Abstract
The transfer of heat to and from process fluids is an essential part of most chemical and petroleum industries. The most commonly used type of heat-transfer equipment is the ubiquitous shell and tube heat exchanger, Choices are usually a compromise among process design requirements, optimum thermal performance, allowable pressure drop, ease of maintenance, and cost. For the best overall exchanger performance, designers must take into account a wide variety of specific condition and constraints; development of general recommendations is therefore impossible. However, the following brief discussion can help reconcile structural code-oriented specifications, as represented by TEMA standards and strictly thermal design-oriented specification. In this paper for a given heat exchanger, study of the effect of key parameters like baffle spacing, tube outer diameter and tube thickness, tube passes, tube pitch and tube layout in a Shell and tube heat exchanger with single segmental baffles and
