    Abstract

    This paper presents a novel optimization method for heat exchanger network (HEN) retrofit including stream splitting. A simple mixed integer linear programming (MILP) model and two iterative loops have been developed to effectively deal with the nonlinear computational difficulties associated with logarithmic mean temperature difference (LMTD) and retrofit costs for HEN retrofit problems. In case study, comparison with the existing methods illustrates the validity of the proposed approach. © 2012 Elsevier B.V.
