What is LNG?

LNG (Liquefied Natural Gas) is a natural gas liquefied by deep cooling to minus 160 o C after removing impurities. LNG has a major component of methane.

Liquefied Natural Gas (LNG) - Liquefied natural gas

LNG is colorless, odorless, non-toxic and non-corrosive, with a flame temperature of about 2340ºC and lighter than air. The main component is methane (about 95%) and a small amount of other gases.

Natural gas is liquefied at -120ºC to -170ºC (depending on the ratio of the mixture in the gas), making it easy to store and transport. Although there are advantages over gasoline such as higher energy density, reduction of refueling times and environmental pollution reduction, but LNG has not been widely applied in developing countries. The main reason is due to the very high cost of investing in storage and transport facilities, infrastructure, processing equipment and machinery. Therefore, LNG used to be used only in countries with strong industrial development such as US, UK, Japan and European countries.

LNG (Liquefied Natural Gas) is essentially NG (Natural Gas) liquefied gas , the main component is CH 4 gas.

LNG can be seen as an "expanding" gas from natural compressed air (CNG). Natural compressed air must be compressed at a very high pressure of 230 bar to store in tanks transporting to consumption places, this is a major obstacle to the radius of the road radius, it is also a cause making price cheaper than traditional fuels.

LNG overcomes the existing weakness that CNG gas is encountering because it is safer, more accommodating, able to go farther means more economical.

Picture 1 of What is LNG?
LNG is stored in large capacity tanks, they are transported by large cargo ships.

The main component LNG, CH 4, is exploited from the natural gas fields in the sea, leading to the mainland and through a cooling and processing system at -163 degrees Celsius, at which time natural gas becomes a state liquid.

LNG is stored in large capacity tanks, they are transported by large cargo ships from one country to another via sea. On LNG mainland is transported by means of transport to consumption places, LNG will be treated through a special evaporator to turn liquid into pure natural NG gas .

LNG is an alternative fuel source, the current and future supplementary fuel source of each country and LNG is towards an industry that emits clean air after burning to the environment, LNG applied on transport vehicles. transportation and especially LNG is the highlight for thermal power plants of each enterprise with medium and large scale production .

LNG is traded very popular in the international market and becomes an important energy source of many countries in the world such as Japan, Korea, Taiwan, China, European countries and North America . The world's largest exporter of LNG is in the Middle East, Southeast Asia (Malaysia, Indonesia), Australia, Russia. Northeast Asia is a traditional LNG consumption market with Japan being the world's largest importer of LNG with an annual output of about 80 million tons.

Liquefied Petrolium Gas (LPG) - Liquefied gas

LPG is a colorless, odorless gas (added with odors to easily detect when leaked), flame temperature from 1890ºC to 1935ºC, lighter than water but heavier than air.

Gas (Petrolium gas) is a by-product obtained during oil processing. Gas is liquefied to form LPG. The main chemical composition consists of propane, butane and a small amount of propylene, butylene and other gases. In fact, the composition of substances contained in LPG is not uniform. Depending on the standards of the countries, different areas where the ratio between propane and butane varies.

Compressed Natural Gas (CNG) - Compressed natural gas

CNG is a colorless, odorless gas with a flame temperature of about 1950ºC and lighter than air. The main component of CNG includes hydrocarbons, in which methane can account for 95%, ethane accounts for 5% to 10% and a small amount of propane, butane and other gases.

Normally, sulfur flavor is added to make it easier to detect when leaked. Because it is lighter than air, in case of leakage, natural gas (both CNG and LNG) does not cause serious damage like gasoline or LPG.
