Acetic acid dehydration is an important operation in the production of aromatic acid, such as
terephthalic acid or in the manufacture of cellulose acetate. Although acetic acid and water …

The aim of this work is to implement heterogeneous azeotropic distillation schemes in a
dividing wall column (DWC) for a feed mixture of water (W), acetic acid (HAC) and an …

The separation of azeotropes has substantial energy and investment costs, and the
available methods require high capital costs for reconstruction of process plants. As an …

In the production of pure terephthalic acid, a tiny amount of reactant p-xylene and byproduct
methyl acetate may enter into the acetic acid dehydration system through the feed stream. In …

This paper presents a new unified model that allows the simulation of distillation columns
with any integer number of phase divisions. Such columns have the potential for substantial …

In our previous study [Chien, IL, Zeng, KL, Chao, HY, Liu, JH (2004). Design and control of
acetic acid dehydration system via heterogeneous azeotropic distillation. Chemical …

A dividing‐wall column (DWC) may have more than one solution of liquid and vapor split
ratio for the same feed and product streams under a fixed number of stages and reflux ratio …

In this work, an industrial acetic acid dehydration system via heterogeneous azeotropic
distillation is simulated by Aspen Plus software. Residue curves are used to analyze the …

Dynamic model for dehydration process of industrial purified terephthalic acid solvent is
investigated to understand and characterize the process. A temperature differential …

In this work, the design and operation of an industrial column for acetic acid dehydration via
heterogeneous azeotropic distillation is investigated. Multiple column feed streams from …
