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.
The Kværner process or Kvaerner carbon black and hydrogen process (CB&H) [162] is a method, developed in the 1980s by a Norwegian company of the same name, for the production of hydrogen from hydrocarbons (C n H m), such as methane, natural gas and biogas.
Liquefied hydrogen is the liquid state of the element hydrogen. It is a common liquid rocket fuel for rocket applications and can be used as a fuel in an internal combustion engine or fuel cell . Various concept hydrogen vehicles have been lower volumetric energy, the hydrogen volumes needed for combustion are large.
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 ...
In this way, the production of renewable gas can be phased in at the same rate as the production capacity is increased. The gas market and infrastructure the natural gas has contributed with is a condition for large scale introduction of renewable biomethane produced through anaerobic digestion ( biogas ) or gasification and methanation bio-SNG.
The country’s export capacity for liquefied natural gas, or LNG, is almost entirely located on the Gulf Coast. ... A fire marshal’s report gives some insight into the Freeport LNG explosion in ...
