Design methodology for multistream plate-fin heat exchangers in heat exchanger networks

A newly developed methodology for the design of multistream plate-fin heat exchangers in the optimization of heat exchanger networks is described in d etail. The designed heat exchanger consists of several block sections with intermediate entry and exit points along its length, and these sections are determined by, the composite curves in the Pinch technology. The requireme nts of heat transfer and pressure drop are fulfilled through proper surface selection. The methodology was applied to an industrial case study, and th e detailed design parameters are given. The example confirms the validity o f the suggested methodology.
