Distillation Design

• Vapor–liquid equilibrium: Vapor–liquid K values, relative volatilities, ideal and non-ideal systems, phase diagrams, calculating bubble points and dew points
• Key fractional distillation concepts: theoretical stages, x-y diagrams, multicomponent distillation, column composition and temperature profiles
• Process design and optimization: minimum reflux and minimum stages, optimum reflux, short-cut methods, feed entry location
• Rigorous calculation methods: Bubble point method, sum rates method, numerical methods, inside out method, relaxation method, other methods
• Batch distillation: Simple distillation, constant reflux, varying reflux, time and boilup requirements
• Tray design and tray efficiency: tray types, tray capacities, tray hydraulic parameters, tray sizing and determination of column diameter, point and tray efficiencies, tray efficiency prediction and scaleup
• Packing design and packing efficiency: packing types, packing hydraulics and capacities, determination of packing efficiency by transfer unit method and by HETP method, packed column sizing
