Dividing wall column (DWC) is a single shell, fully thermally coupled distillation column
capable of separating mixtures of three or more components into high purity products …

Distillation is a common energy-intensive process. Accordingly, it is the rst process to be
addressed to improve the energy e ciency over both the short-and long-term. Recent studies …

A novel extractive distillation system is presented. The proposed separation system evolves
from an extractive thermally coupled system with a side rectifier. Specifically, the …

This paper proposes a novel extractive dividing wall distillation column, which has been
designed using a constrained stochastic multiobjective optimization technique. The …

A natural gas liquefaction and liquid recovery sequence is proposed for top-side offshore
floating liquefied natural gas processing. During liquefaction, a single mixed refrigerant is …

The dividing-wall distillation column is thermodynamically equivalent to the Petlyuk column
on the condition that no heat transfer is allowed across the dividing wall. However, better …

In this paper, design and optimization procedures are developed for a conventional
extractive distillation sequence and a thermally coupled extractive distillation scheme. The …

We performed steady state and dynamic simulations of a reactive Petlyuk column through an
equivalent reactive dividing wall column (RDWDC). In the case of the reaction between …

Distillation columns are one of the main methods used for separating air components. Their
inconvenient is their high energy consumption. The distillation process is simulated in three …

This paper introduces a novel MILP approach for the design of distillation columns
sequences of zeotropic mixtures that explicitly include from conventional to fully thermally …
