The volumetric energy density of LNG is approximately 2.4 times that of compressed natural gas (CNG), which makes it economical to transport natural gas by ship in the form of LNG. The energy density of LNG is comparable to propane and ethanol but is only 60 percent that of diesel and 70 percent that of gasoline. [4]
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 ...
A balloon filled with gaseous hydrogen exploding.. A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. [1] In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas, methane, propane, butane.
Energetic materials are a class of material with high amount of stored chemical energy that can be released. [ 1 ] Typical classes of energetic materials are e.g. explosives , pyrotechnic compositions , propellants (e.g. smokeless gunpowders and rocket fuels ), and fuels (e.g. diesel fuel and gasoline ).
Because of its use in construction and demolition, it has become perhaps the most widespread explosive, and thus its toxicity is the most characterized and reported. The concentration of TNT in contaminated soil can reach 50 g kg −1 of soil, where the highest concentrations can be found on or near the surface.
A non-combustible material [17] is a substance that does not ignite, burn, support combustion, or release flammable vapors when subject to fire or heat, in the form in which it is used and under conditions anticipated. Any solid substance complying with either of two sets of passing criteria listed in Section 8 of ASTM E 136 when the substance ...
Global warming is ratcheting up the risk of extreme wildfire growth in California and will continue to do so for decades, even if emissions are reduced.
An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be: chemical energy, such as nitroglycerin or grain dust
