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.

Self-heat recuperation technology for energy saving in chemical processes / Yasuki Kansha in Industrial & engineering chemistry research, Vol. 48 N° 16 (Août 2009)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 48 N° 16 (Août 2009) . - pp. 7682–7686 Titre : Self-heat recuperation technology for energy saving in chemical processes Type de document : texte imprimé Auteurs : Yasuki Kansha, Auteur ; Naoki Tsuru, Auteur ; Kazuyoshi Sato, Auteur Année de publication : 2009 Article en page(s) : pp. 7682–7686 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Self-heat recuperation technology Thermal processes Résumé : An innovative self-heat recuperation technology has been developed for heating and cooling thermal processes, in which not only latent heat but also sensible heat are circulated in a feed−effluent heat exchanger of the thermal process by compressing the effluent stream without any heat addition. Applying this technology to the thermal processes, the amount of energy required was determined using a commercial process simulation tool, PROII. The proposed self-heat recuperation technology, in which the heat of an effluent stream is recuperated and reused for feed stream heating by gas and/or vapor recompression, was found to drastically reduce the energy consumption.
