A Design Procedure and Distillation Characteristics for a Self-Reflux Internal Heat-Integrated Distillation System with a Heat Pump.

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....

Simultaneous Design of Heat Integrated and Thermally Coupled Distillation Systems

Abstract In this work we present a methodology for synthesizing sequences of columns that combine both, the heat integrated and the thermally coupled distillation columns. As a consequence it is possible to design systems capturing simultaneously the advantages of these two approaches. A superstructure based on separation tasks rather in actual columns is proposed. This approach is more flexibl...

Multiple Steady-States in a Heat Integrated Distillation Column (HIDiC)

Selecting appropriate control variables for a heat-integrated distillation system with prefractionator

A heat-integrated prefractionator arrangement is studied for a ternary separation of a propane–butane–pentane mixture. These types of integrated prefractionator arrangements have large energy savings compared with the best of the direct or indirect sequence with no heat integration. However, a heat-integrated distillation system can be more difficult to control than a non-integrated arrangement...
