LNG is short for liquefied natural gas (LNG), and its main component is methane.
LNG, short for liquefied natural gas. Natural gas is a combustible gas produced naturally in gas fields, which is mainly composed of methane. LNG is condensed into liquid by cooling gaseous natural gas to-162℃ under normal pressure. Liquefied natural gas can greatly save storage and transportation space, and has the characteristics of large calorific value and high performance.
Liquefied natural gas is a clean and efficient energy source. Because importing LNG helps energy consuming countries to realize energy supply diversification and ensure energy security, while exporting LNG helps natural gas producing countries to effectively develop natural gas resources, increase foreign exchange income and promote national economic development, LNG trade is becoming a new hot spot in the global energy market.
As a clean energy source, natural gas is increasingly favored. Liquefied natural gas is listed as the first choice fuel in many countries, and the proportion of natural gas in energy supply is increasing rapidly. Liquefied natural gas (LNG) grows at a high speed of about 12% every year, and becomes one of the fastest growing energy industries in the world.
In recent years, the global production and trade of liquefied natural gas (LNG) has become increasingly active. LNG has become a scarce clean resource and a new hot spot in the world oil and gas industry. In order to ensure the diversification of energy supply and improve the energy consumption structure, some major energy consuming countries pay more and more attention to the introduction of liquefied natural gas, and Japan, South Korea, the United States and Europe are all building lng terminal on a large scale. International oil companies have also shifted their new profit growth point to liquefied natural gas business, and liquefied natural gas will become the next hot energy commodity in the world after oil.
The utilization of natural gas in China is extremely unbalanced, and the proportion of natural gas in China's energy is very small. Judging from the development of natural gas in China, natural gas resources are limited, natural gas production is far less than demand, and the gap between supply and demand is getting bigger and bigger. Although it has not yet formed a scale, the characteristics of LNG determine the rapid development of LNG.
It can be predicted that LNG will become the main force in China natural gas market in the next 10-20 years. In 2007, China imported 2,965,438+/kloc-0,000 tons of LNG, more than three times that of 2006. In June, 2008, the total import volume of liquefied natural gas in China was+0-1/kloc-0.4 million tons, an increase of 18. 14% over the same period in 2007.
While China's economy continues to develop rapidly, the energy power to ensure the economy is extremely scarce. China's energy structure is dominated by coal, with oil and natural gas accounting for only a small proportion, far below the world average. With the country's increasing demand for energy, the introduction of LNG will play an important role in optimizing China's energy structure, effectively solving the dual problems of energy supply security and ecological environment protection, and realizing sustainable economic and social development.
China pays more and more attention to the development of LNG industry. Coastal LNG projects being planned and implemented in China include Guangdong, Fujian, Zhejiang, Shanghai, Jiangsu, Shandong, Liaoning, Ningxia, Tangshan and Hebei. These projects will eventually form a coastal lng terminal and pipeline network.
