Ethanol is largely used as a solvent in the synthesis of varnishes and perfumes. It is also used as a preservative for biological products, fuel, and gasoline additives. Anethanol-water mixture, normally obtained by fractional distillation</span...
the synthesis of heat integrated multi-component distillation systems is complex due to its huge search space for structural combination and optimization computation. to provide a systematic approach and tools for the synthesis design of distillation systems, a new method for modeling heat integrated columns is presented, and the operating cost objective function is minimized by improved harmon...

This work presents a reactive distillation column for the catalytic disproportionation of trichlorosilane to silane which includes three consecutive reversible reactions. This reaction system is however characterized by a large distinction in the boiling points of the components, which make the reactive distillation extremely favored. Nevertheless, the normal reactive distillation column posses...
Internally heat integrated distillation column has received a great attention lately because of its ultimate potential for energy savings. Typical conceptual design of such columns is based on constant heat transfer duties along the column stages. This paper introduces more effective approach to conceptual design of heat integrated distillation columns based on constant available heat transfer ...
The heat-integrated distillation column to be addressed in this paper is a special distillation column that involves internal heat integration between the whole rectifying and the whole stripping sections. An overview of the research on this process is presented in this work. It covers from the thermodynamic development and evaluations to the practical design and operation investigations for th...
An internally heat integrated distillation column, HIDiC, offers the maximum energy saving potential for difficult and energy intensive separations, such as propylenepropane and the like, which are carried out in tray columns. A novel type of HIDiC was developed by TUDelft, namely a concentric distillation column in which a low pressure annular stripping section is configured around a high pres...
A multi-effect distillation where the condenser of a high pressure column is integrated with the reboiler of a low pressure column has been studied. The method of selfoptimizing control has been used to provide a systematic procedure for the selection of controlled variables, based on steady-state economics. The system has 10 degrees of freedom at steady state. The heat integrated distillation ...
Reactive distillation has received intense attention due to the well known benefits of integrating distillation with reaction in a single unit. While there are procedures available for the synthesis of non-reactive columns and of reaction-separation systems, the design of reactive distillation columns is still a challenge. This work presents a new synthesis and design methodology for reactive d...
