What is the meaning of LNG and NGL, and their dofferences?

Question

technically, in natural gas engieering, we have natural gas liquid and liquefied natural gas.

Answer 1

LNG stands for Liquefied Natural Gas. It generally is 95% - 99+% methane. It is produced at a temp of about -258 deg F and stored in insulated tanks. It is very clean burning and as such is becoming desirable as a fuel for vehicles (usually fleet vehicles such as buses) as well as the traditional use of gas to homes.
NGL stands for Natural Gas Liquids. This means basically any hydrocarbon heavier than methane. The tank trucks that haul propane are classed NGL trailers. This includes propane and butane. Most NGL liquids are produced and stored at abient temperatures under pressure. Propane tank pressure is typically less than 208 psig at 100 deg F and butane is 70 psig at 100 deg F.

Answer 4

Liquefied natural gas or LNG is natural gas that has been processed to remove impurities and heavy hydrocarbons and then condensed into a liquid at atmospheric pressure by cooling it to approximately -163 degrees Celsius.

With respect to petroleum production, Natural gas liquids are the liquids that, combined with methane, form unprocessed natural gas. These liquids include ethane, propane, butane, isobutane and natural gasoline[1] (sometimes called condensate).

Answer 6

LNG is natural gas cooled to a liquid state. It is made up of mostly methane.When
natural gas is cooled to a temperature of approximately -256°F at
atmospheric pressure, it condenses to a liquid. To liquefy natural gas,
impurities that would freeze are removed, such as water, carbon dioxide,
sulfur, and some of the heavier hydrocarbons. The volume of this liquid
takes up about 1/600th of the volume of natural gas at a stove burner tip.The liquefaction process requires the
removal of the non-methane components like carbon dioxide, water, butane,
pentane and heavier components from the produced natural gas.
CNG is natural gas that is pressurized and stored in welding bottle-like tanks at
pressures up to 3,600 psig.
NGL- are made up mostly of molecules that are
heavier than methane like ethane, propane, and butane.
LPG- is a mixture of propane and butane in a liquid state at room temperatures.
GTL- refers to the conversion of natural gas to products like methanol, diethyl ether (DME),
middle distillates (diesel and jet fuel), specialty chemicals and waxes.
