초록
Petrochemical industry sites such as chemical reactors and fuel refineries are the most dangerous sites for explosion accidents. The flame propagation and gas explosion of hydrocarbon gas in a containment is influenced by the structure shape. In this study, a containment structure was tested to understand the effect of the length-to-width ratio on methane gas explosions in a fixed roof storage tank. The results show that the flame development and the pressure curve were stable, and the final averaged pressure remained at 3.8 bar until a length-to-width ratio of three was reached. At a length-to-width ratio of five, the flame front and pressure variation became unstable, the peak pressure increased, and the final pressure decreased; this means that the combustion is a fast-burning and partial explosion. When the structure became longer (ratio greater than eight), the pressure increased sharply to 51.9 bar and then reduced to 3 bar at monitoring point 7 located at the end wall. The pressure behavior shows that the flame propagated over a great distance, which created the explosion condition for the unburned gas in the end area of the containment.
Abstract
Petrochemical industry sites such as chemical reactors and fuel refineries are the most dangerous sites for explosion accidents. The flame propagation and gas explosion of hydrocarbon gas in a containment is influenced by the structure shape. In this study, a containment structure was tested to understand the effect of the length-to-width ratio on methane gas explosions in a fixed roof storage tank. The results show that the flame development and the pressure curve were stable, and the final averaged pressure remained at 3.8 bar until a length-to-width ratio of three was reached. At a length-to-width ratio of five, the flame front and pressure variation became unstable, the peak pressure increased, and the final pressure decreased; this means that the combustion is a fast-burning and partial explosion. When the structure became longer (ratio greater than eight), the pressure increased sharply to 51.9 bar and then reduced to 3 bar at monitoring point 7 located at the end wall. The pressure behavior shows that the flame propagated over a great distance, which created the explosion condition for the unburned gas in the end area of the containment.
