Heat exchanger network design of large-scale industrial site with layout inspired constraints

A novel graphical technique for Pinch Analysis applications: Energy Targets and grassroots design

“…This new technique divided the design problem into enthalpy intervals, determined by breaking points on hot and cold Composite Curves. Pouransari and Maréchal [10] developed a new method by considering the plant layout. This new method allowed selecting the closest matches geographically during the design stage.…”

Cost-Optimal Heat Exchanger Network Synthesis Based on a Flexible Cost Functions Framework

“…Furthermore, Newton's method is utilized for local parameter optimization [22]. Equation (18) shows the nomenclature in Newton's method for the variables (U…”

“…In addition, piping costs are considered. The required coordinates for the corresponding streams are taken from Pouransari and Maréchal [18]. They added arbitrary Cartesian coordinates to the 10SP1 problem stated above.…”

“…Liew et al [17] introduced an improved heat cascade algorithm considering pressure drop and heat loss for utility targeting in total site heat integration. Pouransari and Maréchal [18] took into account individual priority levels for different possible connections and Souza et al [19] included pressure drops in piping as well as in heat exchangers.…”

A grid-based facilities allocation approach with safety and optimal heat exchanger networks synthesis

“…Both layout and HEN demands piping and a well-known fact indicates that piping cost could be as high as 80 percent of delivered purchase equipment cost (Peters et al, 2003). In a recent publication, the geographical unit location has been incorporated into the HEN synthesis via weighting factors to account for the preference of a possible match between two streams (Pouransari and Maréchal, 2014). It has been claimed in that work that heat integration might be avoided between units in geographical distance to generate realistic networks.…”
