Good understanding of the underlying principles of exchanger.

Capability to Diagnose for Feasibility & Viability design

Classification of S&T HE according to construction and criticality of service.

Proper allocation of shell side and tube side fluids in S&T HE

Decision on Baffle arrangement for tube side and shell side taking care of heat transfer and pressure drop

Optimum Tube Lay out taking care of code requirements

Selection of type of heat exchanger based on service which may be single phase (such as the cooling or heating of a liquid or gas) or two-phase (such as condensing or vaporizing).

Corrosion prevention measures, when applicable

Fouling considerations.

Optimum design to evaluate the impact of utility and footprint constraints on the heat exchanger design
