Economic and Environmental Evaluation of Heat-Integrated Pressure-Swing Distillation by Multiobjective Optimization

Abstract: A systematic procedure is proposed for the design of a pressure-swing distillation (PSD) process for a ternary mixture. This procedure involves thermodynamic insight, global optimization, and heat integration. The aim of thermodynamic insight is to analyze the process feasibility and find all of the possible separation sequences via residue curve maps and the distillation boundaries. The global optimization for a total of 16 variables in three columns is conducted by multiobjective genetic algorithm (MOGA) wit… Show more

“…Numerous scholars have conducted extensive research to explore the feasibility of heat-integrated distillation energy-saving technology. Much of this research focuses on the conceptual design of heat-integrated distillation columns in different scenarios, such as standard forms of heat-integrated distillation columns [6][7][8][9], heat-integrated pressure-swing columns [10][11][12], heat-integrated extractive distillation columns [13][14][15][16], heat-integrated air-separation columns [17][18][19][20], and heat-integrated reactive distillation columns [21][22][23][24]. Most of the works are primarily implemented through specific process simulation software.…”

“…Among numerous distillation energy-saving technologies, heat-integrated distillation technology has garnered extensive attention due to its significant potential for energy savings [11][12][13][14]. In heat-integrated distillation technology, the rectifying section and the Processes 2023, 11, 2918 2 of 18 stripping section are two separate columns, referred to as the rectifying column and the stripping tower, respectively [15][16][17][18][19]. These columns are connected by a compressor and a throttle valve to regulate the pressure between them.…”

“…Therefore, a multiobjective optimization algorithm that can identify the tradeoffs between these competing criteria must be used in order to develop chemical processes automatically. Single-objective optimization is not enough to achieve this [350].…”
