“…In this work, the Bell−Delaware method 5 has been used to improve the reliability of such predictions. The Bell−Delaware model provides a detailed and a fairly reliable description for the flow pattern of the shell side of heat exchangers, and has been recently used to incorporate such details on the optimization of individual units and in the optimal design of integrated heat exchanger networks. − In the formulation presented in this work, the equations of the Bell−Delaware method have been transformed into compact expressions, with a similar mathematical form as those based on the Kern correlations. Thus, the proposed method has the advantage of offering a more realistic picture of the actual shell-side flow pattern, with little added complexity.…”

This paper presents an improved methodology for generating feasible regions for shell-and-tube exchanger design, taking into account geometric and operational constraints. The approach is based on the Bell-Delaware method to describe the shell-side flow with no simplification; this approach, therefore, can incorporate the entire range of geometric parameters of practical interest. Compact analytical equations are derived from the rigorous Bell-Delaware method for the shell-side heat transfer coefficient and pressure drop. These equations aid significantly in the solution of the design problem. The solution involves a nested approach where the compact equation parameters are treated as iteration variables; a simplified heat exchanger model is solved in an inner loop, and the exchanger parameters are updated in an outer loop. Compared to a previous work, which uses the approximate Kern method to describe the shell-side flow, the present one provides a better accuracy for the thermal design of shell-and-tube heat exchangers with single-phase fluids. One example is presented to show the application of the proposed method. The alternative use of proprietary design software is also illustrated.

“…Other studies examined different optimization methods involving the design of the HEs of the HEN, such as Ravagnani et al, 12,13 Polley, 14 Markowski, 15 and Roque. 16 However, the number of design variables for these exchangers were limited. Biyanto et al 17 studied HEN retrofit, which was applied to maximize heat recovery without changing the area of heat transfer or adding new HE and the arrangement of HE in HEN.…”

Summary The optimization of the total annual cost in heat exchanger networks has been one of the overarching goals when synthesizing these networks. Several methodologies and techniques have been developed to achieve optimal costs in mixed material heat exchanger networks. This paper demonstrates the application of two decomposition methodologies (total decomposition and partial decomposition) for typical cost rules. The objective function was defined as the optimization and minimization of the total annual cost in mixed materials heat exchanger network. Three optimization algorithms, hybrid genetic‐particle swarm optimization (GA‐PSO), shuffled frog leaping algorithm (SFLA) techniques, and ant colony optimization (ACO), were used to further optimize the total cost in mixed materials heat exchanger network. The results indicate that the total annual cost in partial decomposition method was smaller than that in full integration method and total decomposition method. The reduction of the total annual cost was about 27% for GA‐PSO algorithm, 24% for SFLA and 10% for ACO relative to the results reported in this work. In partial decomposition method, at least one mixed material of heat exchanger was used to reduce the hot and cold utility for decreasing the total annual cost. Partial decomposition method resulted in the highest reduction of the total annual cost compared with other methods. Percentage of difference of the total annual cost were 0.36%, 1.92%, and 5.05% for full integration, total decomposition, and partial decomposition methods, respectively, in comparison with the previous studies. Results have been compared with the results of other studies to demonstrate the accuracy of the applied algorithms.

Pressure drop and fouling are important issues in heat exchanger network synthesis, which are usually neglected. Heat exchangers were designed in detail during the heat exchanger network synthesis, and pressure drop and fouling effects were taken into account. Pinch analysis combined with exergoeconomic analysis was used for determining optimal minimum approach temperature (DT min ) for heat exchanger network synthesis. Exergy consumption of heat transfer in HENs was calculated using a subsection integral on balanced composite curves. The heat transfer coefficients of all heat exchangers in the network were calculated iteratively to meet the requirements of optimal area and allowable pressure drops. The proposed method was applied to an industrial case. Numerical results indicate the importance of the detailed design of heat exchangers in HENs synthesis.
