter-current multistage extraction. Continuous contact operations.
|Assessment:||One written 3-hour end-of-semester examination (70%); a 90-minute written class test one third of the way through the semester (20%); and an assignment expected to take about 10 hours due two thirds of the way through the semester (10%). An overall mark of 50% and a mark of 40% or more in the end of semester examination are needed to pass the subject.|
