Shell-and-tube heat exchangers are widely used in process industries due to their robustness and well-established design methods. Process engineers frequently need to specify these exchangers and perform calculations to confirm the appropriate sizing and heat transfer area. Insufficient understanding can lead to incorrect equipment selection, inability to meet process requirements, and safety risks. This course provides comprehensive knowledge of heat exchanger design, specification, and performance evaluation to ensure optimal operation.

Engineers and technical personnel across disciplines involved in the design, specification, and operation of shell-and-tube heat exchangers for chemical processes.
