Energy analysis based on the simulation results showed that the primary energy consumption and CO2 emission in the proposed process can be decreased to 74% and 36% of that of the conventional heat recovery dryer, respectively. Moreover, exergy analysis was conducted to clarify exergy losses in the proposed drying process, and further energy-saving solutions were raised to minimize exergy loss based on exergy recuperation theory. The experimental results indicated that three times of the minimum fluidization velocity was a necessary condition for good fluidization. It was also confirmed that the proposed fluidized bed dryer for biomass drying achieves stable performance for more than 2 h in the experiments.

Exergy recuperative CO2 gas separation in post-combustion capture / Akira Kishimoto in Industrial & engineering chemistry research, Vol. 50 N° 17 (Septembre 2011)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 50 N° 17 (Septembre 2011) . - pp. 10128-10135 Titre : Exergy recuperative CO2 gas separation in post-combustion capture Type de document : texte imprimé Auteurs : Akira Kishimoto, Auteur ; Yasuki Kansha, Auteur ; Chihiro Fushimi, Auteur Année de publication : 2011 Article en page(s) : pp. 10128-10135 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Combustion Carbon dioxide Résumé : Exergy recuperation is applied to CO2 gas separation processes with chemical absorption for post-combustion capture. The heat of the exothermic absorption reaction in the absorber and the heat of steam condensation in the condenser of the stripper are recuperated and circulated to reuse for regeneration of solution and vaporization of water under CO2 stripping using exergy recuperation technology. We evaluated the amount of energy consumption of the exergy recuperative process in comparison with the conventional CO2 gas separation process by using a commercial process simulator (PRO/II, Invensys). The simulation results show that the energy consumption of the exergy recuperative CO2 gas separation process can be decreased to 30% of that of the conventional self-heat recovery process.
