A conceptual methodology for simultaneous optimization of water and heat with non-isothermal mixing

Yanlong Hou, Wanni Xie, Zhenya Duan, Jingtao Wang

Frontiers of Chemical Science and Engineering 2017, Volume 11, Issue 2,   Pages 154-165 doi: 10.1007/s11705-016-1593-z

Abstract: A new conceptual methodology is proposed to simultaneously integrate water allocation and energy networksIn the first step, the water allocation network (WAN), which could achieve the targets of saving waterand energy, is obtained by taking account the temperature factor into the design procedure.The optimized targets of both freshwater and energy are reached at this step which ensures this approachThe thus obtained WAHEN can achieve three optimization targets (minimization of water, energy and the
