Interfactory and intrafactory water network system to remodel a conventional industrial park to a green eco-industrial park / Seong-Rin Lim in Industrial & engineering chemistry research, Vol. 49 N° 3 (Fevrier 2010)

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 3 (Fevrier 2010) . - pp. 1351–1358 Titre : Interfactory and intrafactory water network system to remodel a conventional industrial park to a green eco-industrial park Type de document : texte imprimé Auteurs : Seong-Rin Lim, Auteur ; Jong Moon Park, Auteur Année de publication : 2010 Article en page(s) : pp. 1351–1358 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Interfactory--Intrafactory--Water  Network  System--Remodel--Conventional--Industrial  Park--Green  Eco-industrial  Park Résumé : Water network synthesis is to optimize a water supply system by connecting water sources to sinks in order to maximize water reuse. This synthesis has been applied within a factory to reduce freshwater consumption. This study illustrates (i) the synthesis and design of an interfactory and intrafactory water network system for an eco-industrial park (EIPWNS) utilizing more opportunities for water reuse within an industrial park, and (ii) an environmental and economic feasibility study to demonstrate benefits from industrial symbiosis. An EIPWNS is synthesized, designed, and compared to a conventional water system (CWS). The feasibility study using life cycle assessment and life cycle costing shows that the total environmental impacts of the EIPWNS are 7.5% to 16.0% less than those of the CWS, and the life cycle cost of the EIPWNS is 15.6% less. Therefore, the EIPWNS can be employed in remodeling a conventional industrial park to an eco-industrial park. This study provides a good example for disseminating EIPWNSs.

Life cycle cost minimization of a total wastewater treatment network system / Seong-Rin Lim in Industrial & engineering chemistry research, Vol. 48 N° 6 (Mars 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 6 (Mars 2009) . - pp. 2965–2971 Titre : Life cycle cost minimization of a total wastewater treatment network system Type de document : texte imprimé Auteurs : Seong-Rin Lim, Auteur ; Haewoo Lee, Auteur ; Jong Moon Park, Auteur Année de publication : 2009 Article en page(s) : pp. 2965–2971 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Wastewater  treatment  plants  Wastewater  treatment  network  system  Life  cycle  cost  Superstructure  mode Résumé : Distributed wastewater treatment plants (WTPs) have been synthesized to reduce costs associated with wastewater treatment. This study developed a mathematical optimization model to synthesize existing distributed and terminal WTPs into an economical total wastewater treatment network system (TWTNS) from the perspective of life cycle cost (LCC). The objective function was formulated from the principal cost contributors in the construction, operations and maintenance, and disposal stages. The mass balances were formulated on the basis of the superstructure model, and the constraints were formulated to reflect real situations. A case study compared the LCC-minimized TWTNS (LNS) generated with this model to a conventional wastewater treatment system (CWTS) operated in a plant and to the TWTNS (FNS) generated by minimizing a total flowrate of wastewater treated in distributed WTPs. The LCC of the LNS was 12% less than that of the CWTS and was 27% less than that of the FNS, which validated the effectiveness of the model. This model can be used to practically retrofit existing WTPs.
