Minimum and Total Reflux in Ideal Heat Integrated Distillation Column(HIDiC).

Total Reflux Operation of Multivessel Batch Distillation

I N T R O D U C T I O N Although batch distillation generally is less energy efficient than continuous distillation, it has leceived increased attention in the last few years because of its simplicity of operation, flexibility and lower capital cost. For many years academic research on batch distillation was focused primarily on optimizing the reflux policy. However, in most cases the differenc...

Shortcut methods for complex distillation columns : part 1 -- Minimum reflux

Shortcut Methods for Complex Distillation Columns: Part 1 -Minimum Reflux This two-part paper presents in detail the theory for calculating via shortcut methods the minimum reflux conditions and the number of stages and feed tray location for ordinary and thermally coupled columns. Nonadjacent key components are permitted. In this paper, part 1, the approximations made to estimate minimum reflu...

Internally Heat-integrated Distillation Columns: a Review

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...

The Design and Optimization of Distillation Column with Heat and Power Integrated Systems

Based on two integration steps, an optimization framework is proposed in this work for the synthesis and design of complex distillation sequence. The first step is to employ heat integration in sequence and reduce the heat consumption and total annual cost of the process. The second one is to increase the exergetic efficiency of sequence by generating power in implemented expanders in sequence....
