Abstract Distillation is widely used for separating liquid mixtures, but its high heating demand poses challenges achieving net‐zero emissions. This study presents an innovative approach to electrifying distillation load adaptability and flexible operation, aligning with dynamic electricity markets driven by renewables. The integrates flash vapor circulation thermal storage into the optimize power usage capitalizes on economic opportunities from load‐flexible operation in response fluctuating pricing. A methanol/water case study, using two typical pricing scenarios, demonstrates that proposed more economically efficient than mechanical recompression distillation, especially lowering operational costs when latter operates under fixed However, compressor capital significantly impact overall costs, sensitivity analysis examining different cost models. can be applied general allowing integration sector programs, while enhancing flexibility, decarbonization, efficiency.

The benzene–toluene–xylene (BTX) system represents an energy-intensive petrochemical process with various industrial applications. Global climate changes have forced modern industry to act toward environmental safety, which requires technological changes. Thus, the divided wall column (DWC) a significant advancement in multicomponent mixture separation. To assess impact of conventional BTX and its intensification proposal based on DWC technology, it is necessary integrate eco-efficiency approach that jointly analyzes economic variables influencing system, such as water consumption, CO2 emissions, utility costs. An auxiliary plant was also considered for more realistic results terms energy identified lack many research studies performed overall sustainability analysis. showed scheme 37.5% eco-efficient than counterpart, mainly due 15.6% 30.3% savings respectively, provided 15.5% 16.7% reduction emissions costs, respectively. In addition, all other safety indicators waste algorithm (WAR) were reduced by approximately 16%. proved be convenient technology attractiveness friendliness.

Abstract Electrification of distillation processes through discretely heat integrated columns (D‐HIDiC) is an effective approach to enhance energy efficiency and lower carbon emissions. For separating systems with high temperature lift, multi‐stage compression inter‐stage cooling are necessary link the high‐pressure rectifier low‐pressure stripper. Traditionally, recovery employs pumparound loops, but this study introduces liquid injection as a more efficient innovative alternative. Simulation results using methanol/water separation indicate that reduces both reboiler duty power, achieving up 50% primary savings compared conventional columns. Unlike continuous exchange in HIDiC (C‐HIDiC), D‐HIDiC simplifies integration, avoiding complex hardware penalties. Comparative analysis across multiple configurations, including SuperHIDiC, confirms potential fully electrify distillation, eliminate steam utility, significantly support sustainable industrial operations.
