Following this step-by-step approach will ensure that the heat exchanger will perform as required when finally fabricated
Shell-and-tube heat exchangers are among the most commonly used equipment in the chemical process industries (CPI), especially in petroleum refineries and chemical manufacturing facilities. The design cycle of a heat exchanger starts with the process engineer. However, to ensure a smooth fabrication, startup and operation, the cycle further goes through a mechanical design stage followed by detailed design by the fabrication vendor. The final geometry of the heat exchanger released for fabrication should meet both the process as well as the mechanical requirements.
The design of a shell-and-tube heat exchanger involves a close interaction among three parties: the process engineer, the mechanical engineer and the fabrication vendor. The process engineer and the mechanical engineer belong to the engineering company that carries out the detailed engineering design. The third-party is the fabrication vendor. The success of the design depends on how effectively all three parties have coordinated in the course of the design cycle of this equipment.
