LPG in its gaseous phase is still heavier than air, unlike natural gas, and thus will flow along floors and tend to settle in low spots, such as basements. There are two main dangers to this. The first is a possible explosion if the mixture of LPG and air is within the explosive limits and there is an ignition source. The second is suffocation ...
In materials science, liquefaction [1] is a process that generates a liquid from a solid or a gas [2] or that generates a non-liquid phase which behaves in accordance with fluid dynamics. [3] It occurs both naturally and artificially. As an example of the latter, a "major commercial application of liquefaction is the liquefaction of air to ...
Liquefied natural gas is natural gas that has been liquefied for the purpose of storage or transport. Since transportation of natural gas requires a large network of pipeline that crosses through various terrains and oceans, a huge investment and long term planning are required. Before transport, natural gas is liquefied by pressurization.
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 ...
There the gas is liquefied in the condenser, where the heat of vaporization is released, and evaporated in the evaporator, where the heat of vaporization is absorbed. Ammonia was the first such refrigerant , and is still in widespread use in industrial refrigeration, but it has largely been replaced by compounds derived from petroleum and ...
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 ...
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.
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 ...
