Development of a novel Petri net tool for process design selection based on inherent safety assessment method

Safety assessment can be implemented using different tools during process design stage. As part of this assessment, the implementation ability and the flexibility of the tools are of great concern. In this paper, a new user-friendly approach using Petri nets as modelling and implementation tool has been presented. Inherent safety methodology is used to assess the safety level of different process options and I2SI indexing system is employed to quantify safety factors. The applicability of this tool is demonstrated through revisiting an aclyric acid production case study taken from literature.
