“…Each particle is formed by the follow variables: tube length, hot fluid allocation, position in the TEMA table (that automatically defines the shell diameter, tube bundle diameter, internal and external tube diameter, tube arrangement, tube pitch, number of tube passes and number of tubes). After the particle generation, the heat exchanger parameters and area are calculated, considering the Equations from the Ravagnani and Caballero (2007a) as well as Equations (155) to (160). This is done to all particles even they are not a problem solution.…”

“…The tube outlet and inlet diameters and the tube pitch are fixed. Table 12 presents the heat exchanger configuration of Shenoy (1995) and the designed equipment, by using the best solution obtained with the proposed MINLP model of Ravagnani and Caballero (2007a) and the PSO algorithm proposed by Ravagnani et al (2009). In Shenoy (1995 the standards of TEMA are not taken into account.…”

“…For example, the tube length used is 1.286 m and the minimum tube length recommended by TEMA is 8 ft or 2.438 m. As can be seen in Shenoy (1995) and Ravagnani and Caballero (2007a), respectively, as well as the number of tubes (102 vs. 194 and 368). The shell diameter is the same as presented in Ravagnani and Caballero (2007a), i.e., 0.438 m, as well as the tube length. Although with a higher tube length, the heat exchanger would have a smaller diameter.…”

“…So, more realistic values can be obtained if these coefficients are not estimated, but calculated during the design task. A few number of papers present shell and tube heat exchanger design including overall heat transfer coefficient calculations (Polley et al, 1990, Polley and Panjeh Shah, 1991, Jegede and Polley, 1992, and Panjeh Shah, 1992, Ravagnani, 1994, Ravagnani et al (2003, Mizutani et al, 2003, Serna and Jimenez, 2004, Ravagnani and Caballero, 2007a, and Ravagnani et al, 2009. In this chapter, the work of Ravagnani (1994) will be used as a base to the design of the shell and tube heat exchangers.…”

Simultaneous synthesis of heat exchanger networks with pressure recovery: Optimal integration between heat and work

2013

View full text Add to dashboard Cite

The optimal integration between heat and work may significantly reduce the energy demand and consequently the process cost. This paper introduces a new mathematical model for the simultaneous synthesis of heat exchanger networks (HENs) in which the pressure levels of the process streams can be adjusted to enhance the heat integration. A superstructure is proposed for the HEN design with pressure recovery, developed via generalized disjunctive programming (GDP) and mixed-integer nonlinear programming (MINLP) formulation. The process conditions (stream temperature and pressure) must be optimized. Furthermore, the approach allows for coupling of the turbines and compressors and selection of the turbines and valves to minimize the total annualized cost, which consists of the operational and capital expenses. The model is tested for its applicability in three case studies, including a cryogenic application. The results indicate that the energy integration reduces the quantity of utilities required, thus decreasing the overall cost.

Heat Exchanger Network (HEN) synthesis is an important field of study in process engineering. However, obtaining optimal HEN design is a complex task. When mathematically formulated, it may require sophisticated methods to achieve good solutions. The complexity increases even more for large-scale HEN. In this work, a hybrid meta-heuristic method is presented. A rather simple Simulated Annealing approach is used for the combinatorial level, while a strategy named rocket fireworks optimization is developed and applied to the continuous domain. An advantage over other approaches is that the algorithm was written in C11, which is free and faster when compared to many other languages. The developed method was able to provide the lowest costs solutions reported so far to six cases well studied in the literature. An important feature of the approach here proposed is that, differently from other approaches, it does not split HEN into smaller problems during the optimization.
