Pinch Analysis Applied to Atmospheric Distillation Column

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...

A Systematic Approach to Distillation Column Control

This paper presents a systematic approach to distillation column control. The main emphasis is on the steps which precede the actual controller design, namely the modelling of the column and the selection of the control con guration. By control con guration in this context we mean the two independent variables used for composition control (for example, L and V;D and V , or L D and V B ). The st...

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...
