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 ...
"Liquefied natural gas or LNG is natural gas (primarily methane, CH4) that has been converted to liquid form for ease of storage or transport. Liquefied natural gas takes up about 1/trillionth the volume of natural gas at a stove burner tip. It is odorless, colorless, non-toxic and non-corrosive. Hazards include flammability, freezing and ...
Natural gas itself is combustible; it’s primarily made of methane, a potent planet-warming gas, and it’s the fuel we burn in our homes to power things like gas stoves and furnaces.
In fire and explosion prevention engineering, purging refers to the introduction of an inert (i.e. non-combustible) purge gas into a closed system (e.g. a container or a process vessel) to prevent the formation of an ignitable atmosphere. Purging relies on the principle that a combustible (or flammable) gas is able to undergo combustion ...
LPG is composed mainly of propane and butane, while natural gas is composed of the lighter methane and ethane. LPG, vaporised and at atmospheric pressure, has a higher calorific value (46 MJ/m 3 equivalent to 12.8 kWh/m 3) than natural gas (methane) (38 MJ/m 3 equivalent to 10.6 kWh/m 3), which means that LPG cannot simply be substituted for ...
On Aug. 19, there was a natural gas explosion at a strip mall in Balch Springs, east of Dallas. The explosion and subsequent fire sent 10 people to the hospital, according to Railroad Commission ...
Cheap and abundant North American natural gas is fueling more than just homes and businesses. It's fueling explosive dividend growth for heavy users including fertilizer producer CF Industries .
