    • what is the difference between LPG and LNG?

      • Liquefied petroleum gas (LPG) and Liquefied natural gas (LNG) are often confused with each other. LPG consists chiefly of propane (C3H8) and butane (C4H10), and is used mainly in domestic and commercial applications (such as fuel for cars). LPG is liquefied by holding it under high pressure. LNG, by contrast, is a liquid at atmospheric pressure but at a very low temperature (approx. – 162° C). LPG’s specific gravity is also totally different from LNG’s: LPG’s components are heavier than air and the gas does not disperse if it escapes. LNG (natural gas), by contrast, is lighter than air and disperses and rarefies very quickly into a mixture that is no longer flammable.
      • The storage of LPG is at a high pressure, unlike the storage of LNG which is at low temperature, and thus requires the use of very different equipment (other material properties, thicknesses, insulation) and standards.
    • what happens at an LNG receiving terminal?

      • LNG arrives at the terminal by ship, is unloaded and stored in tanks, warmed (or regasified) and then delivered to the gas transport network. At this point, its use is identical to that of conventional natural gas. The LNG can be distributed (loaded) by truck and ship as well.

    • what are the effects if LNG escapes from a ship?

      • The ships in which LNG is transported have double hulls so that the risk of leakage during a collision is minimal. Should this happen in an extreme condition, and LNG escapes into the water, then the cold liquid will immediately heat up due to the ambient temperature and the warmer water and the resulting gas cloud will rise and disperse. The LNG will not dissolve or mix with water, but disappear as gas because it is lighter than air. A cloud will be visible around the leakage; this is not a gas cloud, but condensing water vapour due to the cold that is released from the LNG. The flammable natural gas has already risen up out of this.
    • what is the environmental impact of LNG?

      • From the moment the LNG is regasified, the environmental impact is identical to that of natural gas (e.g. fewer CO2 emissions on combustion in comparison with coal). If there is direct environmental exposure, for example through leakage, LNG causes less damage than an oil spill since it will immediately vaporize into the atmosphere.
