Abstract

Due to fouling in the heat-transfer units, the target temperatures of process streams in a heat exchanger network (HEN) may not always be achievable after a long period of operation. To address this practical issue, the conventional cost-optimal HEN design must be modified to accommodate online cleaning operations via proper allocation of area margins, bypasses, spares and auxiliary heaters/coolers. A solvable MINLP model has been developed in this work to simultaneously generate such design refinements and also the corresponding spare-supported cleaning schedules. The optimization results of one example are presented to demonstrate the feasibility of this approach.
