Capital cost targets for mass exchange networks A special case: Water minimisation

Source composite curve for waste reduction

“…Eq. (8) implies that R and W are related by a constant, Δ. Therefore, minimization of W implies minimization of R as well.…”

“…Pinch analysis has been fruitfully used in analyzing heat exchanger networks [3], utility systems [5,6], mass exchanger networks [7][8][9][10], water networks [11], distillation column [12][13][14][15][16], production planning [17,18], etc. Pinch analysis recognizes the importance of setting targets before design.…”

On the use of systems technologies and a systematic approach for the synthesis and the design of future biorefineries

“…Such methods are plentiful on energy targeting (Gundersen, 1988;Briones and Kokossis, 1999a,b), water targeting (Wang and Smith, 1994a,b;Smith, 2005;Hallale and Fraser, 1998;Alva-Argaez et al, 1999;2007a,b;Gunaratnam et al, 2005), and mass-exchange networks (Halwagi, 1997(Halwagi, , 1990a(Halwagi, ,b, 2006(Halwagi, , 2008, but also in reactor and reaction engineering targeting (Halwagi and Srinivas, 1992;Marcoulaki and Kokossis, 1999;Kokossis, 1997, 1998;Kokossis and Floudas, 1990), simple and complex distillation Kokossis, 2001, 2002), solvent design (Papadopoulos and Linke, 2006a, b;Kazantzi et al, 2007, Kazantzi andHalwagi, 2005;Kokossis, 2000, 2001) and reaction-separation systems (Linke and Kokossis, 2003a,b, 2004Kokossis and Floudas, 1991). Instead, literature evidence indicates a predominant use of general flowsheeting technology for techno-economic and case-by-case analysis, using Aspen Plus for instance, as in the work of NREL on bioethanol production (Wooley et al, 1999) and that of Haas et al (2006) for biodiesel.…”

An Evaluation of Biological Approach for the Effluent Treatment of Paper Boards Industry - An Economic Perspective

“…In recent years various systematic design approaches to wastewater reuse across complex manufacturing operations have been developed [7][8][9][10][11]. Because economic benefits are undoubtedly a major driver for industry to implement wastewater reuse programs, recent research in this area has focused on the economic optimization of wastewater reuse systems [12][13][14][15].…”
