Synthesis of Water Networks with Water Loss and Gain via an Extended Pinch Analysis Technique

Xiao Feng and Chun Deng,     China University of Petroleum, Beijing, China


In this chapter, a new Process-based Graphical Approach (PGA) is presented for the simultaneous targeting and design of water networks. The PGA is extended from the Limiting Water Profile and conventional Water Pinch Analysis technique, which were developed for flowrate targeting of a water network. With the PGA procedure, in addition to locating the minimum freshwater and wastewater flowrate targets, the water network that corresponds to the minimum flowrate targets is also simultaneously identified. The revised Limiting Water Profile is introduced for the flowrate ...
