From Gas fields to Engines

Extraction, liquefaction, transport and regasification of LNG is a complicated process involving the use of state-of-the-art technology. The journey of LNG begins in gas fields in Qatar, Algeria or Nigeria and ends up in huge terminals in Asia and Europe.
In the process of liquefying, natural gas reduses its volume almost 600 times.

LNG is colourless and odourless, non-toxic and non-corrosive. The gas is crystal-clear due to the process of liquefaction performed in special LNG terminals where natural gas in gaseous state is supplied from gas fields. The biggest LNG producers own huge volume of natural gas resources. Such is the case of Qatar – the market leader – whose natural gas resources are third largest worldwide.

In the liquefaction terminal, the gas is cooled to -162⁰C (methane boiling point) and then it is transmitted from cryogenic tanks into methane carriers. The biggest vessel of this kind, Q-max, loads up to 266 thousand cubic metres of gas, slightly smaller ones – such as Q-flex which will transport LNG to Świnoujście may carry – 216 thousand cubic metres. Ships from ports in the Arabian Peninsula, Malaysia, Indonesia, Algeria or Australia deliver LNG to Korea, India and Europe. Main transport routes go through the Indian Ocean and the Atlantic Ocean and across the Mediterranean Sea to reach Europe. Shipment from Alaska is directed to Japan across the Pacific Ocean. New routes are established as well, such as the one across the Arctic Ocean: where the Ob River methane carrier sailed from Norway to Japan accompanied by Russian nuclear-powered icebreakers last year.

Having reached the regasification terminal, LNG is unloaded to large tanks, then transferred to regasification facility where it is heated and transformed into gaseous state and subsequently injected in the gas pipeline network. It can also be transported in cisterns by road or rail to smaller LNG stations.
