iPhone app Distillator

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, OConnell, 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).
