There are several software design and rating packages available, including AspenBJAC, HTFS and CC-THERM, which enable the designer to study the effects of the many interacting design parameters and achieve an optimum thermal design. Setting upper and lower design limits on shell diameter, baffle cut and baffle spacing. Specification of shell side parameters materials, baffle cut, baffle spacing and clearances. Setting upper and lower design limits on tube length. Specification of tube parameters - size, layout, pitch and material. Selection of heat exchanger TEMA layout and number of passes. Selection of heat transfer models and fouling coefficients for shell side and tube side.ġ. Setting shell side and tube side velocity limits. Setting shell side and tube side pressure drop design limits. Selection of stream temperature specifications. Process fluid assignments to shell side or tube side. The optimum thermal design of a shell and tube heat exchanger involves the consideration of many interacting design parameters which can be summarised as follows:ġ. The author claims no originality but hopes that the format and contents will provide a comprehensive introduction to the subject and enable the reader to achieve rapid and meaningful results. The objective of this paper is to provide a concise review of the key issues involved in their thermal design without having to refer to the extensive literature available on this topic. Shell and tube heat exchangers are used extensively throughout the process industry and as such a basic understanding of their design, construction and performance is important to the practising engineer.
