“…The basic concepts for the mass integration strategies can be found in the literature (see for example the books by El-Halwagi (El-Halwagi, 2006, 1997). One of the most interesting applications for the mass integration strategies is the minimization for the fresh water consumption through the use of recycle and reuse networks, and considering regeneration units, several techniques have been reported to provide conceptual and graphical approaches to solve this problem (see for example references (Wang and Smith, 1994;Gomes et al, 2007;El-Halwagi and Spriggs, 1996;Sorin and Bedard, 1999;Kuo and Smith, 1998;Polley and Polley, 2000;Hallale, 2002;El-Halwagi et al, 2003;Dakwala et al, 2009;Kumaraprasad & Muthukumar, 2009;Foo et al, 2005;Saw et al, in press;Chen and Lee, 2010;Tan et al, 2010;Manan et al, 2009)), and others methodologies have used mathematical approaches for the water integration (see (Takama et al, 1980;Doyle and Smith, 1997;AlvaArgaez et al, 1998;Galan and Grossmann, 1998;Huang et al, 1999;Benko et al, 2000;Savelski and Bagajewicz, 2000;Tan et al, 2008;Hernandez-Suarez et al, 2004;Gabriel and El-Halwagi, 2005;Karuppiah and Grossmann, 2006;Gunaratnam et al, 2005;Bai et al, 2010;Feng et al, 2008;Handani et al, 2010;Tokos and Pintaric, 2009;Lavric et al, 2005;Oliver et al, 2008;…”
