VIEIRA, A. J. M.; PESSOA, F. L. P.  and  QUEIROZ, E. M.. Fluid dynamical considerations on heat exchanger networks. Braz. J. Chem. Eng. [online]. 2000, vol.17, n.1, pp.19-27. ISSN 1678-4383.

The synthesis and analysis of heat exchanger networks are issues of great industrial interest due to the possibilities of decreasing plant costs, through the reduction of the utilities consumption and/or the number of equipments, in a grassroot design or retrofitting an existent network. The present paper explores a new design algorithm based on the Total Annual Cost (TAC) optimization for a thermal equipment, with mean tubeside and shellside flow velocities constraints, studying also the influence of pumping cost in the network’s final cost.

Keywords : heat exchanger network; pressure drop optimization; heat exchanger design.
