In this article, stream flow effectivness is based on hydraulic network studied in the shell-side of a shell and tube heat exchange as a case study. For an appropriate heat exchangers rating design to meet a specified duty, it's better to consider each stream flow separately. Using the hydraulic network principals, a set of the correlations for calculating different stream flow rates in the cro...

The following paper presents a mathematical formulation for the synthesis of heat exchanger networks (HEN’s), taking into account different types of heat exchangers (HE’s) and several conditions of operation. The model is developed using a disjunctive formulation into a preexistent multiperiod model. The Multiperiod-Disjunctive-MINLP was tested in an academic example comparing the results with ...

A comprehensive cost correlation analysis was conducted based on available correlations, and new equipment models were proposed QUE$TOR modeling. Cost correlations for various types of such as pumps, compressors, heat exchangers, air coolers, pressure vessels generated the basis extracted data. The derived robust multivariable regression with aim minimizing residuals by using genetic algorithm....
