Liquefied gas Horton tanks similar to the six spherical tanks involved in the San Juanico disaster LPG bullet tanks. There were 48 tanks of this type in the Pemex plant. Note how this modern installation incorporates some of the lessons learned from San Juanico: an uncongested, well ventilated area, with the horizontal tanks in a parallel cluster configuration, which minimizes the effects of ...
During the journey, solar radiation and ambient temperature heated the liquefied gas. Under normal circumstances, the presence of ullage gas vapors would have meant an increase in pressure well within the mechanical limits of the tank. However, the tank was hydraulically full, which meant that the liquid had no room left to thermally expand ...
The heating value depends on the source of gas that is used and the process that is used to liquefy the gas. The range of heating value can span ±10 to 15 percent. A typical value of the higher heating value of LNG is approximately 50 MJ/kg or 21,500 BTU/lb. [2] A typical value of the lower heating value of LNG is 45 MJ/kg or 19,350 BTU/lb.
If saturated LNG contacts liquid water (e.g. sea water, which has an average temperature of 15 °C), heat is transferred from the water to the LNG, rapidly vaporizing it. This results in an explosion because the volume occupied by natural gas in its gaseous form is 600 times greater than when its liquefied; this is the phenomenon of rapid phase ...
The physical mechanisms producing the above heat-release fluctuations are numerous. [1] [8] Nonetheless, they can be roughly divided into three groups: heat-release fluctuations due to mixture inhomogeneities; those due to hydrodynamic instabilities; and, those due to static combustion instabilities. To picture heat-release fluctuations due to ...
The main danger with a heat wave is probably obvious: too much time spent in the heat can quickly lead to illnesses such as heat exhaustion or heat stroke, which could prove fatal.
Liquefied petroleum gas, also referred to as liquid petroleum gas (LPG or LP gas), is a fuel gas which contains a flammable mixture of hydrocarbon gases, specifically propane, n-butane and isobutane. It can sometimes contain some propylene , butylene , and isobutene .
