INHERENTLY SAFER DESIGN FRAMEWORK FOR THE HEAT EXCHANGER NETWORK AT PRELIMINARY DESIGN STAGE

Shell and Tube Heat Exchangers (STHE) are being widely used in chemical process
industries. These exchangers can be deployed for the heating, cooling, condensation,
boiling, decomposition and evaporation operations. The failure of these exchangers is
frequently experienced in industries. Moreover, the loss of containment scenarios from
these heat exchangers could potentially create a fire and explosion events. Lack of
consideration in inherently safer design and inadequate safety analysis are considered
as the noticeable issues in the failure of these heat exchangers. The frequency of
credible events from the various leak scenarios of these heat exchangers can be
effectively reduced by applying inherently safer design (ISD) strategies.
