What are the properties of LNG?

What are the properties of LNG?

LNG is clear, colourless, and odourless. LNG is non-corrosive and non-toxic. The potential hazards of LNG are the result of its basic properties including its cryogenic nature and dispersion and flammability characteristics. Due to its cryogenic nature, LNG will freeze any material it contacts.

What is natural gas analyzer?

Natural Gas Analyzers These analyzers are ideal for your laboratory’s natural gas testing needs. They measure permanent gases (O2, N2, CO2, H2, He) and hydrocarbon content (C1-C5 with C6+ as backflush) and perform extended analysis of hydrocarbons in natural gas to C14.

What is the SG of LNG?


LNG – Liquefied Natural Gas Properties
Natural Gas Chemical Formula CH4 (Methane)
Specific Gravity (Air=1) 0.554
Limits of Flammability 5.3% to 14%
Auto Ignition Temperature 595°C or 1103°F

What is LNG measured in?

metric tonnes
When in liquid form, LNG is commonly measured in metric tonnes. But you will sometimes see it measured in the amount of gas that it will provide when converted back to gaseous form. In this case, common units are billions of cubic meters (bcm) or billions of cubic feet (Bcf).

Which of the following are qualities of LNG?

Its key characteristics are:

  • Comprises mainly methane, colourless, cryogenic liquid.
  • Atmospheric boiling point of -163ºC to -160ºC.
  • Density of 458-463 Kg/m3 (depending on composition).
  • 1 m3 of LNG at atmospheric pressure equals 600 Sm3 of natural gas.

What is the main component of LNG?

LNG is mostly methane plus a few percent ethane, even less propane and butane, and trace amounts of nitrogen.

What does a gas analyzer do?

Gas analyzers are analytical devices that measure the concentration or quality of a specific gaseous compound within a mixture of multiple gases.

How does a gas analyzer work?

An infrared gas analyzer measures trace gases by determining the absorption of an emitted infrared light source through a certain air sample. Infrared light is emitted from some type of source on one end of the chamber, passes through a series of chambers that contains given quantities of the various gases in question.

What is the vapor pressure of LNG?

0.145038 psi
1 kPa = 0.145038 psi. The density of LNG depends on its composition, typically varying between about 405 and 465 kg/m3, depending on temperature, for internationally traded LNG cargoes.

What is the density of LNG?

between 430 kg/m3
The density of LNG falls between 430 kg/m3 and 470 kg/m3 (3.5 to 4 lb/US gal). LNG is less than half the density of water; therefore, as a liquid, LNG will float if spilled on water. Specific gravity is a relative quantity.

How is LNG price measured?

LNG prices are denominated in US dollars per million British thermal units (US$/mmBtu), which is a measure of the price per unit of energy content.

How do you calculate LNG?

The volume of LNG transferred is calculated as the difference between the volumes of LNG contained in the tanks before and after the cargo transfer. The calculation of the volume of LNG contained in a tank, at a given moment, is determined by reading from a measurement table according to the corrected level of LNG.
