Targeting for conventional and property-based water network with multiple resources / Chun Deng 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. 3722–3737 Titre : Targeting for conventional and property-based water network with multiple resources Type de document : texte imprimé Auteurs : Chun Deng, Auteur ; Xiao Feng, Auteur Année de publication : 2011 Article en page(s) : pp. 3722–3737 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Water  network Résumé : Water scarcity and stringent emission legislation have been motivating process industries to emphasize water conservation. Pinch analysis has been accepted as one of the powerful approaches to locate targets of wastewater minimization. In this paper, the improve problem table (IPT) is presented to target conventional and property-based water networks with multiple resources on the basis of the composite table algorithm (CTA) (Agrawal, V.; Shenoy, U. V. Unified conceptual approach to targeting and design of water and hydrogen networks. AIChE J.2006, 52, 1071−1082). The corresponding limiting composite curve and water supply line are plotted to facilitate the analyzing and understanding of basic physical insights. The minimum operating cost subject to availability of the water resources is also addressed. In addition, two strategies are proposed to handle flow rate constraints for certain resources, and the corresponding wastewater stream identification techniques are introduced successively. To illustrate the applicability of IPT, two conventional so-called concentration-based water networks with different scenarios, i.e., direct reuse/recycle and regeneration reuse/recycle, are synthesized. Moreover, the targets for a property-based water network with a pretreatment system are determined via the proposed IPT.
