Natural Gas liquefaction - LNG
Natural gas is cooled to -162°; C for liquefaction. In liquid form, natural gas (LNG) has just 1/600 of the volume in its gaseous state and thus permits much more cost-efficient transportation over long distances. Natural gas is often transported in liquefied state if the construction of pipelines and conduits would only be possible with difficulty due to long distances, geological or political conditions.
LNG liquefaction plants are operated both on-shore and off-shore. In the case of off-shore plants, the liquefaction is carried out by special tanker ships.
Bernd Engelhart, Director of 'ADK Gas-Technologies' estimates that increasing oil prices and the growing divide between mineral oil and natural gas price on the one hand and growing regional markets on the other hand will drive the global LNG market further forwards. Tightened ecological regulations for pollutants can be efficiently fulfilled by the use of LNG, for example in the shipping industry.
