Abstract:
In ths work, new multicomponent feasibility, column design and column sequencing tools are proposed. These tools are particularly useful in the synthesis of distillation columns and column sequences that separate azeotropic mixtures, where they provide accurate design parameters as well as good estimates of product compositions for use in commercial simulators. Recent work on ternary mixtures has led to the development of a new criterion for establishing staged column feasibility. This new criterion provides a necessary and sufficient condition for staged-column feasibility, and a column desig

Abstract:
A large number of distillation sequences can be generated to separate a multicomponent azeotropic mixture. However, there is no systematic and efficient method for synthesising promising sequences, which also consider recycle connections and flowrates. In this work, a systematic procedure is developed for synthesising economically promising distillation sequences separating multicomponent homogeneous azeotropic mixtures. The procedure uses spherically approximated distillation boundaries, a shortcut column design method, and allows recycle and sequence alternatives to be screened. Both feasibi

Abstract:
Distillation is the most widespread method for separating liquid mixtures. The separation of azeotropic mixtures requires a special distillation method. My aim was to improve the batch distillation separation of azeotropic mixtures. A new algorithm was presented for the determination of product sequences of batch distillation of multicomponent azeotropic mixtures. Non-conventional configurations were studied by simulation with emphasis on closed operation. The effects of off-cut recycle on a six-batch separation process of a waste solvent mixture were also investigated. Batch extractive distil

Abstract:
<p>Separation of azeotropic mixtures is of great industrial importance and distillation is the dominating unit operation for such separations. However, the presence of azeotropes and non-idealities in the phase behaviour of such mixtures complicates the separation. In the pharmaceutical and fine/specialty chemical industry, the small-scale production and the requirement for flexibility indicates batch distillation as the best suited process. Among, various techniques to enhance distillation, heterogeneous azeotropic (heteroazeotropic) distillation is a very powerful and widely used one. Thus,

Abstract:
The batch distillation of crude wood oil by direct liquefaction was studied; azeotropic distillations and some characterization were also performed. It was found that 26-33 percent of the crude wood oil could be distilled by simple batch vacuum distillations with pressures from 50-300 mm Hg. With the use of ethylene glycol and glycerol 29-85 percent more oil was distilled partly due to the azeotrope formed which allows the oil to boil at a reduced pressure. The water liberated and the polymerization which took place during the distillations were studied. It was found that fluid catalytic crack

First system considers a flowsheet for the separation of the IC5/methanol azeotropes that takes advantage of the heterogeneity of the azeotrope. Two stripping columns and a decanter are used. Second system is to study a heterogeneous azeotropic distillation column system for the separation of Propylene Glycol Monomethyl Ether (PM) and water using Isopropyl acetate (IPOAC) as entrainer.

Dynamic behavior for a heterogeneous azeotropic distillation column with various of controllers can be linked together using these modules. Both ethanol dehydration and SBA (secondary butyl alcohol) dehydration processes including steady-state study have been explored on basis of these modules. It was also found that the calculations of VLE/VLLE using rigorous thermodynamic algorithm is often the bottleneck of executing speed

The pressure swing distillation(PSD) is an effective separation of binary azeotropic mixtures, and it has the advantages of simplicity, low energy and low cost. In this study we focused on two parts, the first part is to determine the azeotropic compositions and temperatures by use of the Wilson equation. The second part is to explore the applicability of PSD and locate the best operating conditions. The study shows various compositions corresponding to the pressure 1atm、2at

碩士<br>國立成功大學<br>化學工程學系碩博士班<br>96<br>By addressing both flow sheet generation and scheduling issues, a sequential design method has been developed in this work for the batch azeotropic distillation systems. The proposed strategies can be applied in two stages. Firstly, an Integer Programming (IP) is solved to produce the optimal flow sheet (or state-task network). A Mixed Integer Linear Programming Model (MILP) is then constructed accordingly for generating the optimal short-term schedule. On the other hand, a Mixed Integer Non-Linear Programming (MINLP) is also constructed for generating optim

Abstract:
While it has been known for about 130 years that azeotropes are influenced by changing pressure, this fact has never been fully exploited. In this dissertation it is shown how pressure effects can be used to advantage or can foil attempts to distill homogeneous azeotropic mixtures and how an analysis of the fixed points of the distillation model leads to new important insights into extractive distillations. As the pressure varies, not only the composition but also the number of azeotropes can change. A change in the number of azeotropes corresponds to a transcritical bifurcation. A bifurcation

碩士<br>國立臺灣大學<br>化學工程學研究所<br>105<br>Triple column pressure swing distillation (TCPSD) can be a promising method to separate azeotropic ternary mixtures. In order to adopt this configuration, a pre-requisite is that the distillation boundaries move apparently under different operating pressures, and this can be checked through the residue curve map (RCM). In this thesis, a rigorous and extensive study on TCPSD is performed, with several separation system containing different amount of azeotropes as demonstration. All of the simulation work is implemented in Aspen Plus v8.4. The first separation

Abstract:
Ethanol-water forms homogeneous minimum boiling azeotrope and it has most common occurrence in many industrial processes. There are various techniques exist to separate azeotropic compositions. In this work we studied the basic features of azeotropic distillation using Aspen plus simulation. Since entrainers are indispensable in separating constant boiling mixtures, in this work, performances of three different entrainers were studied viz. benzene, n-pentane and cyclohexane. The effect of various process variables viz. reflux-ratio and distillate rate on the purity of the final products was st

These conditions where internal recycle is beneficial are determined by studying the generalized dimensionless equations. The result is a general framework for understanding internal recycle.
