Safety Assessment of Production Process of Styrene

Dow Fire and Explosion Index (F&EI) is employed to evaluate the safety of the styrene production unit. Both the inherent F&EI and the F&EI taking the Loss Control Measures (LCM) are calculated. The calculation results show that F&EI with LCM reduced 41.25% compared with inherent F&EI. Then, the Radius of Exposure and Area of Exposure are calculated, which refer to the probable damage range in case of fire and/or explosion. Last, the loss of the unit is calculated and the result is given in the term of dollars, which is direct and simple. The results can provide important information to managers, workers and residents around plants.
