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 ...
NGL is first pumped as liquid to this pressure. A series of heat exchangers are used to regasify the LNG. These may include submerged combustion vaporisers, [15] or an intermediate fluid exchanger (using propane or other fluids), [16] or the use of waste heat from a nearby plant such as a power station.

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.

Petroleum refinery in Anacortes, Washington, United States. Petroleum refining processes are the chemical engineering processes and other facilities used in petroleum refineries (also referred to as oil refineries) to transform crude oil into useful products such as liquefied petroleum gas (LPG), gasoline or petrol, kerosene, jet fuel, diesel oil and fuel oils.
A natural-gas processing plant in Aderklaa, Austria. Natural-gas processing is a range of industrial processes designed to purify raw natural gas by removing contaminants such as solids, water, carbon dioxide (CO 2), hydrogen sulfide (H 2 S), mercury and higher molecular mass hydrocarbons to produce pipeline quality dry natural gas [1] for pipeline distribution and final use.

Between 2005 and 2014, US production of natural gas liquids (NGLs) increased 70 percent, from 1.74 million barrels per day in 2005 to 2.96 million barrels per day in 2014. Although the United States leads the world in natural gas production, it is only fifth in proved reserves of natural gas, behind Russia, Iran, Qatar, and Turkmenistan.
Natural gas burning on a gas stove Burning of natural gas coming out of the ground. Natural gas (also called fossil gas, methane gas, or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) [1] in addition to various smaller amounts of other higher alkanes.
