Shortcut methods for complex distillation columns : part 1 -- Minimum reflux

Shortcut Methods for Complex Distillation Columns: Part 1 -Minimum Reflux This two-part paper presents in detail the theory for calculating via shortcut methods the minimum reflux conditions and the number of stages and feed tray location for ordinary and thermally coupled columns. Nonadjacent key components are permitted. In this paper, part 1, the approximations made to estimate minimum reflu...

Minimum Energy Consumption in Multicomponent Distillation. 1. Vmin Diagram for a Two-Product Column

The Vmin diagram is introduced to effectively visualize how the minimum energy consumption is related to the feed-component distribution for all possible operating points in a two-product distillation column with a multicomponent feed. The classical Underwood equations are used to derive analytical expressions for the ideal case with constant relative volatility and constant molar flows. Howeve...

A Short Method for the Design of Reactive Distillation Column

In this study, a short method for the design of reactive distillation is presented. The method is based on distillation lines and tray-by-tray calculations, and a new strategy is suggested to locate the reflux ratio, the number of stages, and feed tray. The material balances are solved from the outside (top and bottom) to the inside of the distillation column (feed), to ensure that the product ...
