Design and Rating of Shell and Tube Heat Exchangers PAGE 3 OF 30 MNL 032A Issued 29 August 08, Prepared by J.E.Edwards of P & I Design Ltd, Teesside, UK www.pidesign.co.uk 1. 0 Introduction 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. 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. 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 optimum thermal design of a shell and tube heat exchanger involves the consideration of many interacting design parameters which can be summarised as follows: Process 1. Process fluid assignments to shell side or tube side. 2. Selection of stream temperature specifications. 3. Setting shell side and tube side pressure drop design limits. 4. Setting shell side and tube side velocity limits. 5. Selection of heat transfer models and fouling coefficients for shell side and tube side. Mechanical 1. Selection of heat exchanger TEMA layout and number of passes.
