“…Details of these probit equations can be found in Casal (2008). The probability of indoor fatalities is calculated using the approach presented in API (1995) and Badri et al (2013). In addition, the number of injuries due to each accident (BLEVE and fireball) is a function of the number of fatalities resulting from that accident (Casal, 2008;Medina et al, 2009).…”

There are different well-established strategies for making a process plant inherently safer. The benefits of applying these strategies on reducing the overall risk inside a plant are obvious.However, some of these changes are rejected many times because they appear to be too costly.But if the effects of applying inherently safer design strategies are investigated not only on the processing costs of a plant but also on the potential accident costs, the decision would in fact be different. In this paper an optimization procedure is proposed which integrates both processing and accident costs for different design schemes. In this procedure, some of the design variables are chosen with regard to inherently safer design strategies. The objective function is the sum of accident costs and plant lifecycle processing costs. For assessing accident costs, consequence modeling techniques and probit functions are applied. Consequence modeling formulas and an objective function are codified in an optimizer package (MATLAB) and to accomplish the optimization process a process simulator (called HYSYS) is coupled with this package. The application of the proposed procedure is demonstrated by selecting an optimum process scheme for a Refrigeration plant as a case study.

“…(2011) that the type of material has a significant effect on the outcome of an event tree. Badri et al (2013) proposed a model based on event tree analysis to calculate the vapor cloud explosion frequency, in which they have tried to consider the effect of various parameters influencing the frequency of events. Their idea was to convert the unit into subsets such that the material properties and operating conditions in each specific subset are constant and for each subset, the VCE frequency is calculated and finally the frequencies of all subsets are added together.…”

In this paper, a new method based on Fuzzy theory is presented to estimate the occurrence possibility of vapor cloud explosion (VCE) of flammable materials. This new method helps the analyst to overcome some uncertainties associated with estimating VCE possibility with the Event Tree (ET) technique. In this multi-variable model, the physical properties of the released material and the characteristics of the surrounding environment are used as the parameters specifying the occurrence possibility of intermediate events leading to a VCE. Factors such as area classification, degree of congestion of a plant and release rate are notably affecting the output results. Moreover, the proposed method benefits from experts' opinions in the estimation of the VCE possibility. A refrigeration cycle is used as the case study and the probability of VCE occurrence is determined for different scenarios. In this study, sensitivity analysis is performed on the model parameters to assess their effect on the final values of the VCE possibility. Furthermore, the results are compared with the results obtained using other existing models.
