Lee J.-Y.Chen C.-L.Lin C.-Y.2019-05-212019-05-21201308885885https://scholars.lib.ntu.edu.tw/handle/123456789/409647This paper presents a mathematical model for the synthesis of water networks for systems consisting of process units of different operation modes, namely, truly batch, semicontinuous, and continuous units. By treating a continuous process as a special case of a semicontinuous process, the original problem becomes to synthesize a batch water network comprised of truly batch and semicontinuous units operated cyclically with a fixed schedule. The model is formulated as a mixed-integer nonlinear program based on a unit-tank superstructure including all possible network interconnections. Three modified literature examples are used to illustrate the proposed approach, with both in-plant and interplant water integration analyzed. ? 2013 American Chemical Society.journal article10.1021/ie302521v2-s2.0-84878622880https://www.scopus.com/inward/record.uri?eid=2-s2.0-84878622880&doi=10.1021%2fie302521v&partnerID=40&md5=0063cee5e6b2f5bc287220ebd297b86c
