This application provides design and cost estimation for multicomponent distillation columns. The equations and correlations involved in the design phase are Fenske, Underwood, Erbar-Maddox, O'Connell, Kirkbride, and Fair. Vapor-Liquid disengagement area at top and 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. The 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). All affecting 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%. Note, copy-paste, comparison, and sensitivity analysis can be simply handled through this application.
