Storing hazardous substances is one of the most concern in chemical industries. Liquefied Petroleum Gas (LPG) has been widely used due to its reasonable price, accessibility and high applicability. However, LPG characteristics including flammability and explosive might result in various consequences such as flash fire, explosion, BLEVE and pool fire. The major impacts originated from the LPG storage tanks could be also affected by operational and storage conditions. In order to approach to an inherently safer design (ISD), it is vital to highlight the different aspects of the storage conditions. In this paper, a comparison between pressurized and refrigerant LPG storage tanks has been carried out using Phast 7.2 software. Prior to that, Bow-Tie analysis was performed to identify top events and the related barriers. The results indicated that through utilization of pressurized tanks, more severe consequences could occur and enhanced safety measures shall be required.
