Gas or vapor cloud explosions in petrochemical plants may be highly destructive and may trigger escalation or domino effects. The evaluation of the time frame and a sensitivity analysis of the three approaches (i.e., threshold values based on simplified empirical models, damage probability models, and distributed parameter models) for the analysis of domino events triggered by blast waves were presented. The comparison was made based on the results of a case-study and more specifically for a vapor cloud explosion occurring in a low pressure unit within a hydrocracker plant. The analysis was conducted using semi-empirical approaches as the Multi-Energy and Baker-Strehlow models, and by a Computational Fluid Dynamics code. The first approach proved to be effective for the preliminary identification of any possible domino target.

Abstract
Gas or vapor cloud explosions in petrochemical plants may be highly destructive and may trigger escalation or domino effects. The evaluation of the time frame and a sensitivity analysis of the three approaches (i.e., threshold values based on simplified empirical models, damage probability models, and distributed parameter models) for the analysis of domino events triggered by blast waves were presented. The comparison was made based on the results of a case-study and more specifically for a vapor cloud explosion occurring in a low pressure unit within a hydrocracker plant. The analysis was conducted using semi-empirical approaches as the Multi-Energy and Baker-Strehlow models, and by a Computational Fluid Dynamics code. The first approach proved to be effective for the preliminary identification of any possible domino target.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
