Minimum reflux ratio and possibility of energy saving on a plate-to-plate heat-integrated distillation column.

Energy targeting and minimum energy distillation column sequences

The determination of distillation column configurations that consume the least total energy is studied. The novel contributions of the proposed designmethodology for finding globalminimum energy column sequences presented in this article include: (1) the definition of a total stripping line distance function for any sequence, (2) a robust energy targeting strategy that provides a continuously d...

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....

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

Assessment of the Effect of Feed Plate Location on Interactions for a Binary Distillation Column

The paper considers the effect of feed plate location on the interactions in a seven plate binary distillation column. The mathematical model of the distillation column is deduced based on the equations of mass and energy balances for each stage, detailed model for both reboiler and condenser, and heat transfer equations. The Dynamic Relative Magnitude Criterion, DRMC is used to assess the inte...
