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 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.
As LNG warms above its storage temperature, the liquid begins to vaporize. The resulting gas produced by this warming is typically methane, which is the major component (with some ethane) of natural gas and one of the most potent and hazardous greenhouse gases. If a spill occurs and the vapor does not ignite, it would build to higher ...
Regasification is a process of converting liquefied natural gas (LNG) at −162 °C (−260 °F) temperature back to natural gas at atmospheric temperature. LNG gasification plants can be located on land as well as on floating barges, i.e. a Floating Storage and Regasification Unit (FSRU). Floating barge mounted plants have the advantage that ...
The way federal regulators approach natural gas safety should be comparable to their stringent approach to nuclear energy, said Naomi Yoder, a data manager who focuses on LNG at the Bullard Center ...
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
In my previous article, we saw how an escalating global demand for natural gas creates an argument for its export. But that alone won't make U.S. exports profitable. There are other major factors ...
