This work presents an energetic analysis of three butanol recovery processes from acetone-butanol-ethanol (ABE) fermentation broth. The processes were based on: 1) gas stripping, 2) liquid-liquid extraction, and 3) supercritical extraction. Material and energy balance simulations were carried out by commercial software Aspen Plus®. Processes were characterized in terms of energy efficiency and specific energy requirement. Operating conditions-e.g. gas stripping flow rate and solvent flow rate-were investigated and optimized with respect to the energy objective functions. © 2016, AIDIC Servizi S.r.l.

Abstract
This work presents an energetic analysis of three butanol recovery processes from acetone-butanol-ethanol (ABE) fermentation broth. The processes were based on: 1) gas stripping, 2) liquid-liquid extraction, and 3) supercritical extraction. Material and energy balance simulations were carried out by commercial software Aspen Plus®. Processes were characterized in terms of energy efficiency and specific energy requirement. Operating conditions-e.g. gas stripping flow rate and solvent flow rate-were investigated and optimized with respect to the energy objective functions. © 2016, AIDIC Servizi S.r.l.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
