Energy Integrated Distillation Column Sequence by Driving Force Method and Pinch Analysis for Five Components Distillation

Distillation pinch points and more

Rising energy costs have spawned renewed interest in improving methodologies for the synthesis, design and/or retrofitting of separation rocesses. It is well known that energy use in many process industries is dominated by separation tasks—particularly distillation. In this work, the hortest stripping line approach recently proposed by Lucia, Amale, & Taylor (2006) is used to find minimum energ...

Energy targeting and minimum energy distillation column sequences

The determination of distillation column configurations that consume the least total energy is studied. The novel contributions of the proposed designmethodology for finding globalminimum energy column sequences presented in this article include: (1) the definition of a total stripping line distance function for any sequence, (2) a robust energy targeting strategy that provides a continuously d...

Integrated Column Designs for Minimum Energy and Entropy Requirements in Multicomponent Distillation

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 ...

Simulation Of Reactive Distillation Column

Reactive distillation processes couple chemical reactions and physical separations into a single unit operation. The ethyl acetate production by esterification reaction is equilibrium limited and is suitable to be carried out in a distillation column. In the present work, a reactive distillation column for the production of ethyl acetate is simulated using Aspen Plus. The component compositions...
