Explosion potential assessment of heat exchanger network at the preliminary design stage

The failure of Shell and Tube Heat Exchangers (STHE) is being extensively observed in the chemical process industries. This failure can cause enormous production loss and have a potential of dangerous consequences such as an explosion, fire and toxic release scenarios. There is an urgent need for as...
