Liquefied Natural Gas
Liquefied Natural Gas Chain
Liquefied Natural Gas (LNG) currently represents the most exciting aspect of the international gas landscape. Though the overall percentage of gas transported as LNG is less than 10% of global gas trade, it is growing rapidly, involving an increasing number of buyers and sellers. The past two decades have seen phenomenal growth in the LNG trade—growth that is expected to continue unabated this decade.
LNG is simply an alternative method to transport methane from the producer to the consumer. Methane (CH4) gas is cooled to minus 160°C (or more accurately, –161.5°C (–260°F), converting its gaseous phase into an easily transportable liquid whose volume is approximately 600 times less than the equivalent volume of methane gas. (The exact shrinkage is closer to 610 times, but 600 is commonly quoted.) Thus 600 ft3 of methane gas will shrink to a volume of around 1 ft3 of clear and odorless LNG. It is usually stored and moved at cold temperatures and at low pressure.
Gas converted to LNG can be transported by ship over long distances where pipelines are neither economic nor feasible. At the receiving location, liquid methane is offloaded from the ship and heated, allowing its physical phase to return from liquid to gas. This gas is then transported to gas consumers by pipeline in the same manner as natural gas produced from a local gas field.
The LNG process is more complex than pipeline transportation. The “LNG chain, ” shown below, consists of discrete sections: upstream, midstream liquefaction plant, shipping, regasification, and finally, gas distribution.
LNG technology is not new. The first commercial LNG facility was built in the United States in 1941 in Cleveland as a peak load shaving facility. Gas (delivered via pipeline to the plant) was liquefied during hours or seasons of low demand and heated back to gaseous phase to be pumped into the pipeline grid during periods of high demand. Unfortunately, this plant was closed in 1944 due to a gas leak and subsequent explosion.
You may wonder how auto shipping quotes work and how the price of your car's shipment is calculated. Remember that you always compete with other clients for the space on a truck; thus, higher-priced vehicles get transported first, and even if you place your order early, a more expensive order can always get ahead.

United Parcel Service will probably do it for you, as long as you declare it as a hazardous material, and document it properly.
