Title: Relaxing the constant molar overflow assumption in distillation optimization

Abstract

Abstract The constant molar overflow (CMO) framework, while useful for shortcut distillation models, assumes that all components have the same latent heats of vaporization. A simple transformation, from molar flows to latent‐heat flows, allows shortcut models to retain the mathematical simplicity of the CMO framework while accounting for different latent heats, resulting in the constant heat transport (CHT) framework for adiabatic distillation columns. Although several past works have already proposed this transformation in the literature, it has not been well utilized in recent times. In this article, we show the utility of this transformation in upgrading various applications such as identifying energy‐efficient multicomponent distillation configurations based on heat duty rather than surrogate vapor flow. The method transforms the diagram to a diagram. Furthermore, we derive new and insightful analytical results in distillation, such as cumulative latent‐heat stage fractions having monotonic profiles within a distillation column under the CHT framework.

Short-cut Methods versus Rigorous Methods for Performance-evaluation of Distillation Configurations

Journal Article Ramapriya, Gautham Madenoor ; Selvarajah, Ajiththaa ; Jimenez Cucaita, Luis Eduardo ; ... - Industrial and Engineering Chemistry Research

This study demonstrates the efficacy of a short-cut method such as the Global Minimization Algorithm (GMA), that uses assumptions of ideal mixtures, constant molar overflow (CMO) and pinched columns, in pruning the search-space of distillation column configurations for zeotropic multicomponent separation, to provide a small subset of attractive configurations with low minimum heat duties. The short-cut method, due to its simplifying assumptions, is computationally efficient, yet reliable in identifying the small subset of useful configurations for further detailed process evaluation. This two-tier approach allows expedient search of the configuration space containing hundreds to thousands of candidate configurations for a givenmore » application.« less

Minimum reflux calculation for multicomponent distillation in multi‐feed, multi‐product columns: Mathematical model

Journal Article Jiang, Zheyu ; Tawarmalani, Mohit ; Agrawal, Rakesh - AIChE Journal

Abstract Multi‐feed, multi‐product distillation columns are ubiquitous in multicomponent distillation systems. The minimum reflux ratio of a distillation column is directly related to its energy consumption and capital cost. Thus, it is a key parameter for distillation systems design, operation, and comparison. In this series, we present the first accurate shortcut based algorithmic method to determine the minimum reflux condition for any general multi‐feed, multi‐product (MFMP) distillation column separating any ideal multicomponent mixture. The classic McCabe‐Thiele or Underwood method is a special case of this general approach. Compared with existing techniques, this method does not involve any rigorous tray‐by‐tray calculation,more »« less

Global minimization of total exergy loss of multicomponent distillation configurations

Journal Article Jiang, Zheyu ; Chen, Zewei ; Huff, Joshua ; ... - AIChE Journal

Abstract The operating cost of a multicomponent distillation system comprises two major aspects: the overall heat duty requirement and the temperature levels at which the heat duties are generated and rejected. The second aspect, often measured by the thermodynamic efficiency of the distillation system, can be quantified by its total exergy loss. In this article, we introduce a global optimization framework for determining the minimum total exergy loss required to distill any ideal or near‐ideal multicomponent mixture using a sequence of columns. Desired configurations identified by this new framework tend to use milder‐temperature reboilers and condensers and are thus attractivemore »« less

A Simple Criterion for Feasibility of Heat Integration between Distillation Streams Based on Relative Volatilities

Journal Article Mathew, Tony Joseph ; Gooty, Radhakrishna Tumbalam ; Tawarmalani, Mohit ; ... - Industrial and Engineering Chemistry Research

In a multicomponent distillation configuration, there are numerous sources and sinks of heat, and a potential way to reduce the heat duty requirement is to perform heat integration. Unfortunately, an algorithmic search of the optimal heat integration opportunities is intractable when the required temperatures of intermediate streams are computed via complex models. Instead, in this work, we introduce pressure-scaled pseudo relative volatility, a new metric to compare stream temperatures. Here, we justify the use of pseudo relative volatility by proving that this variable is a monotonically increasing function of the liquid fraction in a saturated mixture stream. Using this metric,more »« less

Maximum fractionation by distillation of systems with constant relative volatilities

Journal Article Barolo, M ; Guarise, G B - Industrial and Engineering Chemistry Research; (United States)

This paper addresses the problem of shortcut simulation of a continuous distillation column. A computationally inexpensive approach is presented which considers the separation of a given feed in a column with an infinite number of stages in both the enriching and the stripping sections. The results so obtained represent the maximum fractionation that can be achieved for the given mixture at the given operating conditions. Reference is made to multicomponent systems with constant relative volatilities, and the classical Underwood equations are used. Examples are presented that show a good agreement with the results obtained in the case of a columnmore »« less
