NTRODUCTION TO THE STUDY OF UNITARY OPERATIONS AND TRANSPORT PHENOMENA • Classification of unit operations: Unitary Operation based on thermodynamic, physical / mechanical and kinetic properties. • Transport Phenomena: Molecular transport: steady state generalized molecular transport equation, application of molecular transport in stationary conditions, molecular transport in non-stationary conditions. Turbulent transport: Reynolds experiment, velocity distribution in turbulent flow, turbulent diffusivity model, analysis of the mechanism ratio, friction factor and Reynolds number, boundary layer and resistance of the medium, motion of fluids through granular solids, mass and heat transfer. Transfer between multi-phase: heat transfer, mass transfer 2. UNITARY OPERATIONS BASED ON THERMODYNAMIC PROPERTIES • Heat Exchangers: Construction and operation of heat exchangers. Sizing of heat exchangers: energy balance, the logarithmic mean temperature difference, comparing equi-current and countercurrent, design of shell and tube exchangers. • Absorption: Construction and operation of absorption columns. Calculation of the diameter of a packed absorption column. Calculation of the height of filling in an absorption column: method of transfer unit, calculating the number of transfer units, transfer unit height calculation, calculation of optimum L/V ratio • Distillation: Construction and operation of plate distillation columns. Liquid-vapor equilibrium. Calculation of the diameter of a distillation column with plates: calculation of the spacing between the plates, calculation of the diameter. Calculation of the number of plates in a distillation column: working curves, calculating the number of theoretical plates, simplified graphical method of McCabe-Thiele, Fenske method, graphical method of Ponchon-Savarit, determining the efficiency of a plate distillation column. Steam distillation. • Solvent extraction: Liquid-liquid solvent extraction: design features and operation of the liquid-liquid extractor, liquid-liquid equilibria, two component systems, three-component systems, calculating the number of theoretical stages of extraction, multiple stages with crossed current, multiple-stage countercurrent without reflux, multiple-stage countercurrent with reflux, design criteria. Solid-liquid solvent extraction (outline).
