Journal ArticleDOI
Improving the economy and energy efficiency of separating water/acetonitrile/isopropanol mixture via triple-column pressure-swing distillation with heat-pump technology
TL;DR: In this paper, the authors investigated two pressure swing distillation (PSD) processes with different separation order where the W-A-I separation sequence has a better performance in economy, energy consumption and environment.
Journal ArticleDOI
Energy-efficient extractive distillation combined with heat-integrated and intermediate reboilers for separating acetonitrile/isopropanol/water mixture
TL;DR: In this paper, a triple-column extractive distillation is investigated for the separation of acetonitrile/isopropanol/water mixture with ethylene glycol (EG) as entrainer.
Journal ArticleDOI
Novel methodology for determining the optimal vapor recompressed assisted distillation process based on economic and energy efficiency
TL;DR: A systematic method is designed to decide the optimal vapor recompressed heat pump assisted distillation (VRC) scheme by comparing the heat contributed by overhead vapor (ΔH0) and the heat required of reboiler (QR).
Journal ArticleDOI
Performance Enhancement of Heat Pump with Preheater-Assisted Pressure-Swing Distillation Process
TL;DR: In this article, a preheater is added before the compressor based on the dry fluid property of the isobutanol/isobutyl acetate mixture, and the optimal preheated temperature of the overhead vapor stream may further improve the performance of the heat pump-assisted PSD process.
Journal ArticleDOI
Investigation about energy-saving for the isobutyl acetate synthesis in a reactive divided-wall column via vapor recompression heat pump
TL;DR: In this article, the design that integrated vapor recompression heat pump into reactive divided-wall column (RDWC-HP) is proposed for the synthesis of isobutyl acetate.
