“…Then, Genetic Algorithm is used so as to find the optimal heat distribution along the HIDiC while the fitness function is set to be the total annual cost (TAC). The best HIDiC configuration obtained is compared with the reported solutions in a previous work for the same examined case study (Suphanit, 2010;Shahandeh et al, 2014). In this paper, the design-optimization strategy is performed by using the Excel-ProSimPlus interface.…”

Distillation is the most applied separation technology. However, its major drawback is the low thermodynamic efficiency (typically around 10%). In response to environmental issues that concern energy consumption of distillation columns, HIDiC (heat integrated distillation column) is expected to have a large impact on energy saving. The aim of this study is to optimize the HIDiC sensitive parameters so as to minimize the Total Annual Cost (TAC). For this, a HIDiC simulation model is developed by using commercial software ProSimPlus. GA (Genetic Algorithm) is used to find the optimal HIDiC configuration where multivariable are optimized without initialization. Binary (Benzene/Toluene) separation case is examined. As a result, 7.4 % and 13.9 % TAC reductions are realized in comparison with the reported solutions in previous works.

Vapor recompression and bottom flashing are among the developed technologies for enhancing energy efficiency of distillation processes. In this paper, a novel configuration of bottom flashing system is proposed for enhancing energy efficiency of dual columns such as direct distillation sequences. The system is designed to operate between two distillation columns. The proposed system engages two separate distillation columns, both of which can be wide boiling systems. The system incorporates two interacting bottom flashing systems that engage the two distillation columns through heat transfer from the top product of the second column to the bottom product of the first column which in turn results in elimination/reduction of utility requirements of condenser of the second column along with reboiler of the first column. Based on the results of this study, compared to conventional direct sequence distillation, 40.3% reduction in energy requirements and 20.7% reduction total annual costs of the process can be obtained through application of the proposed system.

Distillation columns with side draws are widely used in the process industry to refine crude methanol into high‐purity methanol. Historically, industrial methanol manufacturers have concentrated on meeting strict product specifications, while methanol yield and reboiler duty optimisation has often been neglected. In this work, a steady‐state model of an industrial high‐purity multi‐component methanol distillation column was developed using a commercial process simulator. To achieve higher recovery at optimal reboiler duty, the side draw location and side draw mass flow rates were identified as two important factors. It was determined that a combination of lowering the side draw location while reducing the side draw mass flow rate will lead to the most optimal outcome. A design of experiment was also carried out to evaluate the stability of the column at recovery rates of 97.7% (current recovery) and 99.5% (proposed high recovery). Disturbances in the feed stream were identified as having the greatest effect, while the product purity was observed to become more sensitive towards all disturbances when operating at an enhanced recovery. © 2016 Curtin University of Technology and John Wiley & Sons, Ltd.
