• Multicomponent Distillation Columns: Accurate Design + Economical Assessments

• This software provides design, sensitivity analysis, and cost estimation of multicomponent distillation columns. 
• Define your own system of multicomponent (2-40 component) distillation and see the products and economic evaluations.
• The most reliable equations and correlations are being used here for design calculations. 
• The models involved in the design phase are Fenske, Underwood, Erbar-Maddox, O'Connell, Kirkbride, and Fair. 
• The vapor-Liquid disengagement area at top and a liquid residence time of 5 min at bottom are considered while calculating the height of column.
• The Purchased Cost and the Bare Module Cost are estimated for years ranged from 1957 to present. 
• All affecting economic parameters, i.e. size, pressure, temperature, materials of construction, and inflation are taken into account.
• Thanks to incorporating average values of published cost data, the estimation accuracy is at a high level of ±12%.
• The cost estimation method is adopted from Turton et al. (2018) who reviewed and updated the modular technique and cost data proposed by Guthrie (1974) and Ulrich (1984).
