Two approaches are described, an analytical approach and a numerical approach. In the analytical approach, the KERN method is proposed. For the numerical process, Hysys software is used for design. Emphasis is placed on the sizing and design of a tube and shell type heat exchanger.exchanger, heat, tube, shell, simulation, design, KERN.
