HAZOP research has been carried out with the emphasis on LPG storage tank system, which is characterized by high hazard, long shutdown time and large economic loss. Reliability and safety of the project have been improved.
The minimum cut-set of the fault tree was obtained, the major dangerous factors in the explosion elimination processing of LPG tanks were realized, and the corresponding prevention measures to ensure the safety of the explosion elimination processing were suggested.
The simplified equation for relief valves of LPG storage tanks is got based on the formula sited in "Vessel Safety Technical Inspection Regulation" issued by China National Labor Ministry and also based on the related content of " Fire Protection Specification of Architectural Design".
According to the problem of insufficient of land for building of a certain plant, the advantages of using underground LPG storage tanks are analyzed, and it explans the undergroundLPG storage tanks saving ground,materials and safety.
The results of two full scale fire engulfment tests on a 3.6 m3-LPG tank protected with a sublimation coating (THERMOLAG 440) and on a 4.85 m3-LPG tank protected with an intumescent coating (CHARTEK III) are presented.
In two recent instances, in different countries, vehicles fitted with an LPG tank were filled from CNG dispensers.
They are dedicated gas vehicles having a small petrol tank to accommodate a larger LPG tank.
