Optimization of power - intensive energy systems with carbon capture / Xuesong Zheng in Industrial & engineering chemistry research, Vol. 50 N° 19 (Octobre 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 19 (Octobre 2011) . - pp. 11201–11225 Titre : Optimization of power - intensive energy systems with carbon capture Type de document : texte imprimé Auteurs : Xuesong Zheng, Auteur ; Jin-Kuk Kim, Auteur Année de publication : 2011 Article en page(s) : pp. 11201–11225 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Optimization  Energy  Systems Résumé : A systematic methodology for the synthesis of power systems has been developed, which explores the interactions among the equipment as well as the processes in power and utility systems. Also, the optimization is able to study the integration of CO2 capture processes with power systems for minimizing site-wide fuel consumption. Typical operating conditions for precombustion as well as postcombustion CO2 capture have been applied to estimate energy demand within the CO2 capture process. The power system is designed not only to meet the electricity and shaft power demand from the background process but also to satisfy the additional energy requirement incurred by CO2 removal. With the energy integration for the overall systems, the fuel consumption could be reduced, and operating cost, minimized. A case study is presented to demonstrate the usefulness and effectiveness of the proposed methodology for the design of energy and power systems in liquid natural gas (LNG) plants, under a carbon-constrained business environment.

Water allocation network design concerning process disturbance / Xiao Feng in Industrial & engineering chemistry research, Vol. 50 N° 7 (Avril 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 7 (Avril 2011) . - pp. 3675–3685 Titre : Water allocation network design concerning process disturbance Type de document : texte imprimé Auteurs : Xiao Feng, Auteur ; Renjie Shen, Auteur ; Xuesong Zheng, Auteur Année de publication : 2011 Article en page(s) : pp. 3675–3685 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Water  allocation  network Résumé : Water system integration can effectively reduce freshwater consumption and minimize wastewater discharge of a water-using system, but integration makes the resultant water network structurally more integrated among process units. Therefore, to design a flexible water allocation network that is easy to control becomes highly desirable. In this Article, a methodology is presented for water allocation network design with process disturbance taken into account. For a new design, the synthesized network structure can guarantee that the water system consumes minimum freshwater under both normal and disturbance conditions and with minimum number of control streams under disturbance. At the same time, the information needed to adjust flow rate under disturbance will be obtained. For an existing water system, an adjustment scheme under disturbance with minimum freshwater consumption for the existing structure will be obtained. The water network designed by the new methodology has the feature of minimum freshwater consumption and high flexibility under disturbance. Some case studies are used to demonstrate the method.
