A Shortcut Design for Kaibel Columns Based on Minimum Energy Diagrams

Abstract

In this paper, a shortcut procedure is proposed to design a 4-product dividing-wall column. It is based on the information derived from V min diagram. This has the advantage of having more meaningful guesses for energy requirements and impurity flows in the column. An example is used for illustration.

Optimization of a divided wall column for the separation of C4-C6 normal paraffin mixture using Box-Behnken design

“…A number of researchers have reported on the design, optimization and control of a DWC using va-rious optimization techniques and column configuretions [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. The design and optimization techniques were diverse.…”

Design of dividing wall columns for butanol recovery in a thermochemical biomass to butanol process

“…The middle section (C2x) of the product column in the Kaibel column performs the sharp B/C split [51]. However, as this has already been performed in the prefractionator, the number of trays in this section is computed as the minimum number of trays using the Fenske equation.…”
